Target detection method and device based on fusion of multiple detection networks, and vehicle

The invention relates to the technical field of image data processing, and provides a target detection method and device based on multi-detection network fusion and a vehicle, and the method comprises the steps: correspondingly inputting a zoomed image and a cutout image of a current image into a zoomed target detection network and a cutout target detection network respectively, and obtaining a zoomed detection frame and a cutout detection frame respectively, correspondingly storing the data into a zooming and matting data set; any zoom and cutout detection frame is selected for matching; updating the scaled data set according to a matching traversal result to obtain an integrated data set; any detection frame is selected from the integrated data set of the current frame image and the previous frame image for matching to determine a detection target; and when the survival period of the detection target is greater than a set period, calculating the target credibility according to the semantic segmentation resu
