Problems solved by technology
However, the inventor found that in the traditional technology, the storage of bounding box information takes up many threads, resulting in a small number of bounding boxes for one thread operation, which makes the determination of the bounding box less efficient

The invention relates to a method and device for determining a bounding box, computer equipment and a storage medium. The method comprises the following steps: acquiring a bitmap in a thread containedin a thread group, wherein the bitmap of any thread corresponds to at least one independent initial bounding box, and the initial bounding box is a detection box obtained by performing image target detection on the target object; running the threads in the thread group in parallel to enable the bitmaps in the first remaining threads and the bitmaps in the first target threads to be subjected to first bit AND operation, wherein the first target thread is selected from the thread group, and the first remaining thread is a thread, except the first target thread, in the thread group; obtaining overlapping information between the initial bounding boxes corresponding to the threads of the thread group according to a result of the first bit AND operation; and determining an independent boundingbox from the initial bounding boxes corresponding to the threads of the thread group according to the overlapping information, and taking the independent bounding box as a target bounding box of the target object. The whole bounding box determination process can be quickly completed.
Description
technical field [0001] The present application relates to the technical field of bounding box determination, and in particular to a bounding box determination method, device, computer equipment and storage medium. Background technique [0002] Non-maximum suppression is widely used in artificial intelligence object detection post-processing. The neural network computes bounding boxes for a large number of objects and a score for each bounding box. Using the non-maximum suppression method (Non MaxImumsuppression, NMS) can remove most of the repeated bounding boxes and select the point with the highest score as the most suitable bounding box for the detected object, so as to achieve the purpose of detecting the object type, position and size. The non-maximum suppression algorithm itself can consider parallel computing to increase the speed, so how to achieve the best combination of efficiency and energy consumption under the parallel algorithm, that is, use less GPU (Graphics...
