Description

Technical Field

[0001] The utility model relates to the technical field of image measuring instruments, in particular to an image measuring instrument with a protective structure. 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] However, the measuring probe on the common fully automatic image measuring instrument does not have a protective function. When not in use, the measuring probe is always exposed and there is nothing to protect it. As a result, the measuring probe is easily damaged by collision, which at best reduces the accuracy of measurement and at worst causes damage to the measuring instrument, greatly reducing the service life of the image measuring instrument and causing great inconvenience to the user.
