Abstract

The present invention discloses an included angle measurement method which comprises a step of obtaining the motion trajectory of a target point in a two-axis motion mechanism along the X-axis direction and the Y-axis direction of the two-axis motion mechanism, and a step of calculating the first angle and the second angle of the motion trajectory of the target point along the X-axis direction and the Y-axis direction and the x axis and y axis of the imaging plane coordinate system of a camera, wherein the first angle and the second angle are the angles of the camera and the x axis direction and y axis direction of the two-axis motion mechanism. The invention also provides an angle measurement device and an angle adjustment device. By using the embodiment of the present invention, the angle of the camera and the motion mechanism can be accurately measured, and the camera is adjusted based on the measured angle so as to ensure that the camera and the motion mechanism satisfy a certain positional relationship.

Description

technical field [0001] The invention relates to the field of industrial detection, in particular to an included angle measurement method and device, and an included angle adjustment method and device. Background technique [0002] In AOI (Automatic Optic Inspection, automatic optical inspection) detection equipment, it usually includes a camera and a motion mechanism. In general, mechanical precision and installation methods can be used to ensure that the camera has a certain positional relationship with a certain direction of the motion mechanism. However, in the following three situations: first, there is no direct connection mechanism between the camera and the moving mechanism; Positional relationship. Contents of the invention [0003] In view of the above problems, the embodiments of the present invention provide an included angle measurement method and device, and an included angle adjustment method and device, which can accurately measure the included angle betwe...
