Device for single camera to achieve spatial 360 degree annular panoramic and local precise imaging

Abstract

The invention discloses a device for a single camera to achieve spatial 360 degree annular panoramic and local precise imaging and solves the technical problems that the single camera can achieve spatial 360 degree rough observation imaging and local precise imaging at the same time. The technical scheme is as follows: an optical lens is perpendicularly arranged on a support base after connected with a CCD (charge coupled device) camera; a system computer is connected with the optical lens and the CCD camera; a spatial 360 degree panoramic imaging part comprises a hyperboloid-shaped reflector provided with a center hole, and the hyperboloid-shaped reflector is coaxially arranged above the optical lens through an annular ling transmitting support cylinder; and a local imaging part comprises a flat mirror, a mirror angle adjustment bracket and a mirror horizontal rotary table, the flat mirror is located above the hyperboloid-shaped reflector and arranged on the mirror horizontal rotary table through the mirror angle adjustment bracket, and the flat mirror corresponds to the center hole of the hyperboloid-shaped reflector. The device has the benefits as follows: the device cost is reduced, power consumption and fault rates are reduced, the maintenance and the usage are facilitated, and the application range is expanded.

Description

technical field [0001] The invention relates to an imaging device, in particular to a device for realizing 360-degree circular panorama and local accurate imaging with a single camera. Background technique [0002] A single camera can only perform visual observation or imaging in a certain direction, which cannot meet the multi-directional simultaneous monitoring tasks in the field of video surveillance. The emergence of multi-camera image stitching technology meets the needs of multi-directional monitoring, but the selection and information fusion between multiple cameras in dynamic target tracking is a difficult point. The pan / tilt is a camera installation platform that can provide multi-angle observation. Through the pan / tilt, a camera can also be rotated 360 degrees to monitor the entire scene, but its rotation speed is limited and the ability to collect the entire panoramic field of view is limited, so it is impossible to observe multiple directions at the same time.

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, It is a reliable means of collecting panoramic visual information. However, when the panoramic image increases the field of view, it also leads to a decrease in the ability to distinguish the details of the scene, and the observation target is prone to distortion. Therefore, a large-scale scene imaging monitoring is designed. The accurate and distortion-free imaging observation device for scene details has high use value
