Abstract

The invention discloses equipment for calibration of camera intrinsic parameters. The equipment comprises a bearing assembly, an angle adjusting assembly, a carrying assembly and a graph card assembly, wherein the bearing assembly is arranged at an adjusting end of the angle adjusting assembly; the angle adjusting assembly is arranged at a carrying end of the carrying assembly; the graph card assembly is provided with a graph card piece arranged on a carrying path of the carrying assembly; the bearing assembly is used for bearing a camera; the carrying assembly drives the angle adjusting assembly to move; the angle adjusting assembly drives the bearing assembly to move; and the angle adjusting assembly adjusts a placing angle of the bearing assembly in an XY plane, so that the camera borne by the bearing assembly corresponds to the graph card piece. According to the invention, through cooperation of the angle adjusting assembly and the carrying assembly, adjustment of relative positions and angles between the camera borne in the bearing assembly and the graph card piece is rapidly achieved, so that the efficiency of the calibration of the camera intrinsic parameters is improved.

Description

technical field [0001] The present invention relates to the technical field of camera internal reference calibration, in particular, mainly relates to camera internal reference calibration equipment. Background technique [0002] The internal parameter calibration of the camera is simply a process of changing from the world coordinate system to the image coordinate system. position and angle relationship. At present, there are already semi-automated equipment to achieve camera internal parameter calibration, but manual participation is still required when adjusting the relative position and angle between the camera and the test chart, and the efficiency of the overall camera internal parameter calibration is low. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a device for calibrating internal parameters of a camera. [0004] A camera internal parameter calibration device disclosed in the present invention in...
