[0061] The techniques and systems described in this paper relate to methods for determining the six-degree-of-freedom (6-DoF and / or 6DOF) pose and relative dimensions of an object from an image using one or more neural networks. The 6-DoF pose can refer to the object's three-dimensional (3D) position and orientation. The relative dimensions of the object can refer to the relative dimensions of the object's 3D enclosing cuboid, and can be expressed as the ratio of the width, height, and length of the 3D enclosing cuboid. The system for object pose estimation can calculate the object's 6-DoF pose and relative dimensions from an image depicting the object.
[0062] In one embodiment, the system for object pose estimation acquires RGB (red-green-blue) images depicting objects of a specific category. The category can refer to a classification or class of objects, where objects belonging to that category can be similar; for example, a category referred to as "mug" could include instances of mugs with different colors, sizes, with or without handles, and / or variations thereof. The system can utilize a neural network to extract features from the image and compute individual outputs based at least in part on the extracted features. In some embodiments, the output includes an indication of the object's bounding box center, an indication of the bounding box size, an indication of the vertices of the cuboid the object surrounds, and the relative dimensions of the cuboid. The system can decode one or more of these outputs and utilize an n-point perspective (PnP) algorithm to compute the object's 6-DoF pose and relative dimensions. The system can be trained using various training images depicting objects with annotations indicating the object's 6-DoF pose and relative dimensions.
[0063] The system can perform category-level object pose estimation using a single-stage, keypoint-based approach, and can detect, compute 6-DoF poses, and estimate the relative dimensions of unseen object instances within known categories. The system can utilize neural networks to perform 2D object detection, keypoint detection, and regression of the relative dimensions of the enclosing cuboid, which can be estimated sequentially. The system may include post-processing steps to extract the cuboid's vertex coordinates and relative dimensions. The system can be used in various contexts, such as for robotic grasping of unknown objects. For example, a robotic arm operating in an unconstrained environment can use the system to determine what objects are nearby and where they are located (e.g., 6-DoF poses), allowing the robotic arm to grasp objects in a semantically meaningful manner.
[0064] In various embodiments, the system performs category-level pose estimation, which involves inferring the pose and relative size of all objects within a specific category using RGB images processed by a single neural network. The system can handle all instances within a specific category. The system can be based on an RGB-based method (e.g., without depth) and may require 3D bounding box annotations during training. The system can be trained using various datasets, such as the Objectron dataset or any suitable dataset.
[0065] This system can utilize a single-step neural network to regress object locations in an image, 2D keypoint projections of 3D bounding box vertices, and the relative size of the bounding box. To handle intra-class shape variations, the system can utilize dual representations of displacement and heatmaps for keypoint detection. During inference, since objects within the same class can have different 3D aspect ratios, the system can estimate the relative cuboid size using various PnP algorithms. The system can group network output patterns according to complexity and compute each output group using convolutionally gated recurrent units (convGRUs) that sequentially refine the hidden states from the bottom layer; in this way, the complexity and / or difficulty of predicting subsequent groups can be reduced by using information from previous groups stored in the hidden states.
[0066] In one embodiment, the system utilizes a single-step keypoint-based network to detect previously unseen objects of known categories from RGB images (e.g., without depth) and estimates their 6-DoF pose and relative bounding box size. The system can perform 2D keypoint detection using a combined representation of displacement and heatmaps and can estimate the relative size of a 3D bounding box. In some examples, the system leverages sequential feature associations to improve the accuracy of estimating multiple groups of outputs from the network.
[0067] Various techniques have been described above and below. For illustrative purposes, specific configurations and details have been presented to provide a thorough understanding of the possible ways to implement these techniques. However, it is also apparent that the techniques described below can be practiced in different configurations without specific details. Furthermore, well-known features may be omitted or simplified to avoid obscuring the described techniques.
[0068] The techniques described and suggested in this disclosure improve the field of object pose estimation by providing a system that determines the 6-DoF pose and relative dimensions of an object from a single RGB image depicting the object. Furthermore, the techniques described and suggested in this disclosure improve the speed and accuracy of robotic systems that require 6-DoF pose and / or relative dimension information for individual object grasping tasks. Moreover, the techniques described and suggested in this disclosure must be rooted in computer technology to overcome the specific problems that arise from using a single RGB image of an object to determine its 6-DoF pose and / or relative dimensions.
[0069] Figure 1 Example 100 of a system for object pose estimation according to at least one embodiment is illustrated. In some examples, system 102 for object pose estimation is referred to as a single-step keypoint-based category-level object pose estimation from an RGB image system and / or its variants. System 102 for object pose estimation can predict the 2D projection of the corners of a 3D-enclosing cuboid, followed by a PnP algorithm. System 102 for object pose estimation can directly estimate all predictions via a single-step network, including the relative dimensions of the cuboid, which can be used in the PnP algorithm. System 102 for object pose estimation can include a ratio Figure 1 The components shown may be fewer or more components, which may include any suitable functionality.
[0070] In at least one embodiment, the system 102 for object pose estimation is a collection of one or more hardware and / or software computing resources having instructions, when executed, to calculate the 6-DoF pose and relative size of an object depicted in an image. The system 102 for object pose estimation can be a software program, application program, software module, and / or variations thereof, executing on computer hardware. In some examples, one or more processes of the system 102 for object pose estimation are executed by any suitable processing system or unit (e.g., graphics processing unit (GPU), parallel processing unit (PPU), central processing unit (CPU)) in any suitable manner, including sequential, parallel, and / or variations thereof.
[0071] System 102 for object pose estimation may receive or otherwise acquire input image 104 and provide input image 104 to feature extraction 106 for computation of feature maps. Feature extraction 106 may output feature maps to groups 108, 116, and 124. Group 108 may compute object center heatmap 110, object center offset 112, and 2D bounding box size 114; group 116 may compute keypoint heatmap 118, keypoint offset 120, and XY displacement 122; and group 124 may compute relative size 126. Groups 108, 116, and 124 may be part of a convGRU network. The 2D keypoint output decoder 128 can process the object center heatmap 110, object center offset 112, 2D bounding box size 114, keypoint heatmap 118, keypoint offset 120, and XY displacement 122, and the PnP algorithm 130 can process the output of the 2D keypoint output decoder 128, relative size 126, and camera intrinsic parameters 132 to calculate 6-DoF pose and size 134.
[0072] In one embodiment, the input image 104 is an image of any suitable image format (e.g., red-green-blue (RGB) image, black / white (B / W) image, grayscale image, RGB-D image, and / or variations thereof), which may be stored or otherwise encoded using any suitable image file format (e.g., bitmap image file, JPEG (Joint Image Experts Group) file, SVG (Scalable Vector Graphics) file, and / or variations). The input image 104 may be a video frame. The input image 104 may be captured by one or more image and / or video capture systems. In one embodiment, the input image 104 may be captured from one or more systems of an autonomous device (such as a robot). The input image 104 may be captured from any suitable system, such as a vehicle system (e.g., an autonomous vehicle, a semi-autonomous vehicle), a medical device (e.g., a medical imaging device), an autonomous device (e.g., a robot), and / or any suitable system.
[0073] In some examples, the input image 104 is an RGB image with a resolution (e.g., height × width) represented by H × W. The system 102 for object pose estimation can rescale and / or pad the input image 104 such that W = H = 512. The input image 104 can be represented as Input image 104 can be provided to feature extraction 106. In at least one embodiment, feature extraction 106 is a collection of one or more hardware and / or software computing resources having instructions that, when executed, compute one or more feature maps from the image. Feature extraction 106 can be a software program, application program, software module, and / or variations thereof executing on computer hardware, and may be part of system 102 for object pose estimation.
[0074] Feature extraction 106 can implement various neural network processes to generate feature maps from input image 104. Feature extraction 106 can perform any suitable feature extraction process, such as those including operations such as convolution, pooling, upsampling, downsampling, aggregation, concatenation, skip connections, activation functions, projection, interpolation, normalization, and / or variations thereof, to generate feature maps. In one embodiment, a feature map, which may be called an activation map, is a set of data used to indicate the output activation of a given filter. Feature maps can indicate the output of one or more operations applied to the input. Feature maps can indicate various features of the image. In some examples, the channels of the feature map correspond to various features and / or aspects of the feature map. In at least one embodiment, each channel of the feature map represents an aspect of information, such as a particular feature (e.g., edge, corner), a particular color (e.g., red, blue, green), and / or variations thereof. Feature extraction 106 can perform any suitable process for determining feature maps from input image 104. Feature maps can be represented as...
[0075] In one embodiment, feature extraction 106 implements a neural network such as a Deep Aggregation (DLA) 34 network combined with upsampling, where hierarchical aggregation connections are enhanced by deformable convolutional layers. Feature extraction 106 can generate multiple intermediate feature maps at different resolutions, ranging from H / 4×W / 4 to H / 32×W / 32, or any suitable resolution, which can be aggregated into a single output (with H / 4×W / 4 resolution or any suitable resolution). Feature extraction 106 can output the feature maps to groups 108, 116, and 124.
[0076] Groups 108, 116, and 124 can be part of a convGRU network. In one embodiment, the convGRU network is a neural network utilizing one or more gated recurrent units (GRUs) and one or more convolutional operations. The convGRU network can utilize fully convolutional networks, recurrent neural networks, and / or variants thereof. The convGRU network can output various data (e.g., object center heatmap 110, object center offset 112, 2D bounding box size 114, keypoint heatmap 118, keypoint offset 120, XY displacement 122, and relative size 126), where groups 108, 116, and 124 can each correspond to one or more outputs. The convGRU module can associate features with three consecutive groups and regress on a total of seven different outputs, where each output can be... In this context, c represents the number of channels. In one embodiment, groups 108, 116, and 124 each correspond to one or more layers of the convGRU network. In some examples, some network outputs of this network are more complex and / or harder to learn than the network outputs of other networks, where the outputs can be divided into three groups (e.g., groups 108, 116, and 124).
