Problems solved by technology

When the omnidirectional visual system composed of hyperbolic mirrors is located in the center of the site, it can be clearly seen from the obtained panoramic images of the site that the straight lines of the site boundary are imaged as arcs; This barrel distortion is difficult to correct. As far as the application of visual navigation of mobile robots is concerned, the consequence of this distortion is that it is difficult to accurately estimate the position of the target point on the field through the panoramic image, and it brings great problems to the self-localization of the robot. error

Abstract

The invention discloses an all direction sighting device that includes all direction reflector and camera. All direction reflecting lens and camera are installed in the tunnel body. The center pointer of the al direction reflecting lens is located on the optic axis of the camera, and the camera installation base is set on leveling regulation mechanism. The all direction reflection lens is made up of level geometric proportion lens and vertical geometric proportion lens. The invention could realize the distance relation of panorama and real scene linear.

Description

technical field [0001] The present invention mainly relates to the field of computer vision devices, in particular to an omnidirectional vision device for collecting panoramic images, which can also be applied to mobile robot visual navigation, robot football games, monitoring and monitoring, video conferencing, scene recovery and other technologies field. Background technique [0002] In the prior art, an omnidirectional vision system is composed of an omnidirectional mirror and a camera. The omnidirectional mirror plays the role of reflecting light, and the camera collects the light reflected by the omnidirectional mirror through lens refraction to obtain a panoramic image. For the imaging effect, it also depends on factors such as the positional relationship between the omnidirectional reflector and the camera and whether they are horizontal. In different environments and states, the omnidirectional reflector and the camera must be adjusted in several directions. Precise...
