Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of intelligent driving, and particularly to a method, system, device, medium and vehicle for detecting the stationary state of a road sampling vehicle. Background Art
[0002] With the continuous development of technologies such as autonomous driving and intelligent transportation, more and more vehicles are equipped with an Advanced Driver Assistance System (ADAS). The fundamental of intelligent driving lies in safety. How to ensure the safety of a vehicle during driving is still the research focus of intelligent driving technology. In an intelligent driving assistance system, when the vehicle is in a stationary state, the collected data will contain duplicate data or data with high similarity. Since sending duplicate or highly similar data (such as image information) into a neural network model for training will occupy network training resources and cause interference to the training of the neural network model, affecting the training effect of the model. Therefore, removing duplicate or highly similar data during the data screening process, that is, sending appropriate and cleaned data into the neural network model before training can effectively improve the detection ability of the model and reduce the probability of the model having an overfitting problem.
[0003] To reduce data duplication, data screening or processing will be performed. During the data screening process, if the pictures collected when the road sampling vehicle is stationary need to be removed, it is necessary to judge whether the road sampling vehicle is in a stationary or moving state, and then screen out the road sampling data collected by the road sampling vehicle in the stationary state. In the prior art, to judge whether a road sampling vehicle is in a stationary state, usually the obtained video data is frame-processed, and the images at adjacent moments in the video sequence are differentially processed to identify moving vehicles. That is, the frame difference method is used to calculate the difference between two adjacent frames of images, and the moving area in the image is extracted through thresholding processing, and then it is judged whether the current road sampling vehicle is in a stationary state. Since there are differences between adjacent frames of images, it is impossible to accurately determine the threshold, and the accuracy of the detection result of the stationary state of the road sampling vehicle is low, so that during data screening, the data cannot be effectively de-duplicated. In addition, an ultrasonic sensor device is added to the vehicle to detect whether the road sampling vehicle is in a stationary state. The accuracy of the detection result is related to the selected ultrasonic sensor device. For an ultrasonic sensor with high precision, the detection accuracy is good, but the cost of system implementation is high. Summary of the Invention

[0016] Further, specifically, in the step S33, judging whether the road-sampling vehicle is in a stationary state specifically includes the following steps: calculate the difference between the height and width of the detection boxes of the same said static target in the t-th frame of image and the (t + 1)-th frame of image;
[0017] If the result of the difference is within the threshold range, judge that the road-sampling vehicle is in a stationary state;
[0018] On the contrary, if the result of the difference is not within the threshold range, judge that the road-sampling vehicle is in a moving state.
[0019] Further, specifically, in the step S3, it further includes: S34, obtaining all the same static targets and the detection frames associated with the static targets in the t-th frame image and the (t + 1)-th frame image, calculating the difference between the frame height and the frame width of the detection frames of all the same static targets, comparing the result of the difference with the threshold, and then using a voting mechanism to determine whether the road sampling vehicle is in a stationary state.

[0044] Embodiment 1
[0045] As Figure 1 shown, the embodiment of the present application provides a method for detecting the stationary state of a road collection vehicle, which specifically includes the following steps:
[0046] S1, obtaining images frame by frame from the video stream captured by an in-vehicle camera;
[0047] S2, using a CNN network model to identify at least one static target from the frame-by-frame images and extracting the detection box of each static target;
[0048] In step S2, the Kalman filtering algorithm is also used to optimize each detection box. The detection boxes extracted by the CNN network model will have a certain degree of dynamic changes. After the detection boxes are smoothed by the Kalman filtering algorithm, the processed detection boxes are more stable, which can further improve the accuracy of the detection results. It should be noted that the static targets are trees, traffic lights, or traffic signs, but are not limited thereto, and can also be other static objects on the traffic road. As Figure 2 shown, Figure 2 (a) are two adjacent frames of images in the stationary state, Figure 2(b) Images of two adjacent frames in the motion state. The dashed boxes in the figure represent static targets that can be used as references, and the solid boxes are the static targets detected by the CNN network model and the corresponding detection boxes.
