Multi-scale image target detection method and system, electronic equipment and storage medium

The invention provides a multi-scale image target detection method and system, an electronic device and a storage medium, a detection model is trained based on a small-scale image, the recognition of an object target frame in the small-scale image is carried out through the detection model, the object target frame is mapped into a large-scale image based on the object target frame recognized from the small-scale image, the target frame of the same object is found in the large-scale image, and finally, the detection model is optimized by using the images with different scales, so that the data volume of a detection model training set is increased, the scales of the images in the training set are expanded, and the optimized detection model is suitable for identifying object targets in various images with different scales, and the target detection precision is improved. 本发明提供一种多尺度影像目标检测方法、系统、电子设备及存储介质，基于小尺度影像训练一个检测模型，利用该检测模型对小尺度影像中的物体目标框进行识别，基于从小尺度影像中识别出的物体目标框，将其映射到大尺度影像中，在大尺度影像中找到同一个物体的目标框，最后利用不同尺度影像对检测模型进行优化，这