[0077] Group 108 may correspond to object center heatmap 110, object center offset 112, and 2D bounding box size 114. Group 116 may correspond to keypoint heatmap 118, keypoint offset 120, and XY displacement 122. Group 124 may correspond to relative size 126, also known as relative cuboid size. Group 124 may be complex and / or difficult to estimate because, in some examples, the 3D structure is implicitly derived from the 2D appearance. In some embodiments, once the object centroid and 2D bounding box are estimated, keypoints are easier to find, and similarly, once the keypoints are found, the bounding box size is easier to determine. One or more systems may assign different output groups to different time steps in a recurrent neural network. In one embodiment, for system 102 for object pose estimation, given an input image denoted as I, the i-th output (e.g., i = 1, ..., 7, corresponding to object center heatmap 110, object center offset 112, 2D bounding box size 114, keypoint heatmap 118, keypoint offset 120, XY displacement 122, and relative size 126, respectively) is expressed by the following formula, although any variations thereof may be used:
[0078] y i =Ψ i (G t (Φ(I), h t-1 ))
[0079] Where Φ(I) represents the feature map from the backbone network (e.g., feature extraction 106), G t(·) represents the GRU at time step t, h t-1 =G t-1 (Φ(I), h t-2 ) represents the hidden state generated by the GRU unit at the previous time step h0 = 0, while Ψ i Let represent the fully convolutional network with the i-th output. Time steps t = 1, 2, 3 can correspond to three output groups (e.g., group 108, group 116, and group 124).
[0080] System 102 for object pose estimation can implement various output grouping and sequential feature association processes. System 102 for object pose estimation can utilize a single-layer convolutional GRU network, where all convolutional layers in the convGRU are set to stride = 1, kernel size = 3, and output channels = 64, although any suitable values can be used. The output at a later time step can access the hidden states flowing from its previous time step. The network can have seven output heads (e.g., corresponding to object center heatmap 110, object center offset 112, 2D bounding box size 114, keypoint heatmap 118, keypoint offset 120, XY displacement 122, and relative size 126), arranged in three groups (e.g., group 108, group 116, and group 124). Output heads can refer to one or more layers, processes, etc., of the neural network that produce the output. For each output head, the system 102 for object pose estimation can utilize a 3×3 convolutional layer with 256 channels, followed by a 1×1 convolutional layer, to produce the output, or any suitable layer of appropriate size and / or channels. In one embodiment, the output is predicted as a dense heatmap or regression map, but sparsely accessed corresponding to the detected object centers, as described in further detail herein.
[0081] In at least one embodiment, group 108 is a collection of one or more hardware and / or software computing resources having instructions that, when executed, perform one or more neural network processes. Group 108 may be a software program, application program, software module, and / or variations thereof executing on computer hardware, which may be part of system 102 for object pose estimation. Group 108 may implement one or more layers and / or processes of a neural network that process feature maps to output object center heatmap 110, object center offset 112, and 2D bounding box size 114. Group 108 may process a set of features (e.g., feature maps) to determine or otherwise predict a first set of data and / or values indicative of object center heatmap 110, object center offset 112, and 2D bounding box size 114.
[0082] In one embodiment, object center heatmap 110 is a heatmap indicating one or more centers of one or more objects depicted in an image (e.g., input image 104). In some examples, the heatmap is a graphical representation of data that utilizes color coding to represent different values and / or magnitudes of a phenomenon (e.g., color gradients, where lighter colors represent lower values and / or magnitudes, darker colors represent higher values and / or magnitudes, and / or variations thereof). The heatmap may be defined by color values (e.g., confidence values) corresponding to the values of the phenomenon. Object center heatmap 110 may be an image or other visualization. Object center heatmap 110 may include a confidence value corresponding to each pixel of input image 104. The confidence value may refer to a probability value determined by a neural network for the output, indicating the probability that the output is correct. As an illustrative example, the values of object center heatmap 110 correspond to pixels of input image 104 and to confidence values indicating the confidence level of a pixel's location corresponding to the center of an object.
[0083] The object center heatmap 110 may include peaks indicating the center of the 2D bounding box of all detected objects in the input image 104. In one embodiment, the peak of the heatmap refers to the location in the heatmap corresponding to the maximum confidence value (e.g., a first maximum, a second maximum, etc.). In some embodiments, other output maps are accessed relative to the object center, such that if in the (c x c y If the peak value is found in the heatmap of the object center at the location indicated by ), then the remaining output (c) x c y The value at () is associated with the object.
[0084] A bounding box can refer to a box or rectangular shape that indicates the location of an object. In some examples, a 2D bounding box is defined as the smallest rectangle that encloses the extreme points of the 3D bounding box surrounding the projection. Object center offset 112 can be a set of data indicating one or more offset values. Object center offset 112 can include two sets of data, each set including the value of each pixel in the input image 104. The first set of data can include offset values in the x-axis direction, and the second set of data can include offset values in the y-axis direction. The offset values can be used by the system 102 for object pose estimation to recover discretization errors that may be caused by the resolution of the heatmap output. In some examples, the system 102 for object pose estimation (e.g., via 2D keypoint output decoding 128) determines the pixel coordinates of the input image 104 corresponding to the peak of the object center heatmap 110 and uses the offset values from the object center offset 112 corresponding to the pixel coordinates to further refine the determination of the object center in the input image 104.
[0085] The 2D bounding box size 114 can be a set of data indicating the width and height values of the object's bounding box. The 2D bounding box size 114 can include two sets of data, each including the value for each pixel of the input image 104. The first set of data can include width values, and the second set can include height values. The system 102 for object pose estimation can utilize the 2D bounding box size 114 to determine the size of the bounding box of the object depicted in the input image 104. In some embodiments, the system 102 for object pose estimation (e.g., via 2D keypoint output decoding 128) determines the pixel coordinates of the input image 104 corresponding to the center of the object and uses the width and height values from the 2D bounding box size 114 corresponding to the pixel coordinates to determine the size of the object's bounding box.
[0086] In at least one embodiment, group 116 is a collection of one or more hardware and / or software computing resources having instructions that, when executed, perform one or more neural network processes. Group 116 may be a software program, application program, software module, and / or variant thereof executing on computer hardware, which may be part of system 102 for object pose estimation. Group 116 may implement one or more layers and / or processes of a neural network that process feature maps to output keypoint heatmap 118, keypoint offset 120, and XY displacement 122. Group 116 may process a set of features (e.g., feature maps) to compute or otherwise predict a second set of data indicating keypoint heatmap 118, keypoint offset 120, and XY displacement 122. System 102 for object pose estimation may utilize group 116 to determine the aspects of the enclosing cuboid of an object depicted in input image 104. The enclosing cuboid (also referred to as a 3D bounding box, 3D enclosing cuboid, and / or variant thereof) may refer to a cuboid indicating the 3D position and orientation of an object within an image.
[0087] In one embodiment, keypoint heatmap 118 is one or more heatmaps indicating keypoints of the 3D bounding box of an object depicted in an image (e.g., input image 104). Keypoint heatmap 118 may include one or more images or other visualizations. Each heatmap in keypoint heatmap 118 may include a confidence value corresponding to each pixel of input image 104. As an illustrative example, the values of the heatmaps in keypoint heatmap 118 correspond to pixels in input image 104 and to confidence values indicating the confidence level of a pixel's position relative to a vertex of the object's 3D bounding box. Keypoint heatmap 118 may include eight heatmaps, each of which may correspond to a keypoint of the 3D bounding box of the object in input image 104. The heatmaps in keypoint heatmap 118 may include peaks indicating keypoint positions. In one embodiment, a keypoint corresponds to a vertex of the 3D bounding box. Keypoints may be indicated by 2D coordinates projected onto the vertices of the 3D bounding box in image space. In one embodiment, the keypoint heatmap 118 includes a set of eight keypoint heatmaps, wherein the peaks of the heatmaps indicate the 2D coordinates of the projected 3D vertices.
[0088] Keypoint offset 120 can be a dataset indicating one or more offset values. Keypoint offset 120 can include 16 sets of data, where each set includes the value of each pixel in the input image 104. Each set of data in keypoint offset 120 can include an offset value in a specific direction (e.g., the x-axis or y-axis direction) for a particular keypoint. For each keypoint, a first set of data can include the offset value of the first keypoint in the x-axis direction, a second set of data can include the offset value of the first keypoint in the y-axis direction, a third set of data can include the offset value of the second keypoint in the x-axis direction, a fourth set of data can include the offset value of the second keypoint in the y-axis direction, and so on. In one embodiment, there are eight keypoints, where each keypoint corresponds to a vertex of a 3D bounding box. The offset values can be used by the system 102 for object pose estimation to mitigate the discretization error of each vertex. In some examples, system 102 for object pose estimation (e.g., via 2D keypoint output decoding 128) determines the pixel coordinates of input image 104 corresponding to peaks in the heatmap of keypoint heatmap 118 corresponding to specific keypoints, and further refines the determination of specific keypoints using offset values from keypoint offset 120 corresponding to the pixel coordinates. System 102 for object pose estimation (e.g., via 2D keypoint output decoding 128) can use keypoint heatmap 118 and keypoint offset 120 to determine the pixel coordinates of each keypoint of the 3D bounding box of the object depicted in input image 104.
