Dynamic monitoring camera device and dynamic monitoring method

Abstract

The invention provides a dynamic monitoring camera device and a dynamic monitoring method, and relates to the technical field of monitoring. The dynamic monitoring camera device comprises a spectroscope surface, a wide-angle camera, a light path adjusting module, a telephoto camera, a pupil transmission module and a light path controller, wherein a reflected light path after light splitting is received through the wide-angle camera during actual monitoring, a wide-angle image containing a monitoring target is obtained; a transmission light path is adjusted after light splitting according to aposition adjustment signal of the monitoring target in the wide-angle image, so that the transmission light path is transmitted to a telephoto camera, a telephoto image containing the monitoring target is obtained, and the detail monitoring of the target is achieved. The wide-angle camera acquires the wide-angle image in a large viewing angle range, and adjusts the angle of the transmission lightpath according to the position of the monitoring target in the wide-angle image, so that the telephoto camera can acquire the telephoto image containing the monitoring target without rotating the whole cradle head and the camera, the response speed is high, and high-dynamic real-time accurate monitoring of details of the high-speed moving target is realized.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a dynamic monitoring camera device and a dynamic monitoring method. Background technique [0002] In the prior art, in the moving target tracking system based on the pan-tilt, the camera is usually fixed on the pan-tilt, and the pose is adjusted in real time when capturing the dynamic target, so as to obtain an image focusing on the target and centering the target with an appropriate viewing angle. In order to observe the moving details of the target, a telephoto camera with a large depth of field and a small field of view is often selected. When tracking a high-speed random moving target, due to the highly nonlinear trajectory and the occlusion of the external environment, the target will leave the field of view of the telephoto camera during the tracking process, resulting in the loss of the target. [0003] However, due to the large mass of the mechanical rotating head and...

AI Technical Summary

Problems solved by technology

When tracking a high-speed random moving target, due to the highly nonlinear trajectory and the occlusion of the external environment, the target will leave the field of view of the telephoto camera during the tracking process, resulting in the loss of the target.

[0003] However, due to the large mass of the mechanical rotating head and the camera, the dynamic performance of the system is poor, and it is impossible to achieve stable tracking of high dynamic moving targets.

A small field of view will reduce the tolerance of the tracking system for moving targets

Therefore, it is difficult to realize the dynamic monitoring of the details of high-speed moving targets in the existing technology
