Embodiment 1

[0074] The invention provides a method for target distance detection, such as figure 1 shown, including:

[0075] Step 101, acquiring a target image through a camera;

[0076] The applicable scenarios of the embodiments of the present invention include but are not limited to automatic driving scenarios. In the automatic driving scenario, the camera device is a camera device on an automatic driving vehicle. When the vehicle is started, the camera device starts to shoot driving videos, so The target image mentioned above is a certain frame picture in the driving video.

[0077] The target may be, but not limited to, a person, a vehicle, an animal, a building, and the like.

[0078] When the target image of the item is acquired in the above step 101, if the acquired images are from multiple angles of the target, it is possible, but not limited to, to select an image with the best pixels / including the specified part of the target as the target image. There are too many limitati...

Embodiment 2

[0141] This embodiment is a device for target distance detection, such as figure 2 Said, comprises processor 201 and memory 202, wherein, said memory, 22 stores executable program code, when said program code is executed, makes described processor 201 be used for performing the following steps:

[0142] Obtain the target image through the camera device;

[0143] Detecting the target in the target image, extracting the two-dimensional feature information of the target, the two-dimensional feature information of the target includes the physical size of the target and the position area of ​​the target in the target image;

[0144] According to the physical size of the target and the position area of ​​the target in the target image, the distance of the target relative to the camera device is determined through a distance search algorithm.

[0145] Optionally, the two-dimensional characteristic information of the target further includes a deviation angle of the target, and the d...

Embodiment 3

[0162] This embodiment provides a device for target distance detection, the schematic diagram of the device is as follows image 3 As shown, the above-mentioned devices include:

[0163] an acquisition unit 301, configured to acquire a target image through a camera;

[0164] The extraction unit 302 is configured to detect the target in the target image, and extract the two-dimensional feature information of the target, the two-dimensional feature information of the target includes the physical size of the target and the position area of ​​the target in the target image ;

[0165] The determining unit 303 is configured to determine the distance of the target relative to the camera device through a distance search algorithm according to the physical size of the target and the position area of ​​the target in the target image.

[0166] Optionally, the two-dimensional characteristic information of the target further includes a deviation angle of the target, and the deviation ang...

Abstract

The invention discloses a method and device for target position detection, which solves the problem that the existing target detection algorithm cannot output the distance between the target and the camera device. The method includes: acquiring a target image through the camera device; Perform detection and extract the two-dimensional feature information of the target, the two-dimensional feature information of the target includes the physical size of the target and the position area of ​​the target in the target image; according to the physical size of the target and the position of the target in the target In the position area in the image, the distance of the target relative to the camera device is determined through a distance search algorithm. The invention detects the target in the target image, extracts the two-dimensional characteristic information of the target, and combines the distance search algorithm to obtain the relatively accurate distance information of the target distance camera device.

Description

technical field [0001] The invention relates to the technical field of target detection, in particular to a method and device for target position detection. Background technique [0002] Cameras are very common in daily life, and are generally used to complete basic functions such as taking pictures and video recordings. However, with the advent of autonomous driving and artificial intelligence, it is possible to obtain more intelligent result requirements through the camera, that is, through the field of view of the camera, analyze and perceive changes in the environment and make judgments, and feed back the results to the terminal or cloud processor. Serving richer applications. [0003] Target detection (also known as target extraction) is a basic application of machine vision. It is an image segmentation based on target geometric and statistical features, which combines target segmentation and recognition into one. [0004] Compared with image recognition, object detec...
