An image data acquisition device

Abstract

The invention discloses image data acquisition equipment. The image data acquisition equipment comprises an equipment operating cabinet, image capture equipment and an optical refraction cavity, the image capture equipment and the optical refraction cavity are arranged on the equipment operating cabinet, the equipment operating cabinet is provided with a carrier loaded with an LED module to be detected, a detection station is arranged on the equipment operating cabinet, the incidence end of the optical refraction cavity corresponds to the detection station, and the emergence end of the optical refraction cavity corresponds to the image capture equipment. The image data acquisition equipment is simple and reasonable in structure, ingenious in design and small in size, the carrier can be supplied with electricity very conveniently, the carrier can circularly walk in the cabinet according to a set route, be automatically positioned and be accurately stopped at the detection station, and detection of the LED module is conducted. The distance between an image and a light catching lens is changeless, multiple pictures are acquired through a CCD image sensor under different optical filters, the distances between the pictures and the light catching lens are identical, calculation and comparison are conducted through software, and true colors of the image can be restored.

Description

technical field [0001] The invention relates to an image acquisition equipment technical device, in particular to an image data acquisition equipment. Background technique [0002] At present, in the existing image data acquisition equipment, for the equipment for testing LED modules, when testing the pass rate of the LED modules, it is necessary to place the LED modules in the image data acquisition equipment for power-on detection. [0003] In this way, it is necessary to set up a carrier for transporting LED modules, and it must satisfy the requirement that the carrier can walk automatically on the equipment running machine, satisfy the power transmission of the carrier, and the power transmission equipment cannot hinder the movement of the carrier. Moreover, it will not cause the size of the equipment running machine to be too large. An inspection station must be set on the equipment running machine to enable the detection of the LED module. The vehicle can be automatica...

AI Technical Summary

Problems solved by technology

[0004] Existing image processing equipment, such as cameras, cannot illuminate the true color of the image. Any lens will deviate when picking up light, which will cause the color of the photo to be different from the real color. Existing image processing equipment cannot Does not have the function of restoring the true color of the image

[0005] Its structure of existing photographic equipment all is that the lens is a retractable structure to adjust the focal length, and the structure of the CCD sensor (formally known as a charge coupling device) for collecting images at the rear is fixed, and there is no filter group in it, so This traditional image acquisition device is only used for taking pictures. For the application of restoring the true color of the image, for example, in the detection of LED display screen products, the existing image processing equipment is not competent
