Multi-target monitoring method and system based on panoramic camera and galvanometer camera

Abstract

The invention belongs to the technical field of security monitoring, and specifically relates to a multi-target monitoring method and system based on a panoramic camera and a galvanometer camera, aiming to solve the problem that the existing imaging technology cannot capture all targets in a short period of time in long-distance area observation. target audience issues. The invention includes: coordinate calibration and parameter calibration of the panoramic camera, vibrating mirror unit and high-speed camera, real-time recording of the detection area through the panoramic camera using a streaming mode, and obtaining the center position and target position of the panoramic image target through feature extraction and classifier category, calculate the galvanometer control voltage based on the central position of the panoramic image target, make the high-speed camera traverse all the central positions of the panoramic image target, combine the panoramic image data with the high-speed camera image, and obtain multi-channel multi-target high-definition monitoring images. The present invention realizes simultaneous monitoring of multiple targets, display of multiple virtual cameras, real-time long-distance area observation and high-definition shooting of multiple targets.

Description

technical field [0001] The invention belongs to the technical field of safety monitoring, and in particular relates to a multi-target monitoring method and system based on a panoramic camera and a vibrating mirror camera. Background technique [0002] In the process of shooting distant objects, the panoramic camera can obtain a wider field of view due to its shorter focal length, usually the viewing angle range is above 60 degrees, and even a 360-degree panorama can be achieved. Fixing the panoramic camera can obtain the overall image of the area to be observed, but the details of the object of interest in the area to be observed cannot be obtained. [0003] Telephoto cameras are clearer and retain more details when shooting distant objects, but have a narrower field of view, usually within 15 degrees, and can only observe small-scale scenes. The scanning galvanometer is a high-precision, high-speed servo control system composed of a drive control board and a high-speed ser...
