Apparatus for rapidly correcting installation position of panoramic vision measuring system

Abstract

The invention provides an apparatus for rapidly correcting an installation position of a panoramic vision measuring system. The apparatus comprises a viewing module, a perspective imaging module and a protection module, wherein the viewing module comprises a hyperboloid reflector installed in a protective glass tube and a hyperboloid reflector connector arranged on the top of the protective glass tube; the perspective imaging module comprises a scientific grade camera with a high frame frequency, and a perspective lens; and the protective module comprises a protective glass tube. The viewing module is connected with the protection module through a connector; the perspective imaging module is installed in the protection module by a support; and the top of the hyperboloid reflector is a circular plane whose center is the original summit of the hyperboloid reflector, wherein the circular plane is in parallel with the bottom of the hyperboloid reflector. The apparatus provided by the invention has a simple structure and a good adaptability and needs no external auxiliary measures; the apparatus can realize high-precision correction of the installation position of the panoramic vision measuring system, therefore possessing a high practical value.

Description

technical field [0001] The invention relates to a test device, in particular to a device for correcting the installation position of a panoramic vision measurement system. Background technique [0002] Catadioptric panoramic vision can be traced back to 1970, when Dr. ReeS of the United States proposed for the first time in his patent the use of a hyperboloid mirror to achieve panoramic imaging. The advantage of the hyperboloid panoramic vision system is that it has a single projection center, and the vertical viewing angle can reach (-90°-45°). The panoramic image can be transformed into an ordinary perspective image and a cylindrical image; the perspective lens is the most commonly used one. Imaging lenses are mature in technology, diverse in variety, and flexible in selection, and if the curvature of the selected mirror is small, astigmatism can be reduced. The emergence of the panoramic vision system has promoted the development of a series of related theoretical resear...

Problems solved by technology

The above calibration methods are all based on the premise of the central catadioptric system or the assumption that the system satisfies the single-view constraint model. If the relationship between the mirror and the camera in the system does not satisfy the assumption, it will inevitably lead to calibration errors.