[0089] XY displacement 122 can be a set of data indicating one or more vectors. XY displacement 122 can include sixteen sets of data, each indicating one or more vectors. XY displacement 122 can indicate vectors that indicate keypoint locations. In some examples, set 116 regresses XY displacement 122 from the bounding box center point. System 102 for object pose estimation (e.g., via 2D keypoint output decoding 128) can utilize keypoint heatmap 118, keypoint offset 120, and / or XY displacement 122 to compute the pixel coordinates of each keypoint. In one embodiment, during training, a Gaussian kernel centered on ground truth keypoint coordinates, with its variance determined by the size of the 2D bounding box.
[0090] In at least one embodiment, group 124 is a collection of one or more hardware and / or software computing resources having instructions that, when executed, perform one or more neural network processes. Group 124 may be a software program, application program, software module, and / or variations thereof executing on computer hardware, which may be part of a system for object pose estimation 102. Group 124 may implement one or more layers and / or processes of a neural network that process feature maps to output relative dimensions 126. Group 124 may compute or otherwise predict a set of values indicating relative dimensions 126. The relative dimensions of an object (e.g., an object depicted in an image) may refer to the relative dimensions of the object's enclosing cuboid and may be expressed as the ratio of the width, height, and length of the enclosing cuboid.
[0091] The relative size 126 can be a dataset indicating the estimated relative dimensions (e.g., width, height, length) of the 3D enclosing cuboid. The relative size 126 can include three sets of data, each including the value for each pixel of the input image 104. The first set of data can include width values, the second set can include height values, and the third set can include length values. In some examples, the relative values enable the system 102 for object pose estimation to process images acquired using different camera intrinsic parameters without having to retrain one or more networks for object pose estimation. The system 102 for object pose estimation can utilize the y-axis as the principal axis. The ground truth scale can be processed as (x / y, 1, z / y), where the respective ratios x / y and z / y are estimated by the system 102 for object pose estimation. The system 102 for object pose estimation can directly regress each ratio. The system 102 for object pose estimation can utilize the relative size 126 to determine the relative dimensions of the enclosing cuboid of the object depicted in the input image 104.
[0092] In at least one embodiment, the 2D keypoint output decoder 128 is a collection of one or more hardware and / or software computing resources with instructions that, when executed, perform one or more decoding processes. The 2D keypoint output decoder 128 may be a software program, application program, software module, and / or variant thereof executing on computer hardware, and may be part of the system 102 for object pose estimation. The 2D keypoint output decoder 128 may calculate keypoint positions based at least in part on object center heatmap 110, object center offset 112, 2D bounding box size 114, keypoint heatmap 118, keypoint offset 120, and / or XY displacement 122.
[0093] The 2D keypoint output decoder 128 can apply pooling operations (e.g., 3×3 max pooling) to a heatmap of the 2D object's center (e.g., object center heatmap 110) to search for all local maxima within a window. For each detected center point, the displacement-based keypoint location can be indicated by the keypoint coordinate offset below the center point (e.g., XY displacement 122). The 2D keypoint output decoder 128 can extract heatmap-based keypoint locations by determining high-confidence peaks in the corresponding heatmap (e.g., keypoint heatmap 118) within the bounding box of the 2D object. The 2D keypoint output decoder 128 can adjust the keypoint location estimate based on the offset (e.g., the offset in keypoint offset 120). The 2D keypoint output decoder 128 can process a first set of data and a second set of data to compute a set of coordinates indicating the keypoint location, which may correspond to the vertices of the object's bounding box. The 2D keypoint output decoder 128 can input the keypoint location into the PnP algorithm 130, where the keypoint location can be indicated by the coordinates of the keypoint location.
[0094] PnP algorithm 130 can acquire keypoint positions calculated by 2D keypoint output decoding 128, relative dimensions 126, and camera intrinsic parameters 132. In at least one embodiment, PnP algorithm 130 is a collection of one or more hardware and / or software computing resources having instructions that, when executed, perform one or more PnP processes. PnP algorithm 130 can be a software program, application program, software module, and / or variant thereof executing on computer hardware, which can be part of a system for object pose estimation 102. PnP algorithm 130 can perform various PnP processes, which can refer to the process of estimating the relative pose (e.g., 3D position and orientation) between a calibrated perspective camera and a 3D object (or between the camera and the entire 3D scene) from a set of visible 3D points with known object coordinates and their 2D projections with known pixel coordinates. PnP algorithm 130 can implement one or more PnP algorithms, such as EPnP, a Levenberg-Marquardt version of PnP, or any suitable PnP algorithm.
[0095] Camera intrinsic parameters 132 may be a set of data indicating intrinsic parameters of the image and / or video capture device used to capture the input image 104. In one embodiment, camera intrinsic parameters, also referred to as camera intrinsic parameters or camera internal parameters, are parameters and / or other information inherent to the image and / or video capture device (such as a camera). Camera intrinsic parameters may include information such as focal length, lens distortion, optical center, and / or variations thereof. The system 102 for object pose estimation may obtain or otherwise provide camera intrinsic parameters 132 from one or more systems connected to one or more image and / or video capture devices. In one embodiment, one or more systems capture the input image 104 and provide camera intrinsic parameters 132 to the system 102 for object pose estimation. Camera intrinsic parameters 132 may also be referred to as a set of data corresponding to an image capture device (e.g., the image capture device that captures the input image 104).
[0096] The PnP algorithm 130 can process keypoint positions calculated from 2D keypoint output decoding 128, relative dimensions 126, and camera intrinsic parameters 132 to output 6-DoF pose and dimensions 134. The PnP algorithm 130 can output a set of values indicating the 6-DoF pose and dimensions 134. The 6-DoF pose and dimensions 134 can be a set of data indicating the 6-DoF pose of an object depicted in the input image 104 and the relative dimensions of its enclosing cuboid. The 6-DoF pose can be indicated by one or more values corresponding to x-axis position, y-axis position, z-axis position, roll axis angle, pitch axis angle, and / or yaw axis angle. The 6-DoF pose can be indicated by the enclosing cuboid (e.g., the coordinates of the vertices of the enclosing cuboid). The 6-DoF pose can be related to the camera's position and / or orientation or any suitable reference point or reference plane. The relative dimensions can be indicated by one or more values corresponding to the aspect ratio of the object's enclosing cuboid. In one embodiment, the reference... Figure 1 The 6-DoF pose and dimension 134 are visually represented by the surrounding cuboid, and the relative dimensions in the 6-DoF pose and dimension 134 are represented by "[W:H:L]", which indicates the ratio of the width (e.g., "W") to the height (e.g., "H") to the length (e.g., "L") of the surrounding cuboid. In some examples, the relative dimensions of the surrounding cuboid are represented by "[W:H:L]", "[W / H / L]", and / or any suitable notation indicating the ratio of the width (e.g., "W") to the height (e.g., "H") to the length (e.g., "L") of the surrounding cuboid.
[0097] The system 102 for object pose estimation can be specific to one or more object categories. The system 102 for object pose estimation can be trained with training data such that it is specific to the object category (e.g., the training data includes images depicting objects of that category). As an illustrative example, the system 102 for object pose estimation is trained to be specific to a class of objects called “mugs,” wherein the system 102 can calculate the 6-DoF pose and relative size of objects depicted in an image belonging to the object category called “mugs,” which can include “mug” objects with different colors, sizes, orientations, and / or variations thereof. In some embodiments, one or more neural networks of the system 102 for object pose estimation can be replicated and trained using training data such that the system 102 is dedicated to objects of one or more categories.
[0098] As an illustrative example, the first set of neural networks in the system 102 for object pose estimation is trained using training data specific to a first class of objects, and the second set of neural networks in the system 102 for object pose estimation is trained using training data specific to a second class of objects. The system 102 for object pose estimation can calculate the 6-DoF pose and relative size of an object in an image that belongs to either the first or second class of objects. Continuing this example, the system for object pose estimation can acquire an image depicting an object in an object class (e.g., the first class), determine one or more features at least in part based on the image, and predict a set of values based on the one or more features that at least indicate the position and relative size of the object in the image. Further continuing this example, the system for object pose estimation can also acquire another image depicting a different object in a different class of objects (e.g., the second class), determine another or more features at least in part based on the other image, and predict another set of values based on the other or more features that at least indicate another position and another relative size of the different object in the other image.
[0099] One or more neural networks and / or various other components of the system 102 for object pose estimation can be copied, modified and / or trained using any suitable training data, such that the system 102 for object pose estimation can calculate the 6-DoF pose and relative size of an object in an image that belongs to any suitable object category.
[0100] One or more systems (such as a training framework) can train one or more neural networks for object pose estimation in system 102. One or more systems may acquire training data from one or more datasets or other systems and utilize that training data to train one or more neural networks for object pose estimation in system 102. The training data may include images showing the 6-DoF pose of the object depicted in the illustrated image and the relative dimensions of its enclosing cuboid. The training data may include images and ground truth data (e.g., indicating the 6-DoF pose of the object depicted in the image and the relative dimensions of its enclosing cuboid). The training data may include images, where each image is associated with a 2D point (e.g., a vertex), centroid, and relative dimensions of the enclosing cuboid of the object depicted in the image.
[0101] In one embodiment, one or more systems utilize heatmaps of the center point and other key points in a point-by-point manner, respectively. and The penalty-reduced focal losses can be represented by the following function, although any variations thereof may be used:
[0102]
[0103] in Y represents the predicted score at the heatmap location represented by (i, j). ij This represents the ground truth value assigned to each point by the Gaussian kernel. In one embodiment, N represents the number of center points in the image, and α and β represent hyperparameters of the focus loss. In some examples, α = 2 and β = 4, although the values can be any suitable values.
