Title:
TARGET DETECTION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/077868
Kind Code:
A1
Abstract:
A target detection method and device. The method comprises: obtaining a plurality of bounding boxes on a target image and scores of the plurality of bounding boxes, the scores being used for representing the confidence that the bounding box comprises a target object (201); dividing the target image to obtain a plurality of grids, and determining the grids to which the plurality of bounding boxes belong (202); traversing the plurality of bounding boxes, calculating the overlapping degree between a reference bounding box and an adjacent bounding box, and obtaining a target bounding box according to the overlapping degree (203); and determining the target detection result according to the score of the target bounding box (204). According to the method, by performing grid division on a target image, determining grids to which bounding boxes belong, and determining the neighboring relation of the bounding boxes according to the neighboring relation between the grids, only the overlapping degree between the reference bounding box and the adjacent bounding box needs to be calculated when an NMS algorithm operation is performed, effectively reducing the time complexity of NMS and improving the target detection efficiency.
