Problems solved by technology

[0003] To mark the low-point camera on the high-point camera screen, you can use the method of manual labeling. Although it can be very accurate and reliable, the labeling process will be very complicated, with a huge workload and low efficiency.
During the construction of the monitoring system, the ground coordinates of the low-point cameras will be manually entered into the database system, but there is currently no way to automatically convert the ground coordinates of the low-point cameras into the screen coordinates of the high-point cameras

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 It shows a schematic diagram of the conversion method of ground coordinates and wide-angle camera screen coordinates of the present invention, and shows the specific implementation process of the method, including:

[0038] In step 101, the ground coordinates of the target location are obtained;

[0039] The target location here is the current object of interest, and in a possible target tracking scenario, it can be a patrol convoy or a police car deployed in a security zone. In a possible implementation, these target objects that need to be tracked will actively report their own ground coordinates. Optionally, it is the ground coordinates of the target objects. In the present invention, other feasible ground methods tha...

Abstract

The invention discloses a Method, system and device for converting ground coordinates and wide-angle camera image coordinates, and relates to the field of security and protection. The method comprisesthe steps that ground coordinates of a target position are acquired; And converting the ground coordinates of the target position into wide-angle camera image coordinates according to a coordinate conversion mechanism. According to the technical scheme, by establishing the coordinate conversion mechanism between the ground coordinates of the target and the image coordinates of the wide-angle camera, mutual conversion between the ground coordinates of the target and the image coordinates of the wide-angle camera can be conveniently achieved, and the method is simple and has good accuracy and reliability.

Description

technical field [0001] The invention relates to the security field, in particular to a conversion method, system and device for ground coordinates and wide-angle camera screen coordinates. Background technique [0002] In the field of security, marking on the trigger screen is a very popular application method: directly marking monitoring equipment, buildings and roads on the trigger screen is very intuitive to operate. Specifically, in a bolt-action screen with a very high installation height, such as an installation height of about 100 meters, we call it a high-point camera, and all ground cameras, such as an installation height of about 6 meters, are called low-point cameras, and mark them on the high In the screen of the point camera, when operating the low point camera, you can directly click the marked icon representing the low point camera in the video screen of the high point camera to open the video of the low point camera, no longer need to go through the device tr...
