In a model processing method, a first local server which is disposed between a cloud server and an edge device obtains a data set of the edge device. The data set comprises data used when the edge device performs computing by using a first model provided by the cloud server. The first local server determines, based on the data set of the edge device, a first gradient value for updating the first model, and sends the first gradient value to the cloud server for use by the cloud server to update the first model.

A positioning method includes obtaining an estimated extrinsic parameter of a camera and an intrinsic parameter of the camera, where the estimated extrinsic parameter of the camera is obtained based on world coordinates of a plurality of estimation points in a shooting region of the camera, image coordinates of the plurality of estimation points, and the intrinsic parameter of the camera; obtaining image coordinates of a target in an image shot by the camera; and obtaining world coordinates of the target based on the estimated extrinsic parameter of the camera, the intrinsic parameter of the camera, and the image coordinates of the target.
