Method for controlling movement of worktable of automatic image measuring instrument

Abstract

The invention discloses a method for controlling movement of a worktable of an automatic image measuring instrument, which comprises the following steps of (1) performing image focusing for obtaining a clear image; (2) setting an anchor point through pressing down a middle button of a mouse when a cursor is at a proper position of an image area; (3) pressing the middle button of the mouse and moving the cursor, generating a direction vector arrow which is composed of the anchor point and the current cursor above the image, wherein the vector arrow performs real-time change along with position change of the cursor, thereby forming an effect which is similar with an effect in pulling a rubber band; (4) making the worktable move in a manner that the length of the vector arrow after calibration is utilized as speed and the arrow direction is utilized as a movement direction, and changing the movement speed and the movement direction in real time according to the change of the vector arrow; and (5) releasing the middle button of the mouse for stopping movement of the worktable. According to the method of the invention, movement direction and movement speed are defined by means of the direction and the magnitude of the vector arrow generated by pulling, and manual input of the speed is not required. Furthermore the movement speed and the movement direction can be changed in real time, thereby facilitating definition for characteristic positions of a to-be-measured workpiece and improving measurement efficiency.

Description

technical field [0001] The invention relates to the technology in the field of automatic image measuring instruments, in particular to a method for an automatic image measuring instrument to control the movement of a workbench. Background technique [0002] Image measuring instrument, also known as precision image surveying instrument, overcomes the shortcomings of traditional projectors and is a new type of high-precision, high-tech measuring instrument integrating optical, mechanical, electrical, and computer image technologies. The optical microscope performs high-magnification optical magnification imaging on the workpiece to be measured. After the enlarged object image is sent to the computer through the CCD camera system, it can efficiently detect the contours and surface shapes, dimensions, angles and positions of various complex workpieces, especially Microscopic inspection and quality control of precision parts. The measurement data can be directly input into AUTOC...
