Technical Field

[0001] The utility model relates to the technical field of image measuring instruments, in particular to an auxiliary clamp for an image measuring instrument. Background Art

[0002] The image measuring instrument is based on CCD digital images, relying on computer screen measurement technology and the powerful software capabilities of spatial geometry calculation. It can quickly read the displacement value of the optical ruler, and instantly obtain the desired results through software module calculation based on spatial geometry, and generate graphics on the screen for the operator to compare the image and the shadow, so as to intuitively distinguish the possible deviations in the measurement results. The image measuring instrument is a high-precision optical image measuring instrument composed of a high-resolution CCD color lens, a continuously variable magnification objective lens, a color display, a video crosshair display, a precision grating ruler, a multi-function data processor, data measurement software and a high-precision workbench structure.

[0003] When performing image measurement, the product is usually placed on the measuring table of the image measuring instrument, and the measurement is carried out through the lighting under the measuring table and the measuring head on the measuring table.
