Problems solved by technology
[0006] The object of the present invention is to provide a drum-type color calibration detection platform base body, calibration platform and detection platform, to solve the problem that the light source and the camera are easy to shake when the calibration platform is calibrated and moved to the detection platform, and there is no color on the detection platform. Set up a reference object corresponding to the calibration platform, resulting in a change in the relative position of the camera and the light source, resulting in inaccurate collection of the color image of the printed matter and affecting the detection results

The invention discloses a drum-type color calibration and detection platform base body, a calibration platform and a detection platform. The drum-type color calibration and detection platform base body comprises a box body, a light source and a camera arranged at the top part of the box body, wherein a slit is formed in the bottom part of the box body, two sides of the box body are provided with bases, detection roller installing plates and a calibration roller base are arranged on each base, and a detection roller base is arranged on each detection roller installing plate; a calibration roller assembly is installed on the two bases to form a drum-type color calibration platform, the color of the camera is calibrated, relative positions of the camera and the light source are corrected, the calibration roller assembly is dismantled after the calibration is completed, then a detection roller assembly is installed between the two bases to form a drum-type color detection platform, and the drum-type color detection platform is used for acquiring color images of printed matters. According to the drum-type color calibration and detection platform base body, the calibration platform and the detection platform, the box body comprising the camera and the light source does not need to be moved, the relative positions of the camera and the light source are ensured to be unchanged, and the accuracy of color detection of the printed matters is improved.
Description
technical field [0001] The invention relates to the technical field of printed matter detection equipment, in particular to a drum-type color calibration detection platform substrate, a calibration platform and a detection platform. Background technique [0002] The printed matter automatic detection system has the advantages of high speed, stability, and all-weather operation, which can effectively avoid the missed detection and wrong detection caused by the traditional manual visual inspection method due to individual differences, fatigue and other factors. Therefore, the printed matter automatic detection system is widely used in various industries. [0003] The traditional automatic printing color detection system mostly adopts the contact non-online detection method, through the contact of the color detection instrument with the printed matter, the color image of the contact point is obtained, and then the sample is compared with the color image of each contact point, an...
