Document Type and Number:
Japanese Patent JP2018096727
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical axis adjusting device and optical axis adjusting method of line sensor camera for stereo measurement, capable of informing a deviation of an optical axis of each line sensor camera and its adjustment direction when performing stereo measurement by using the line sensor cameras.SOLUTION: The optical axis adjusting device of line sensor camera for stereo measurement is configured with: a cylindrical target 1 which is a columnar body rotatably supported and has, on its peripheral surface, a white region 1and a black region 1alternately colored in the axial direction and the circumferential direction; an image recording unit 21 for recording an image of the cylindrical target 1 rotating using a plurality of line sensor cameras 3A and 3B; an image processing unit 22 for determining necessity of adjusting the angle and position of each line sensor camera 3A, 3B and the adjustment direction based on the image; and an optical axis adjustment determination section 2 having an adjustment direction display section 23 for displaying the obtained adjustment directions of the line sensor cameras 3A, 3B.SELECTED DRAWING: Figure 1