[0104] One or more systems can use L1 loss to exploit the... The center offset loss is represented. The predicted offset can be represented by p, the ground truth center point can be represented by R, and the output stride can be represented by R. The low-resolution equivalent of p can be... The offset loss can be defined by the following formula, although any variations thereof can be used:
[0105]
[0106] One or more systems can be calculated, at least in part, based on one or more formulas and / or processes (as described herein). The keypoint offset loss is represented. One or more systems can use L1 loss relative to label (e.g., ground truth) values to compute the 2D bounding box size loss (by...). (represented), key point displacement loss (by) (represented) and relative size loss (by) express).
[0107] One or more systems can compute one or more neural networks of system 102 for object pose estimation. The total loss, which can be a weighted combination of one or more loss terms, can be expressed by the following formula, although any variations thereof may be used:
[0108]
[0109] in Or any suitable value, and λ_bbox = 0.1, or any suitable value. One or more systems can train one or more neural networks for object pose estimation system 102 by computing losses using at least one or more loss functions (such as those described herein) and updating one or more weights, biases, and / or structural connections of one or more neural networks to minimize the loss. One or more systems can continuously compute the loss of one or more neural networks and update one or more neural networks until the computed loss is below a defined threshold, which can be any suitable value. System 102 for object pose estimation can be trained such that the computed loss of one or more neural networks for object pose estimation system 102 is below the defined threshold.
[0110] Figure 2 Example 200 of 6-DoF pose and relative size according to at least one embodiment is shown. The 6-DoF pose and relative size can be consistent with those described herein. A system for object pose estimation can process an image to calculate the 6-DoF pose and relative size of an object depicted in the image, which can be visualized via 6-DoF pose and size visualization 202.
[0111] In one embodiment, 6-DoF pose refers to 3D position and orientation. The 6-DoF pose of an object can be represented by a 3D bounding box (also called a bounding cuboid) or other suitable representation. The 3D bounding box can be indicated by the vertex coordinates of the 3D bounding box. In some examples, the 3D bounding box is visualized on a 2D image and defined by the vertex coordinates of the 3D bounding box within the 2D image.
[0112] The relative dimensions of a 3D bounding box can refer to a set of values indicating the size of the 3D bounding box (e.g., the width, length, and / or height of the 3D bounding box) relative to each other. In one embodiment, the relative dimensions of a 3D bounding box include width, height, and length values that form the width-to-height-to-length ratio of the 3D bounding box (e.g., width, height, and length values). In some examples, the width, height, and length values of the relative dimensions represent the width, height, and length values of the 3D bounding box relative to each other, respectively. The relative dimensions of a 3D bounding box can be represented by the aspect ratio of the 3D bounding box, which indicates the ratio of the width to the height to the length of the 3D bounding box. In various embodiments, the height value is set to a value of 1, and the width and length values are calculated relative to the height value of 1. In various embodiments, any suitable value of the relative dimensions (e.g., width, height, and / or length values) is set to a value of 1, where the remaining two values are calculated relative to the suitable value set to a value of 1. The relative dimensions can be represented by any suitable set of values corresponding to the dimensions of the 3D bounding box and / or the object.
[0113] Systems for object pose estimation can acquire images depicting an object and determine its 6-DoF pose and relative dimensions. (Reference) Figure 2 As an illustrative example, the image depicts a car object, and the system used for object pose estimation determines the car object's 6-DoF pose and relative dimensions. The object's 6-DoF pose and relative dimensions can be visualized using 6-DoF pose and dimension visualization 202.
[0114] In one embodiment, 6-DoF pose and size visualization 202 is a visualization of the 6-DoF pose and relative size of an object in a 2D image. 6-DoF pose and size visualization 202 may include a visualization of a 3D bounding box indicating the 6-DoF pose of the object, and relative size values corresponding to the dimensions of the 3D bounding box. (Reference) Figure 2 As an illustrative example, for an image depicting a car object, the 6-DoF pose and size visualization 202 includes a visualization of a 3D bounding box indicating the 6-DoF pose of the car object, and includes a width value of 2.2, a height value of 1, and a length value of 4.7 (e.g., in...). Figure 2 The relative size values described in the figure are [2.2 / 1 / 4.7], which indicate that the aspect ratio of the 3D bounding box of the car object is 2.2:1:4.7.
[0115] It should be noted that while the example embodiments described herein may relate to six degrees of freedom (6DOF) pose, the techniques described herein are applicable to any suitable pose representation. Systems for object pose estimation can determine the pose of an object from an image, where the pose may correspond to any suitable degree of freedom (e.g., 8DOF, 7DOF, 5DOF, 4DOF, 3DOF, and / or variations thereof), which may correspond to any suitable translation and / or rotation.
[0116] Figure 3 An example 300 of the result of a system for object pose estimation according to at least one embodiment is shown. The system for object pose estimation can process input 302 to compute output 304 using one or more procedures such as those described herein.
[0117] Input 302 can be an input image and can depict one or more objects. See [reference needed] for an illustrative example. Figure 3Input 302 depicts four objects, referred to as a category called a mug. In one embodiment, a category is a classification of objects, where objects categorized into that category can share various characteristics. As an illustrative example, a category called a car could include instances of car objects with different colors, sizes, having or not having specific features and / or variations thereof. A system for object pose estimation can process input 302 and calculate the 6-DoF pose of each object depicted in input 302 and its relative dimensions to the enclosing cuboid to determine output 304.
[0118] Output 304 may include the 6-DoF pose of the object depicted in input 302 and an indication of the relative dimensions of its enclosing cuboid. The 6-DoF pose and relative dimensions can be indicated by values of the enclosing cuboid and relative dimensions. In some examples, the system visualizes the 6-DoF pose and relative dimensions of the object by overlaying the values of the enclosing cuboid and relative dimensions onto the object depicted in the image. See [reference needed] for an illustrative example. Figure 3 Output 304 includes a visualization of the enclosing cuboid of the object depicted in input 302 and the relative size values of the enclosing cuboid.
[0119] One or more systems may use a batch size of 32 or any suitable value, employing one or more GPUs (such as NVIDIA's V-100 GPU) to train one or more neural networks for object pose estimation for 140 epochs or any suitable number of epochs, starting with pre-trained weights from a network such as ImageNet, although in some embodiments, pre-trained weights are not used. Data augmentation may include random flipping, scaling, cropping, color jittering, and / or variations thereof. One or more systems may use an optimizer, such as the Adam optimizer with any suitable learning rate (such as an initial learning rate of 2.5e-4), and may decrease by a factor of 10 over 90 to 120 epochs or any suitable number of epochs. In one embodiment, one or more systems may require approximately 36 hours to train a single class (e.g., using training images between 8k and 32k depending on the class). On a GPU such as NVIDIA's GTX 1080Ti GPU, the inference speed may be approximately 10 frames per second (fps).
[0120] One or more systems can be trained using a dataset such as the Objectron dataset, although any suitable dataset can be used. The dataset can include 15k annotated video clips with more than 4M annotated frames, or any appropriate number of annotated video clips and / or frames. Objects can come from nine categories: bicycle, book, bottle, camera, cereal box, chair, cup, laptop, and shoe, although any suitable category can be used. In one embodiment, each object is annotated with its 3D bounding cuboid, which describes the object's position and orientation relative to the camera, as well as the cuboid's dimensions. For each video recording, the camera may move around the stationary object, capturing it from different angles. Additional metadata may include camera pose, sparse point cloud, and surface planes, the latter assuming the object is located on a ground plane, which may introduce an absolute scaling factor.
[0121] For training, to improve efficiency, one or more systems can extract frames by temporally downsampling the original video at fps (such as 15fps). For testing, one or more systems can evaluate the top 5000 test samples in each category of the dataset, or any suitable number of test samples that can be randomly shuffled. In some examples, the cup category includes both cups and mugs, where the former has no handle. Therefore, one or more systems can manually distinguish these by training separate networks for each. One or more systems can rotate certain ground reality bounding boxes by 180 degrees to ensure consistent orientation.
[0122] For symmetrical objects like cups, one or more systems can generate a set of {y1, ..., y2}. |θ| The system represents multiple ground-based labels, which, during this training phase, are rotated around an axis of symmetry |θ|, where |θ| = 12 or any suitable value. One or more systems can compute the values generated by... The symmetric loss is represented by, where Indicates prediction, This indicates asymmetric loss.
[0123] One or more systems may utilize various metrics of the results from the system used for object pose estimation. In one embodiment, to evaluate 3D detection and object size estimation, one or more systems utilize the average precision (AP) of a 3D IoU metric with a threshold of 50%, or any suitable metric and / or threshold. A 2D pixel projection error metric can be calculated as the mean-normalized distance between the projections of keypoints in the 3D bounding box of a given estimated pose and the ground-based pose. For viewpoint estimation, one or more systems may utilize the AP for azimuth and elevation angles, with thresholds of 15° and 10°, respectively, or any suitable values. For symmetrical object categories (e.g., bottles and cups), one or more systems may rotate the ground-based bounding box N times (e.g., N = 100) along the axis of symmetry and evaluate the prediction with respect to each rotation instance. In one embodiment, the reported number is the instance that maximizes 3D IoU or minimizes 2D pixel projection error, respectively. Although the cup category may include asymmetrical mug instances, one or more systems may treat them as symmetrical. For ablation studies of relative size prediction, one or more systems can utilize the mean relative size error, which calculates the relative error of all predictions of the relative size, by... It means that among them This represents a prediction, and y i It represents the actual ground conditions, although any appropriate error can be utilized.
