Front-view video processing method and system for vehicle and corresponding vehicle

The invention provides a front-view video processing method for a vehicle. The method comprises the following steps: acquiring a video in front of the vehicle; pre-processing the acquired video, wherein the pre-processing comprises correction and perspective transformation of an image of the video; carrying out target identification on the preprocessed video to obtain a priori frame, and taking the priori frame as a single-frame two-dimensional detection frame of the target; and performing one or more of the following items: for the single-frame two-dimensional detection frame, extracting a region of interest to obtain the region of interest; and performing single-frame three-dimensional target detection on the preprocessed video based on the single-frame two-dimensional detection frame to obtain a single-frame three-dimensional detection frame, and performing target tracking processing on the single-frame two-dimensional detection frame based on comparison of continuous multiple frames of the preprocessed vi
