Embodiment Construction

[0045] Please refer to FIG. 2 , which is a schematic diagram of a preferred embodiment of the camera array calibration system according to the present invention. The camera array calibration system includes an image display 103, a camera array 101, a calibration plate 201, a clamping mechanism 104 that can adjust multiple degrees of freedom, and a controller 105 connected to the clamping mechanism 104, so users can use manual or It is the controller 105 that controls the operation of the clamping mechanism 104 . When the traditional camera array 101 is calibrated, it is necessary to move the object to be photographed or the camera array 101 for image scanning; the present invention uses a calibration plate 201 dedicated to the camera array 101, as shown in FIG. 4 , the calibration plate 201 includes a boundary pattern 211 , the vertical angle correction diagram 212, the horizontal angle correction diagram 213, the alignment pattern 215 and the light and dark stripes 216; in th...

Abstract

The present invention provides one kind of cameran array correcting system and process with simple configuration matching correcting board to shorten the correction time. The cameran array correcting system includes one cameran array; one holding mechanism capable of regulating the multiple freedom axes of the cameran array; one correcting board with pattern for static correction of the freedoms; and one controller capable of driving the holding mechanism to calibrate the position of the cameran array relative to the correcting board based on the scanning result to the pattern. The cameran array correcting process includes the steps of: providing one correcting board with the special correcting pattern; regulating the horizontal axis and the vertical axis of the holding mechanism to align the cameran array to the pattern; and regulating the vertical axis, the horizontal axis, the height axis and elevation axis with the pattern.

Description

technical field [0001] The present invention relates to a camera array calibration system and method, in particular to a simple imaging device and program designed using a special calibration plate and its proprietary calibration pattern, so that the camera can be adjusted without dynamic scanning Camera array calibration system and method for shortening calibration time. Background technique [0002] As shown in Figure 1, the calibration architecture of the known technology system includes a camera array 101, a standard calibration plate 203, a clamping mechanism 104, a platform (not shown) that can cause the standard calibration plate 203 to move relative to each other and control the movement Motion controller 102 of the platform. When calibrating the camera array, the calibration plate must be moved so that the camera array scans the calibration pattern on the standard calibration plate 203 within the imaging range 202 of the camera to obtain a one-dimensional image, wh...