[0124] Figure 4 Example 400 of the result values of a system for object pose estimation according to at least one embodiment is shown. In one embodiment, Figure 4 Results for one or more class-level 6-DoF pose and size estimation tasks are described. One or more systems can be compared to one or more systems such as one-step MobilePose and two-step networks. One or more systems can utilize datasets such as the Objectron dataset. Figure 4 The system can depict the results of 3D IoU, 2D pixel projection error, and azimuth and elevation angles. The system for object pose estimation outperforms MobilePose on all metrics, while the two-step method achieves better performance on 2D correlation metrics but lags behind on 3D IoU metrics.
[0125] Figure 5 Another example 500 of the resulting values of a system for object pose estimation according to at least one embodiment is shown. In one embodiment, Figure 5The results of ablation experiments on different keypoint representations are depicted. Systems for object pose estimation can utilize heatmaps and displacement representations for 2D keypoint detection. One or more systems can utilize ablation experiments to compare various ways of utilizing this representation, such as, for example, although any of its variations can be used: 1) displacement, ignoring the heatmap; 2) heatmap, ignoring displacement; 3) heatmap and displacement; 4) distance, where a heuristic is used to select points to use from either displacement or heatmap; 5) sampling, where a Gaussian mixture model is applied to heatmap peak estimation, and displacement predictions for each keypoint and multiple points (represented by N (e.g., N=20)) are sampled to obtain possible pose distributions. Reference Figure 5 As shown, a system for object pose estimation outperforms one or more other systems by utilizing heatmaps and displacements.
[0126] Figure 6 Another example 600 of the resulting values of a system for object pose estimation according to at least one embodiment is shown. In one embodiment, Figure 6 The results of ablation experiments regarding the prediction of cuboid dimensions are described. Figure 6 Ablation experiments of convGRU for predicting relative cuboid dimensions can be depicted. One or more systems can be compared to variations of systems used for object pose estimation, such as, for example, although any of its variations can be utilized: 1) oracle, which can refer to a system capable of accessing ground-real 3D aspect ratios (e.g., relative dimensions); 2) keypoint lifting, where the final pose can be retrieved using only 2D projected cuboid keypoints using one or more post-processing steps; 3) without convGRU, where the convGRU layer is removed from the system used for object pose estimation; and 4) with convGRU, also referred to as a system used for object pose estimation. In one embodiment, Figure 6 The results using 3D IoU metrics are depicted. In some examples, the maximum improvement is calculated for two specific categories (e.g., books and laptops), which can be complex due to different 3D aspect ratios (e.g., whether the laptop is open or closed). When using PnP algorithms (such as simplified EPnP variants), one or more systems can determine this performance degradation, indicating that predicting the relative size of the category-level pose estimate from monocular RGB input is a complete process.
[0127] Figure 7 Example 700 illustrating key point representations according to at least one embodiment is shown. In one embodiment, Figure 7 Two different keypoint representations are depicted, as described herein. The cycle can be determined by this displacement, and the heatmap keypoints can be overlaid with shadows corresponding to their intensity. In one embodiment, reference... Figure 7On the left, the heatmap is more accurate when the corners of the bounding box are visible and aligned with the object, while on the right, the displacement is better when the corners of the bounding box are not tightly fitted to the target surface (e.g., the top of a laptop).
[0128] Figure 8 Another example 800 of the results of a system for object pose estimation according to at least one embodiment is shown. In one embodiment, Figure 8 One or more enclosing cuboids are depicted. Cuboid 802 may represent a ground reality cuboid, cuboid 804 may represent a system for object pose estimation cuboids without a feature association module (e.g., convGRU), and cuboid 806 may represent a system for object pose estimation cuboids with such a module.
[0129] In some examples, estimating the thickness of a thin object is complex when viewed from an angle (e.g., an azimuth angle close to 90°). In one embodiment, Figure 8 This describes the ability of a convGRU (e.g., cuboid 806) to retrieve the 3D aspect ratio (e.g., relative size) of an object when comparing it without a convGRU (e.g., cuboid 804), even if the 2D keypoints may appear accurate. In one embodiment, one or more systems calculate a 3D IoU (↑) value of 0.5059 (with convGRU) versus 0.3204 (without convGRU), although the value can be any suitable value. In one embodiment, one or more systems evaluate the system for object pose estimation with and without convGRU on a relative aspect ratio metric, although the value can be any suitable value, resulting in an error of 0.38 (without convGRU) versus 0.34 (with convGRU), indicating that convGRU helps retrieve the cuboid aspect ratio. Improvements for the book and notebook categories might be values of 0.80 versus 0.68, and 0.92 versus 0.64, although the value can be any suitable value.
[0130] In some examples, one or more systems utilize systems for object pose estimation within various robotic systems. Systems for object pose estimation can be used for robotic grasping tasks. In some embodiments, a robotic gripper is used in conjunction with a robot arm, and one or more systems use a camera mounted on another arm of the robot to capture images. In one embodiment, a ReFlex TakkTile2 gripper and a Baxter robot, or any suitable robotic hardware, are used. When an object is detected and its pose is estimated (e.g., via the system for object pose estimation), the gripper can be moved to a position intended to be slightly above the object, after which the gripper can be closed and lifted a specific distance (e.g., 15 cm). The robotic system can grasp previously unseen instances from each of three object categories: cereal boxes, cups, and shoes. In one embodiment, all objects were successfully grasped in two attempts, with a 93.3% grasp rate on the first attempt.
[0131] It should be noted that while the various results and / or result values described herein can be indicated by specific results and / or result values, the results and / or result values can be any suitable results and / or result values, which may depend on the conditions and / or variations thereof used to determine the results and / or result values. Variations in results and / or result values are within the scope of this disclosure.
[0132] Systems for object pose estimation can perform single-step, class-level 6-DoF pose prediction for previously unseen object instances. These systems may not require various 3D models of instances during training and / or testing, and training may not require synthetic data. For 2D keypoint detection, systems for object pose estimation can mitigate uncertainty by leveraging a combination of displacement and heatmap representations. Systems for object pose estimation can estimate the relative dimensions of a 3D bounding box. To further improve accuracy, systems for object pose estimation can utilize convGRU sequence feature associations. Systems for object pose estimation can be evaluated using datasets such as the Objectron dataset, in conjunction with one or more other systems. Systems for object pose estimation can be leveraged in a variety of contexts, including robotic grasping tasks and various other real-world applications. Systems for object pose estimation can be class-specific, combined with differential rendering, and utilize post-iterative refinement.
[0133] Figure 9An example of a process 900 for a system for object pose estimation according to at least one embodiment is illustrated. In at least one embodiment, part or all of process 900 (or any other process described herein, or variations and / or combinations thereof) is executed under the control of one or more computer systems configured with computer-executable instructions and implemented as code (e.g., computer-executable instructions, one or more computer programs, or one or more application programs) jointly executed on one or more processors by hardware, software, or a combination thereof. In at least one embodiment, the code is stored in the form of a computer program on a computer-readable storage medium comprising a plurality of computer-readable instructions executable by one or more processors. In at least one embodiment, the computer-readable storage medium is a non-transitory computer-readable medium. In at least one embodiment, at least some of the computer-readable instructions available for executing process 900 are not stored using only transient signals (e.g., propagating transient electrical or electromagnetic transmissions). In at least one embodiment, the non-transitory computer-readable medium does not necessarily include non-transitory data storage circuitry (e.g., buffers, caches, and queues) within a transient signal transceiver. In at least one embodiment, process 900 is executed at least partially on a computer system such as those described elsewhere in this disclosure. In one embodiment, process 900 is performed by a system for object pose estimation.
[0134] In at least one embodiment, the system performing at least a portion of process 900 includes executable code for acquiring 902 an image depicting an object of the first category. In one embodiment, the image is an image of any suitable image format (e.g., red-green-blue (RGB) image, black / white (B / W) image, grayscale image, RGB-D image, and / or variations thereof), which may be stored or otherwise encoded using any suitable image file format that encodes image data (e.g., bitmap image file, JPEG (Joint Image Experts Group) file, SVG (Scalable Vector Graphics) file, and / or variations thereof). The image may be a video frame. Any suitable system can be used to capture the image, such as vehicle systems (e.g., autonomous vehicles, semi-autonomous vehicles), medical devices (e.g., medical imaging equipment), autonomous devices (e.g., robots), and / or any suitable system.
[0135] The image may depict objects of the first category. The image may depict objects in any suitable environment or background. The first category may correspond to any suitable category. In some examples, a category is defined as a family of similar objects; for example, a category called "mug" may include instances of mugs with different colors, sizes, handles or not, and / or variations thereof. The image may also depict one or more other objects that may or may not belong to the first category.
[0136] In at least one embodiment, a system performing at least a portion of process 900 includes executable code for generating 904 one or more features at least partially based on an image. The system may utilize neural networks, such as Deep Aggregation (DLA)34 networks with incorporating upsampling, where hierarchical aggregation connections can be enhanced by deformable convolutional layers to generate one or more features from the image. One or more features (also referred to as a set of features) may comprise one or more feature maps at one or more resolutions. In some examples, the system generates multiple intermediate feature maps at different resolutions, ranging from H / 4×W / 4 to H / 32×W / 32, or any suitable resolution, which may be aggregated into a single output with a resolution of H / 4×W / 4, or any suitable resolution, where H represents the height of the image (e.g., measured in pixels) and W represents the width of the image (e.g., measured in pixels).
