Document Type and Number:
WIPO Patent Application WO/2022/000862
Kind Code:
A1
Abstract:
A method and apparatus for detecting an object in a fisheye image, and a storage medium, which belong to the technical field of image processing. The method comprises: acquiring a fisheye image, wherein the fisheye image comprises a plurality of object regions at different angles in a plane, and the angle of the object region refers to an angle of an object in the object region with respect to the circle center of the fisheye image; performing image cropping on the fisheye image on the basis of the circle center of the fisheye image and according to a plurality of cropping angles, so as to obtain cropped images, wherein the cropping angles comprise angles corresponding to the plurality of object regions; splicing the cropped images to obtain a spliced image; performing object detection on the spliced image by using an object detection model, so as to obtain an object detection box; and mapping the object detection box back to the fisheye image according to the corresponding cropping angle, so as to obtain an object detection result. The problem whereby an existing object detection model cannot perform detection on a fisheye image can be solved, and the detection of an object position and an object angle in a fisheye image can thus be realized.
