Problems solved by technology

[0004] (1) Using the Mask R-CNN model to perform faster and better detection operations requires a hardware platform equipped with high-performance CPU and GPU, which is often not available to ordinary application personnel;
[0005] (2) The size and file size of the remote sensing image far exceeds the image usually detected by the Mask R-CNN model, so the common method now is to crop the remote sensing image into a small image that meets the requirements, and then give it to the Mask R-CNN model separately. Detection, which increases a lot of additional data preprocessing workload;
[0006] (3) The detection result of the Mask R-CNN model is a pixel image without geographic coordinates and has no geographic spatial meaning. It needs to be manually converted into geographic data such as space vectors to have practical application value;
[0007] (4) The ground object detection of the Mask R-CNN model is difficult to integrate with other related geographic processing operations to form a unified remote sensing image ground object detection process