[0137] In at least one embodiment, a system performing at least a portion of process 900 includes executable code for processing the one or more features using one or more neural networks to determine at least one or more coordinate values and one or more relative size values corresponding to the object. The one or more neural networks may include one or more convGRU networks. The system may use one or more neural networks to process one or more features to determine a first set of data corresponding to the object. The first set of data may include an object center heatmap, an object center offset, and a 2D bounding box size, which may correspond to the object and / or the object's 2D bounding box. In some examples, the first set of data includes a first set of values (e.g., color values) from the object center heatmap. The object center heatmap may be referred to as the first set of heatmaps.
[0138] The system can compute a second set of data based at least in part on one or more features and the determination of a first set of data. The system can use one or more neural networks to compute the second set of data. The system can compute the second set of data based on the determination of the first set of data by utilizing one or more hidden states associated with and / or utilized in the determination of the first set of data. A hidden state can refer to a representation of one or more inputs of the neural network, which can be processed by one or more processes of the neural network. The system can cause one or more neural networks to compute the second set of data using one or more hidden states associated with the determination of the first set of data. The second set of data may include a keypoint heatmap, keypoint offsets, and XY displacements, which may correspond to an object and / or a 3D bounding box of the object. In some embodiments, the second set of data includes a second set of values (e.g., color values) of the keypoint heatmap. The keypoint heatmap may be referred to as the second set of heatmaps. The XY displacements may include a set of vectors corresponding to the vertices of the bounding box of the object.
[0139] The system can calculate a set of values corresponding to the relative dimensions of an object, at least in part, based on calculations of a second set of data. The relative dimensions of the object may refer to the relative dimensions of the object's 3D bounding box. The system can use one or more neural networks to calculate this set of values. The system can calculate the set of values based on calculations of the second set of data by utilizing one or more hidden states associated with and / or used in the calculations of the second set of data. The system can cause one or more neural networks to use one or more hidden states associated with the calculations of the second set of data to calculate the set of values. This set of values may include width, height, and length values, which can form the ratio of the width to the height to the length of the object's 3D bounding box (e.g., the ratio of the width value to the height value to the length value).
[0140] The system can determine one or more coordinate values based on a first set of data and a second set of data. The system can apply pooling operations (e.g., 3×3 max pooling) to a heatmap of the 2D object's center (e.g., an object center heatmap) to search for all local maxima within a window. For each detected center point, the displacement-based keypoint location can be indicated by the keypoint coordinate offset below the center point. The system can extract heatmap-based keypoint locations by determining high-confidence peaks in the corresponding heatmap (e.g., a keypoint heatmap) within the boundary of the 2D object's bounding box. The system can adjust the keypoint location estimate based on the offset (e.g., the offset in a keypoint offset). The system can determine one or more coordinate values indicating the keypoint location. Keypoints can correspond to vertices of the object's 3D bounding box. One or more coordinate values can indicate the coordinates of the keypoint location within the image. In some embodiments, this set of values forms one or more relative size values. Further information regarding the determination of one or more coordinate values and one or more relative size values can be found in... Figure 1 It was found in the description.
[0141] In at least one embodiment, the system performing at least a portion of process 900 includes executable code for processing one or more coordinate values and one or more relative size values using one or more algorithms to calculate the six-degree-of-freedom (6DOF) pose of an object. The one or more algorithms may include one or more PnP algorithms. In some embodiments, the one or more algorithms include one or more neural network models, algorithms, and / or variations thereof. In some embodiments, the system acquires a set of data corresponding to an image capture device that captures images (e.g., camera intrinsic parameters), which may be part of the system, and inputs this set of data into one or more algorithms. The system may enable one or more algorithms to process one or more coordinate values and / or one or more relative size values, wherein one or more algorithms may output the 6DOF pose of the object.
[0142] The 6DOF pose can be indicated by one or more values corresponding to the object's x-axis position, y-axis position, z-axis position, roll axis angle, pitch axis angle, and / or yaw axis angle. The 6DOF pose can be indicated by the coordinates of the vertices of the enclosing cuboid (e.g., the coordinates of the vertices of the enclosing cuboid within the image). The 6DOF pose can be related to the position and / or orientation of the camera (e.g., the camera that captured the image) or any suitable reference point or plane. One or more relative dimension values can be indicated by one or more values corresponding to the aspect ratio of the object's enclosing cuboid.
[0143] In some embodiments, the system (e.g., a system for object pose estimation) calculates the absolute scale based at least in part on one or more relative size values. The absolute scale of an object, also known as absolute size, can refer to the size of the object in the real world. In some examples, the absolute scale of an object corresponds to the size of the enclosing cuboid of the object in the real world. The system may acquire depth information to calculate the absolute scale of the object based on one or more relative size values.
[0144] For example, the system acquires depth information from an image and / or video capture device that captures the image, or other systems associated with that device (e.g., a depth sensor), and uses this depth information to scale one or more relative size values to calculate the absolute scale of the object. In various embodiments, the image and / or video capture device that captures the image is a stereo device (e.g., a stereo camera), where the system utilizes depth information determined based on one or more images captured by the device to scale one or more relative size values to calculate the absolute scale of the object. The system can calculate the absolute scale of the object in any suitable manner.
[0145] As an illustrative example, the system is associated with an image and / or video capture device that moves relative to an object and captures multiple images of the object. The image and / or video capture device may be moved by a robotic appendage or other suitable system. Continuing the example, absolute camera motion information is provided to the system, which may include information such as one or more translations and / or rotations of the device when multiple images are captured. The system may obtain or otherwise have absolute camera motion information provided from various systems associated with robotic appendages, inertial measurement units (IMUs), and / or variations thereof. Further continuing the example, the system utilizes multiple images and absolute camera motion information to process one or more relative size values to calculate an absolute scale of the object. In at least one embodiment, one or more neural networks of the system are trained using images depicting objects of approximately the same size and are trained to predict the absolute scale by regression or otherwise, with one or more neural networks outputting the absolute scale of the object in addition to or instead of one or more relative size values.
[0146] In some examples, the system is associated with one or more robotic systems that utilize the 6DOF pose of an object to perform a robotic grasping task. A robotic grasping task can refer to one or more processes and / or operations in which the robotic system grasps an object (e.g., via a gripper or other robotic appendage associated with the robotic system) and / or moves the object to one or more locations. One or more robotic systems may be located in an environment where the object can be accessed. The system can enable one or more robotic systems to perform object-related robotic grasping tasks using 6DOF poses. The system can send or otherwise transmit data indicating 6DOF poses to one or more robotic systems. In some embodiments, the system is part of and / or has access to one or more robotic systems.
[0147] One or more robotic systems can utilize 6DOF poses to grasp objects. One or more robotic systems can utilize 6DOF poses to determine how to grasp the object. In various embodiments, one or more robotic systems process 6DOF poses to calculate a specific configuration of the robotic gripper associated with the one or more robotic systems, such that the gripper can grasp the object. One or more robotic systems can then grasp the object (e.g., via the gripper) and perform a robotic grasping task, which may involve moving the grasped object (e.g., via the gripper) to one or more locations.
[0148] Systems for object pose estimation can be used in conjunction with any suitable robotic system, such as excavators, garbage trucks, vehicles with robotic appendages, factory robots, recycling center robots, robotic assistants, warehouse robots, and / or variations thereof. As an illustrative example, one or more systems of an excavator may utilize the system for object pose estimation to process images and / or videos captured in association with the excavator to determine the pose of an object depicted in the images and / or videos, wherein one or more systems of the excavator may utilize the determined pose to configure the excavator so that it is capable of grasping, transporting, and / or excavating objects. Systems for object pose estimation can be similarly used to process images and / or videos captured in connection with garbage trucks, vehicles with robotic attachments, factory robots, recycling center robots, robotic assistants, warehouse robots, and / or their variants, to determine the poses of various objects depicted in the images and / or videos. One or more of these systems can utilize the determined poses to enable them to grasp, transport, manipulate, and / or move various objects. Examples of robotic systems that can be used in conjunction with systems for object pose estimation are available. Figures 13A-13D Found it.

[0278] In at least one embodiment, conventional ADAS systems may be prone to generating false alarms, which can be annoying and distracting to the driver, but are generally not catastrophic because conventional ADAS systems warn the driver and allow the driver to determine whether a safe situation truly exists and take appropriate action. In at least one embodiment, in the event of conflicting results, the vehicle 1300 itself decides whether to follow the result of the main computer or the auxiliary computer (e.g., the first or second controller of controller 1336). For example, in at least one embodiment, ADAS system 1338 may be a backup and / or auxiliary computer for providing perception information to a backup computer rationality module. In at least one embodiment, the backup computer rationality monitor may run redundant software on hardware components to detect faults in perception and dynamic driving tasks.

[0279] In at least one embodiment, the master computer may be configured to provide a confidence score to the supervisory MCU to indicate the master computer's confidence in the selected result. In at least one embodiment, if the confidence score exceeds a threshold, the supervisory MCU may follow the master computer's instructions regardless of whether the auxiliary computer provides conflicting or inconsistent results. In at least one embodiment, if the confidence score does not meet the threshold, and if the master computer and the auxiliary computer indicate different results (e.g., conflicting), the supervisory MCU may arbitrate between the computers to determine the appropriate result.
