Embodiment
[0103] This example discloses an image stitching method for offshore aquaculture areas based on non-uniform precision. It mainly combines the pose and feature points to stitch the image first within the sub-area and then between the sub-areas, as shown in figure 1 As shown, the specific process is as follows:
[0104] S1. Use drones to take low-altitude aerial photography of the breeding area to obtain aerial images, perform preprocessing operations on the aerial images, adjust the brightness of the aerial images and obtain the mask of the cage area;
[0105] For image preprocessing, this includes aerial image dodging and cage mask acquisition. Due to the inconsistent exposure of the camera when taking pictures, the brightness of the finally acquired aerial images is inconsistent. The brightness of the aerial image will not only affect the look and feel of the final stitching result, but also adversely affect the grid optimization based on photometric alignment. Therefore, i...
