Abstract

The invention provides a calibration device and calibration method for a compound-eye type spherical vision system. The calibration device comprises a data acquisition system and an angle adjustment device. The angle adjustment device consists of a sensor assembly and a mechanical adjustment mechanism. The sensor assembly includes an angle sensor A, a linear displacement sensor B and an angle sensor C, wherein the sensors are connected with an input terminal of a multi-channel data acquisition card of the data acquisition system by leads; the angle sensor A collects a rotation angle theta2 of a rocker arm around an Y axis; the linear displacement sensor B collects a distance d between a light source and a spherical vision system; and the angle sensor C collects a rotation angle theta 1 of the spherical vision system around a Z axis. Compared with the traditional calibration method, the provided calibration method has the following advantages: one-time integrated mounting and calibration of the large-range spherical surface can be realized. While the precision requirement is met, the cost is reduced, the efficiency is improved, and the operation becomes simple and convenient.

Description

technical field [0001] The invention belongs to the field of optical detection, and particularly relates to a calibration device and a calibration method for a compound-eye spherical vision system. Background technique [0002] With the development of bionics, biological compound eyes have received more and more attention in the application field in recent years. The compound eye has the structural characteristics of multi-channel simultaneous imaging and sub-eye surface distribution, as well as high centralized processing capability of neural network, which can quickly complete tasks such as high-precision detection, positioning, and measurement of moving objects. Using this part of the characteristics of biological compound eyes, scholars at home and abroad have developed various compound eye imaging systems and various similar visual imaging systems. Different from the biological compound eye system, the artificial compound eye vision system is assembled from various sca...