[0280] In at least one embodiment, the supervisory MCU may be configured to run a neural network trained and configured to determine, at least in part, the conditions under which the auxiliary computer provides a false alarm based on outputs from a host computer and an auxiliary computer. In at least one embodiment, the neural network in the supervisory MCU may learn when the outputs of the auxiliary computer can be trusted and when they cannot. For example, in at least one embodiment, when the auxiliary computer is a RADAR-based FCW system, the neural network in the supervisory MCU may learn when the FCW system recognizes a metallic object that is not actually dangerous, such as a drain grating or manhole cover that would trigger an alarm. In at least one embodiment, when the auxiliary computer is a camera-based LDW system, the neural network in the supervisory MCU may learn to override the LDW when a cyclist or pedestrian is present and lane departure is actually the safest operation. In at least one embodiment, the supervisory MCU may include at least one of a DLA or GPU suitable for running a neural network with associated memory. In at least one embodiment, the supervisory MCU may include and / or be included as a component of one or more SoC 1304s.
[0281] In at least one embodiment, the ADAS system 1338 may include an auxiliary computer that performs ADAS functions using conventional computer vision rules. In at least one embodiment, the auxiliary computer may use classic computer vision rules (if-then), and the presence of a neural network in the supervisory MCU can improve reliability, security, and performance. For example, in at least one embodiment, diverse implementations and intentional non-identity make the entire system more fault-tolerant, especially for failures caused by software (or software-hardware interface) functionality. For example, in at least one embodiment, if a software vulnerability or bug exists in the software running on the host computer, and different software code running on the auxiliary computer provides consistent overall results, the supervisory MCU can more confidently assume that the overall result is correct and that the vulnerability in the software or hardware on the host computer will not lead to a significant error.
[0282] In at least one embodiment, the output of the ADAS system 1338 can be input to the perception module and / or the dynamic driving task module of the host computer. For example, in at least one embodiment, if the ADAS system 1338 indicates a forward collision warning due to an object directly ahead, the perception block can use this information when identifying the object. In at least one embodiment, as described herein, the assistance computer can have its own neural network trained to reduce the risk of false alarms.

As previously mentioned, this task can be accomplished via proxy circuitry 1825 representing cache 1838 and graphics memory 1833(1)-1833(M) (e.g., sending updates related to the modification / access of cache lines on processor caches 1862A-1862D, 1856 to cache 1838 and receiving updates from cache 1838).
[0332] In at least one embodiment, a set of registers 1845 stores context data of threads executed by graphics processing engines 1831(1)-1831(N), and context management circuitry 1848 manages the thread context. For example, context management circuitry 1848 can perform save and restore operations to save and restore the context of individual threads during context switching (e.g., saving the first thread and storing the second thread so that the second thread can be executed by the graphics processing engine). For example, during context switching, context management circuitry 1848 can store the current register value in a designated area of memory (e.g., identified by a context pointer). The register value can then be restored when returning to the context. In at least one embodiment, interrupt management circuitry 1847 receives and processes interrupts received from system devices.
[0333] In at least one embodiment, MMU 1839 translates virtual / effective addresses from graphics processing engine 1831 into real / physical addresses in system memory 1814. In at least one embodiment, accelerator integrated circuit 1836 supports multiple (e.g., 4, 8, 16) graphics accelerator modules 1846 and / or other accelerator devices. In at least one embodiment, graphics accelerator module 1846 may be dedicated to a single application executing on processor 1807, or may be shared among multiple applications. In at least one embodiment, a virtualized graphics execution environment is presented, wherein resources of graphics processing engines 1831(1)-1831(N) are shared with multiple applications or virtual machines (VMs). In at least one embodiment, resources may be subdivided into “slices” based on processing requirements and priorities associated with VMs and / or applications, which are allocated to different VMs and / or applications.
[0334] In at least one embodiment, the accelerator integrated circuit 1836 acts as a bridge to the system of the graphics acceleration module 1846 and provides address translation and system memory caching services. Additionally, in at least one embodiment, the accelerator integrated circuit 1836 can provide virtualization facilities for the host processor to manage the virtualization, interrupt, and memory management of the graphics processing engines 1831(1)-1831(N).
[0335] In at least one embodiment, since the hardware resources of the graphics processing engines 1831(1)-1831(N) are explicitly mapped to the real address space seen by the host processor 1807, any host processor can directly address these resources using valid address values. In at least one embodiment, a function of the accelerator integrated circuit 1836 is to physically separate the graphics processing engines 1831(1)-1831(N) so that they appear as independent units to the system.
[0336] In at least one embodiment, one or more graphics memories 1833(1)-1833(M) are coupled to each graphics processing engine 1831(1)-1831(N), and N = M. In at least one embodiment, the graphics memories 1833(1)-1833(M) store instructions and data processed by each graphics processing engine 1831(1)-1831(N). In at least one embodiment, the graphics memories 1833(1)-1833(M) may be volatile memory, such as DRAM (including stacked DRAM), GDDR memory (e.g., GDDR5, GDDR6), or HBM, and / or may be non-volatile memory, such as 3DXPoint or Nano-RAM.
[0337] In at least one embodiment, to reduce data traffic on the high-speed link 1840, a biasing technique can be used to ensure that the data stored in the graphics memory 1833(1)-1833(M) is the data most frequently used by the graphics processing engine 1831(1)-1831(N), and preferably data that the cores 1860A-1860D do not use (or at least do not use frequently). Similarly, in at least one embodiment, the biasing mechanism attempts to keep the data needed by the cores (and preferably not the graphics processing engine 1831(-1)-1831(N)) in the caches 1862A-1862D, 1856 and system memory 1814.
[0338] Figure 18C Another exemplary embodiment is shown, in which the accelerator integrated circuit 1836 is integrated within the processor 1807. In this embodiment, the graphics processing engines 1831(1)-1831(N) communicate directly with the accelerator integrated circuit 1836 via a high-speed link 1840 through interfaces 1837 and 1835 (which may also be any form of bus or interface protocol). In at least one embodiment, the accelerator integrated circuit 1836 can perform operations related to... Figure 18B The described operation is similar to that of the accelerator integrated circuit. However, due to its close proximity to the coherence bus 1864 and caches 1862A-1862D, 1856, it may have higher throughput. In at least one embodiment, the accelerator integrated circuit supports different programming models, including a dedicated process programming model (without graphics acceleration module virtualization) and a shared programming model (with virtualization), which may include a programming model controlled by the accelerator integrated circuit 1836 and a programming model controlled by the graphics acceleration module 1846.
[0339] In at least one embodiment, graphics processing engines 1831(1)-1831(N) are dedicated to a single application or process under a single operating system. In at least one embodiment, a single application can funnel requests from other applications to graphics processing engines 1831(1)-1831(N), thereby providing virtualization within a VM / partition.
[0340] In at least one embodiment, graphics processing engines 1831(1)-1831(N) can be shared by multiple VM / application partitions. In at least one embodiment, the shared model can use a hypervisor to virtualize graphics processing engines 1831(1)-1831(N) to allow each operating system to access them. In at least one embodiment, for a single-partition system without a hypervisor, the operating system owns graphics processing engines 1831(1)-1831(N). In at least one embodiment, the operating system can virtualize graphics processing engines 1831(1)-1831(N) to provide access to each process or application.
[0341] In at least one embodiment, the graphics acceleration module 1846 or the individual graphics processing engine 1831(1)-1831(N) uses a process handle to select a process element. In at least one embodiment, the process element is stored in system memory 1814 and can be addressed using the effective address to real address translation techniques described herein. In at least one embodiment, the process handle may be an implementation-specific value provided to the host process when registering its context with the graphics processing engine 1831(1)-1831(N) (i.e., invoking system software to add the process element to the process element linked list). In at least one embodiment, the lower 16 bits of the process handle may be the offset of the process element in the process element linked list.
[0342] Figure 18DAn exemplary accelerator integration slice 1890 is illustrated. In at least one embodiment, a "slice" includes a designated portion of the processing resources of an accelerator integrated circuit 1836. In at least one embodiment, the application is an effective address space 1882 in system memory 1814, which stores process element 1883. In at least one embodiment, process element 1883 is stored in response to a GPU call 1881 from an application 1880 executing on processor 1807. In at least one embodiment, process element 1883 contains the process state of the corresponding application 1880. In one embodiment, a job descriptor (WD) 1884 contained in process element 1883 may be a single job requested by the application, or it may contain a pointer to a job queue. In at least one embodiment, WD 1884 is a pointer to a job request queue in the effective address space 1882 of the application.
[0343] In at least one embodiment, the graphics acceleration module 1846 and / or the various graphics processing engines 1831(1)-1831(N) may be shared by all processes or a subset of processes in the system. In at least one embodiment, infrastructure may be included for setting process states and sending WD 1884 to the graphics acceleration module 1846 to begin operations in a virtualized environment.
[0344] In at least one embodiment, the dedicated process programming model is implementation-specific. In at least one embodiment, in this model, a single process owns either the graphics acceleration module 1846 or an individual graphics processing engine 1831. In at least one embodiment, when the graphics acceleration module 1846 is owned by a single process, the hypervisor initializes the accelerator integrated circuit for the owned partition, and when the graphics acceleration module 1846 is assigned, the operating system initializes the accelerator integrated circuit 1836 for the owned process.
[0345] In at least one embodiment, during operation, the WD acquisition unit 1891 in the accelerator integration slice 1890 acquires the next WD 1884, which includes instructions for work to be performed by one or more graphics processing engines of the graphics acceleration module 1846. In at least one embodiment, data from the WD 1884 may be stored in register 1845 and used by the MMU 1839, interrupt management circuitry 1847, and / or context management circuitry 1848, as shown. For example, one embodiment of the MMU 1839 includes segment / page roaming circuitry for accessing segment / page tables 1886 within the OS virtual address space 1885. In at least one embodiment, the interrupt management circuitry 1847 may process an interrupt event 1892 received from the graphics acceleration module 1846. In at least one embodiment, when performing graphics operations, a valid address 1893 generated by the graphics processing engines 1831(1)-1831(N) is translated into a real address by the MMU 1839.
