Embodiment Construction
[0047] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0048] Such as figure 1 As shown, a road vehicle shadow feature extraction method, the specific steps are as follows:
[0049] Step 1: Extraction and preprocessing of video data:
[0050] 1-1. Read the video data of the vehicle in front from the camera, and perform geometric constraints on each frame of image in the video data.
[0051] Suppose the width and height of the original image A in the video data are Aw and Ah respectively, and the original image A is intercepted through geometric constraints to obtain the intercepted image B; the width of the image B is [Aw / 4,3×Aw / 4], the height of B is [Ah / 2-Ah / 10, Ah-Ah / 10].
[0052] 1-2. Extract the V component in the HSV channel as a single-channel image VImg.
[0053] 1-3. Extract the binarized edge map SImg of the single-channel image VImg.
[0054] Step 2: Shadow Threshold C...
