Embodiment 1
[0058] figure 1 It is a schematic flowchart of the method for detecting the distance to the preceding vehicle in Embodiment 1 of the present invention. see figure 1 , the present embodiment provides a method for detecting the distance to the preceding vehicle, comprising:
[0059] Collect the RGB image and depth image of the front view of the vehicle; identify all the vehicles based on the RGB image, and extract the corresponding width and height data of each vehicle in the image; establish a coordinate system, and extract the horizontal and vertical coordinates corresponding to the upper left corner of each vehicle in the RGB image , match it with the width and height data of the corresponding vehicle and draw the bounding box of each vehicle; preset a target area box in the RGB image, and select a fixed point in the target area box as the target point; based on the bounding box of each vehicle The area and the area of the target area frame correspond to the calculation o...
Embodiment 2
[0092] see figure 1 with figure 2 , the present embodiment provides a vehicle-ahead distance detection system, comprising:
[0093] The image acquisition unit 1 is used to acquire the RGB image and the depth image of the front view of the vehicle;
[0094] The image recognition unit 2 is used to recognize all the vehicles based on the RGB image, and extract the corresponding width and height data of each vehicle;
[0095] Constraint frame generating unit 3 is used to establish a coordinate system, extract the horizontal and vertical coordinates corresponding to the upper left corner of each vehicle in the RGB image, match it with the width and height data of the corresponding vehicle, and draw the constraint frame of each vehicle;
[0096] The target area selection unit 4 is used to preset a target area frame in the RGB image, and select a fixed point in the target area frame as the target point;
[0097] The feature calculation unit 5 is used for correspondingly calculati...