[0346] In at least one embodiment, register 1845 is copied for each graphics processing engine 1831(1)-1831(N) and / or graphics acceleration module 1846, and said register 1845 may be initialized by a hypervisor or operating system. In at least one embodiment, each of these copied registers may be included in accelerator integration slice 1890. Exemplary registers that may be initialized by a hypervisor are shown in Table 1.
[0347]
[0348] Table 2 shows exemplary registers that can be initialized by the operating system.
[0349]
[0350] In at least one embodiment, each WD 1884 is specific to a particular graphics acceleration module 1846 and / or graphics processing engine 1831(1)-1831(N). In at least one embodiment, it contains all the information required for the graphics processing engine 1831(1)-1831(N) to complete its work, or it may be a pointer to a memory location where the application has set up a command queue for the work to be completed.
[0351] Figure 18E Additional details of an exemplary embodiment of the shared model are shown. This embodiment includes a hypervisor real address space 1898, in which a list of process elements 1899 is stored. In at least one embodiment, the hypervisor real address space 1898 can be accessed via a hypervisor 1896, which virtualizes the graphics acceleration module engine for operating system 1895.
[0352] In at least one embodiment, the shared programming model allows all processes or subsets of processes from all partitions or subsets of partitions in the system to use the graphics acceleration module 1846. In at least one embodiment, there are two programming models in which the graphics acceleration module 1846 is shared by multiple processes and partitions, namely, time-slice sharing and graphics-oriented sharing.
[0353] In at least one embodiment, in this model, the hypervisor 1896 owns the graphics acceleration module 1846 and makes its functionality available to all operating systems 1895. In at least one embodiment, for the graphics acceleration module 1846 to support virtualization through the hypervisor 1896, the graphics acceleration module 1846 may comply with certain requirements, such as (1) the job requests of the application must be autonomous (i.e., no state needs to be maintained between jobs), or the graphics acceleration module 1846 must provide a context saving and recovery mechanism, (2) the graphics acceleration module 1846 guarantees that the job requests of the application are completed within a specified amount of time, including any conversion errors, or the graphics acceleration module 1846 provides the ability to preempt job processing, and (3) when operating in a directed shared programming model, fairness between the processes of the graphics acceleration module 1846 must be ensured.
[0354] In at least one embodiment, application 1880 needs to make operating system 1895 system calls using the graphics acceleration module type, working descriptor (WD), permission mask register (AMR) value, and context save / restore region pointer (CSRP). In at least one embodiment, the graphics acceleration module type describes the target acceleration function for the system call. In at least one embodiment, the graphics acceleration module type can be a system-specific value. In at least one embodiment, the WD is specifically formatted for graphics acceleration module 1846 and can take the form of graphics acceleration module 1846 commands, valid address pointers to user-defined structures, valid address pointers to command queues, or any other data structure describing the work to be performed by graphics acceleration module 1846.
[0355] In at least one embodiment, the AMR value is the AMR state for the current process. In at least one embodiment, the value passed to the operating system is similar to that of the application that sets the AMR. In at least one embodiment, if the implementation of the accelerator integrated circuit 1836 (not shown) and the graphics acceleration module 1846 does not support the User Rights Mask Overwrite Register (UAMOR), the operating system may apply the current UAMOR value to the AMR value before passing the AMR in the hypervisor call. In at least one embodiment, the hypervisor 1896 may selectively apply the current Rights Mask Overwrite Register (AMOR) value before placing the AMR into the process element 1883. In at least one embodiment, CSRP is one of the registers 1845 containing the effective address of a region in the effective address space 1882 of the application for the graphics acceleration module 1846 to save and restore the context state. In at least one embodiment, this pointer is optional if it is not necessary to save state between jobs or when a job is preempted. In at least one embodiment, the context save / restore region may be fixed system memory.
[0356] Upon receiving a system call, operating system 1895 can verify that application 1880 has been registered and granted permission to use graphics acceleration module 1846. Then, in at least one embodiment, operating system 1895 uses the information shown in Table 3 to invoke hypervisor 1896.
[0357]
[0358] In at least one embodiment, upon receiving a hypervisor call, hypervisor 1896 verifies that operating system 1895 has been registered and granted permission to use graphics acceleration module 1846. Then, in at least one embodiment, hypervisor 1896 adds process element 1883 to a linked list of process elements of the corresponding graphics acceleration module 1846 type. In at least one embodiment, the process element may include the information shown in Table 4.
[0359]
[0360]
[0361] In at least one embodiment, the hypervisor initializes multiple accelerator integration slice 1890 registers 1845.
[0362] like Figure 18FAs shown, in at least one embodiment, a unified memory is used, which is addressable via a common virtual memory address space for accessing physical processor memories 1801(1)-1801(N) and GPU memories 1820(1)-1820(N). In this implementation, operations performed on GPUs 1810(1)-1810(N) utilize the same virtual / effective memory address space to access processor memories 1801(1)-1801(M) and vice versa, thereby simplifying programmability. In at least one embodiment, a first portion of the virtual / effective address space is allocated to processor memory 1801(1), a second portion to second processor memory 1801(N), a third portion to GPU memory 1820(1), and so on. In at least one embodiment, the entire virtual / effective memory space (sometimes referred to as the effective address space) is thus distributed across each of processor memory 1801 and GPU memory 1820, thereby allowing any processor or GPU to access that memory using a virtual address mapped to any physical memory.
[0363] In at least one embodiment, the bias / coherence management circuitry 1894A-1894E within one or more MMUs 1839A-1839E ensures cache coherence between one or more host processors (e.g., 1805) and the cache of the GPU 1810, and implements biasing techniques to indicate the physical memory in which certain types of data should be stored. In at least one embodiment, although in Figure 18F Several instances of bias / coherence management circuits 1894A-1894E are shown, but bias / coherence circuits can be implemented within the MMU of one or more host processors 1805 and / or within the accelerator integrated circuit 1836.
[0364] One embodiment allows GPU memory 1820 to be mapped as part of system memory and accessed using shared virtual memory (SVM) technology without suffering the performance drawbacks associated with full system cache coherence. In at least one embodiment, the ability to access GPU memory 1820 as system memory without the heavy overhead of cache coherence provides a favorable operating environment for GPU offloading. In at least one embodiment, this arrangement allows the host processor 1805 to software-set operands and access computation results without the overhead of conventional I / ODMA data copying. In at least one embodiment, such conventional copying includes driver calls, interrupts, and memory-mapped I / O (MMIO) accesses, all of which are less efficient than simple memory accesses. In at least one embodiment, the ability to access GPU memory 1820 without cache coherence overhead can be critical to the execution time of offloaded computations. In at least one embodiment, for example, in cases with high streaming write memory traffic, cache coherence overhead can significantly reduce the effective write bandwidth seen by GPU 1810. In at least one embodiment, the efficiency of operand setting, the efficiency of result access, and the efficiency of GPU computation can play a role in determining the effectiveness of GPU offloading.
[0365] In at least one embodiment, the selection of GPU bias and host processor bias is driven by a bias tracker data structure. In at least one embodiment, for example, a bias table can be used, which may be a page-granular structure (e.g., controlled at the memory page level) comprising one or two bits of memory pages attached to each GPU. In at least one embodiment, with or without a bias cache (e.g., for caching frequently / recently used entries in the bias table) in GPU 1810, the bias table can be implemented across one or more stolen memory ranges of GPU memory 1820. Alternatively, in at least one embodiment, the entire bias table can be maintained within the GPU.
[0366] In at least one embodiment, prior to actual access to GPU memory, an access to the bias table entry associated with each access to GPU-attached memory 1820 is performed, resulting in the following operations: In at least one embodiment, a local request from GPU 1810 to find its page in the GPU bias is forwarded directly to the corresponding GPU memory 1820. In at least one embodiment, a local request from the GPU to find its page in the host bias is forwarded to processor 1805 (e.g., via the high-speed link described herein). In at least one embodiment, a request from processor 1805 to find the requested page in the host processor bias completes a request similar to a normal memory read. Alternatively, a request for a page pointing to the GPU bias can be forwarded to GPU 1810. In at least one embodiment, if the GPU is not currently using the page, the GPU may subsequently migrate the page to the host processor bias. In at least one embodiment, the page bias state can be changed through a software-based mechanism, a hardware-assisted software mechanism, or, in limited cases, a purely hardware-based mechanism.
[0367] In at least one embodiment, a mechanism for changing the bias state employs an API call (e.g., OpenCL), which subsequently invokes the GPU's device driver. The device driver then sends a message (or enqueues a command descriptor) to the GPU, instructing the GPU to change the bias state and, in some migration, performs a cache refresh operation on the host. In at least one embodiment, the cache refresh operation is used for migration from the host processor 1805 bias to the GPU bias, but not for the reverse migration.
[0368] In at least one embodiment, cache coherence is maintained by temporarily rendering GPU bias pages that the host processor 1805 cannot cache. In at least one embodiment, to access these pages, the processor 1805 may request access from the GPU 1810, which may or may not immediately grant access. Therefore, in at least one embodiment, to reduce communication between the processor 1805 and the GPU 1810, it is beneficial to ensure that the GPU bias pages are pages needed by the GPU, not those needed by the host processor 1805, and vice versa.