[0049] S3. Use the Hungarian algorithm to match the detection boxes of two adjacent frames of images, obtain the detection boxes associated with the same static target in two adjacent frames of images, and determine whether the road sampling vehicle is in a stationary state according to the scale transformation relationship between the detection boxes associated with the same static target.
[0050] In this embodiment, step S3 specifically includes the following steps:
[0051] S31. Establish an image coordinate system;
[0052] S32. Set the detection box of the static target in the t-th frame of image as the reference box, represented by [x1, y1, x2, y2], and the detection box of the static target in the (t + 1)-th frame of image as the predicted reference box, represented by [x3, y3, x4, y4], as Figure 3 shown; calculate the intersection area A1 and the union area A2 between the reference box and the predicted reference box, and calculate the intersection over union (IOU) between two adjacent frames of images according to the intersection area and the union area. The calculation formula is: Furthermore, calculate the negative value of the intersection over union, -IOU.
[0053] As Figure 4 shown; when there are multiple static targets identified by the CNN network model, there will also be multiple corresponding detection boxes. Calculate the intersection over union between all detection boxes.
[0054] S33. Use the negative value of the intersection over union, -IOU, as the matching condition of the Hungarian algorithm to obtain the matching relationship between the t-th frame of image and the (t + 1)-th frame of image. Specifically, obtain the negative value of the intersection over union of the detection box of the t-th frame of image and the detection box of the (t + 1)-th frame of image, and form a matrix m represents the number of detection boxes in the t-th frame of image, n represents the number of detection boxes in the (t + 1)-th frame of image, Amn is the value of the negative value of the intersection over union, -IOU, between any detection box in the t-th frame of image and any detection box in the (t + 1)-th frame of image. Input the obtained matrix into the Hungarian algorithm for calculation, and extract the minimum value of all result sums based on the calculation result. This minimum value is the output value of the Hungarian algorithm, and the output value is the matching relationship between the t-th frame of image and the (t + 1)-th frame of image. Obtain the detection boxes associated with the same static target in the t-th frame of image and the (t + 1)-th frame of image according to the matching relationship, read and process the height and width of the detection boxes, and determine whether the road sampling vehicle is in a stationary state.
[0055] Further, determining whether the road sampling vehicle is in a stationary state specifically includes the following steps: calculating the difference between the height and width of the detection boxes of the same static target in the t-th frame image and the (t + 1)-th frame image; if the difference result is within the threshold range, it is determined that the road sampling vehicle is in a stationary state; conversely, if the difference result is not within the threshold range, it is determined that the road sampling vehicle is in a moving state. Specifically, as Figure 5 shown, the height of the detection box of the static target in the t-th frame image is H1 and the width is W1, the height of the detection box of the same static target in the (t + 1)-th frame image is H2 and the width is W2. Calculate the difference between the height H1 and the height H2, and the difference between the width W1 and the width W2. If the result is within the threshold range, it is determined that the height H2 = H1 and the width W2 = W1, and the road sampling vehicle is in a stationary state. To improve the accuracy of detection, the threshold range is between 0.01 and 0.05.
[0056] In this embodiment, step S3 further includes: S34, obtaining all the same static targets and the detection boxes associated with the static targets in the t-th frame image and the (t + 1)-th frame image, calculating the difference between the height and width of the detection boxes of all the same static targets, comparing the difference result with the threshold, and using a voting mechanism to determine whether the road sampling vehicle is in a stationary state, further improving the accuracy of the detection result.
[0057] The detection method for the stationary state of the road sampling vehicle of the present invention determines whether the road sampling vehicle is in a stationary state by comparing whether the size of the same static target in the image coordinate system changes between two adjacent frames of images. The accuracy of the detection result is high, the implementation cost is low, and it is easy to implement, facilitating subsequent effective data deduplication processing. In addition, voting on the size change of the same static target in two adjacent frames of images improves the robustness of the detection method and further improves the accuracy of the detection result.
