Omni-directional visual monitoring system combining rough and fine modes

Abstract

The invention aims to provide an omni-directional visual monitoring system combining rough and fine modes. The omni-directional visual monitoring system comprises a panorama visual image acquisition subsystem, a general visual angle image acquisition subsystem and an embedded image acquisition processing and data transmission subsystem, wherein the panorama visual image acquisition subsystem comprises a double curved surface reflector, an imaging lens and a panorama camera; the imaging lens is arranged on the panorama camera; the double curved surface reflector is arranged above the imaging lens; the general visual angle image acquisition subsystem comprises a cloud deck which is provided with an industrial camera; the general visual angle image acquisition subsystem is fixedly arranged at the top of the panorama visual image acquisition subsystem; the embedded image acquisition processing and data transmission subsystem is respectively connected with the panorama visual image acquisition subsystem and the general visual angle image acquisition subsystem, is used for acquiring and outputting the image information of the panorama camera and the industrial camera, and sending a control command to the panorama camera and the industrial camera. With the adoption of the omni-directional visual monitoring system combining the rough and fine modes, not only can wide-angle view monitoring be carried out, but also the precision observation can be carried out on view detail.

Description

technical field [0001] The invention relates to a monitoring device. Background technique [0002] Due to the limitation of the monitoring range, a single camera obviously cannot meet the requirements for 360-degree monitoring of the entire scene, so the use of multiple cameras appears to expand the effective range of monitoring, but for the multi-camera tracking system, we need to determine the Which camera or which image to use at each moment, the selection and information fusion between multiple cameras is a difficult point. The PTZ is a kind of all-round monitoring equipment, relying on the 360-degree rotation of a camera to monitor the entire scene, but the monitoring angle of the camera is limited after all, there must be a monitoring dead angle at a certain moment, and its image algorithm is complex, which does not achieve the real meaning All-round monitoring on the machine, and there is equipment wear and tear during its operation, so the service life is short.

Problems solved by technology

The camera based on the omnidirectional visual sensor has very prominent advantages, its field of view is wide (360 degrees), and the information in a hemispheric field of view can be compressed into an image, and the amount of information in an image is larger, and any point in the panoramic image is Corresponds to a certain point in the monitoring space, so the spatial position calibration algorithm is simple, and there is no need to aim at the target during monitoring, which makes the algorithm for acquiring visual information, detecting and tracking moving objects within the monitoring range simpler, and is a fast, Reliable panoramic visual information collection method, but the panoramic image increases the field of view and also causes the image to reduce the ability to distinguish the details of the scene
