Abstract
This application discloses a site model updating method and system in the field of artificial intelligence. The method includes: obtaining a surveillance image; determining, based on the obtained surveillance image, a change type of a device that changes and a change amount corresponding to the change type; calculating a pose and camera parameter of the surveillance image based on the surveillance image and a site model; determining, based on the pose and camera parameter of the surveillance image, a pose of the device that changes; and updating the site model based on the pose of the device that changes, the change type, and the change amount corresponding to the change type.
Claims20
A site model updating method, the method comprising:
- obtaining a surveillance image and determining, based on the surveillance image, a change type of a device that changes in the surveillance image and a change amount corresponding to the change type;
- calculating a pose of the device and a camera parameter of the device for the surveillance image based on the surveillance image and a site model;
- determining, based on the pose of the device and the camera parameter of the device for the surveillance image, a pose of the device that changes in the surveillance image;
- and
- updating the site model based on the pose of the device that changes in the surveillance image, the change type, and the change amount corresponding to the change type.
An apparatus, comprising:
- an interface;
- a memory storing instructions;
- and
- at least one processor in communication with the interface and the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
- obtain a surveillance image and determine, based on the surveillance image, a change type of a device that changes in the surveillance image and a change amount corresponding to the change type;
- calculate a pose of the device and a camera parameter of the device for the surveillance image based on the surveillance image and a site model;
- determine, based on the pose of the device and the camera parameter of the device for the surveillance image, a pose of the device that changes in the surveillance image;
- and
- update the site model based on the pose of the device that changes in the surveillance image, the change type, and the change amount corresponding to the change type.
A site model updating system, the system comprising:
- a device change detection apparatus configured to determine a change type of a device that changes in the surveillance image and a change amount corresponding to the change type, based on a surveillance image;
- and
- a processor configured to:
- obtain the surveillance image;
- calculate a pose of the device and a camera parameter of the device for the surveillance image based on the surveillance image and a site model;
- determine, based on the pose of the device and the camera parameter of the device for the surveillance image, a pose of the device that changes in the surveillance image;
- and
- update the site model based on the pose of the device that changes in the surveillance image, the change type, and the change amount corresponding to the change type.
