Device for measuring structure by means of image

Abstract

The invention discloses a device for measuring a structure by means of image, belonging to the technical field of image measurement. The top of a machine body is provided with an image measurement assembly, and the four corners of the bottom of the machine body are respectively provided with a moving wheel component; a foot pad is installed in the middle of the bottom of the machine body; a marble pedestal is horizontally installed at the bottom of an inner cavity of the machine body; the marble pedestal is provided with a marble reflection base; a front lens support seat is installed at the right side of the marble reflection base, a rear lens support seat is arranged at the right side of the front lens support seat, and a big vision telecentric lens is connected between the front lens support seat and the rear lens support seat; the right end of the big vision telecentric lens is connected with a charge coupled device, and the charge coupled device is positioned at the right side of the rear lens support seat. The device adopts an optical reflection mirror design way, and the top-down construction way of the traditional camera lens is converted into a left-right lie-low structure, so that the space volume of the device is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of image measurement, in particular to a device for image measurement structures. Background technique [0002] Visual image detection is to use machines instead of human eyes for measurement and judgment. The machine vision system refers to converting the ingested target into an image signal through a machine vision product (that is, an image capture device, which is divided into two types: CMOS and CCD), and sending it to a dedicated image processing system. Digital signals; image intelligent recognition system software, etc., analyze these signals and perform various operations to extract the characteristics of the target, and then control the on-site equipment system according to the results of the discrimination. [0003] For the rapid detection of large-sized products, there are currently two types in the market: one is to use small field of view splicing measurement. In this method, the system is equ...

Problems solved by technology

[0004] The object of the present invention is to provide a device for image measurement structure to solve the problem of long measurement time and low detection efficiency of the small field of view assembled measurement proposed in the above background technology, while the large field of view fast measurement is mostly a hardware structure, and the camera And the lens is constructed from top to bottom. This kind of hardware erection leads to bulky equipment and difficult transportation and handling.
