Embodiment Construction

[0046] At present, the monitoring equipment of gun-ball linkage is generally used in substations, which is to form a global picture of the monitored area through the gun camera with a wide field of view, and use the global picture of the gun camera as a reference to control the ball camera with a small field of view through linkage. Output local detail image. Through the gun-ball linkage, not only can the goal of seeing the whole picture be realized, but also for the system with people in the loop, it can also realize faster and more purposeful control of the high-speed ball; for the unattended system, the gun-ball linkage controller can intelligently analyze the gun It can automatically control the high-speed ball to track and monitor suspicious targets and areas according to the specific target and behavior situation of the machine image, so as to realize automatic intelligent surveillance. However, in practical applications, the gun-type monitoring device may fail to detect...

Abstract

The invention provides a target identification method, a target identification device, a gun-ball linkage monitoring method and a gun-ball linkage monitoring system. The method is based on longitude and latitude positioning information under a world coordinate system and a coordinate conversion relationship between a preset world coordinate system and a gun-shaped lens coordinate system of a gun-shaped monitoring device. The longitude and latitude coordinates are mapped to the lens coordinate system of the monitoring device, the position of the target to be monitored in the monitoring image isfurther obtained, and the technical problem that the monitoring effect is unstable due to the fact that a target is lost frequently under interference of light, shielding and other environmental factors in a traditional target positioning mode relying on image feature recognition is solved.

Description

technical field [0001] The present application relates to the technical field of monitoring, in particular to a target recognition method and device, and a gun-ball linkage monitoring method and system. Background technique [0002] The substation is an important part of the transmission network. The stable operation of the equipment in the substation is inseparable from the daily maintenance of the staff. However, because there are a large number of high-voltage equipment in the substation, there are many dangerous areas, and safety accidents are prone to occur. In order to ensure the safety of the staff, a large number of monitoring devices are usually installed in the substation at present, so that the employees in distress can be rescued in time through tracking and monitoring. [0003] At present, the monitoring in the substation generally adopts the monitoring equipment linked by the gun and the ball. However, in practical applications, the target is often lost, which ...
