Visions Plus main products are calibration plate with ceramic and glass substrate materials. The calibration plate made of optical glass has stable chemical properties and high accuracy! This material is free of impurities and bubbles. It is the best material for high-precision calibration plate! The calibration plate of ceramic substrate has the characteristics of small thermal expansion coefficient, high hardness, good wear resistance, low thermal conductivity, good acid and alkaline resistance, and no reflection. Its good surface diffuse reflection treatment,this can solves the problem of reflection of glass calibration plate,especially under the condition of front light source in the application process. Customers can choose calibration plates of different materials according to their own needs. We have hundreds of standards and thousands of customized products to choose from, so as to realize one-stop purchasing of calibration plates.
To make sure the accuracy ,you need high precision checkerboard calibration targets.
The accuracy of the calibration plate is mainly determined by the manufacture processing technology, mainly including the following three types:
●Laser lithography process (accuracy within 1~3um): imported processing equipment such as high-precision lithography machine and optical coating machine. Commonly used processing materials include glass and ceramic. The production pattern can reach 1m, and the commonly used (glass) processing size is generally about 500mm:
●Screen printing process (precision 1-30um): high precision screen printing machine, precision screen plate and other processing equipment. The commonly used processing materials include glass, ceramic, metal plate and composite plate. The production range can reach 2m, and the commonly used processing range is 300-1000mm
●Laser drawing (accuracy 20-50um): laser marking machine processing equipment, commonly used processing materials include aluminum alloy plate, and the range is generally within 400mm
Laser cutting holes or some special shape to suit the mounting assembly.
FAQ:
What Is Camera and Lens Calibration?
Camera and lens sometimes distorted between the image and the real world.
The camera's internal characteristics like focal length, distortion, image center, and skew. We need to calibrate it to ensure the accuracy,calibration targets is one important tool,and the accuracy of the target is very crucial.
Why Is the Checkerboard Calibration Popular?
The checkerboard pattern including high precision lines,edges and corners.
And the checkerboard compatible with OpenCV software.(Open Source Computer Vision Library is an open-source computer vision library)
What is the checkerboard target application?
For machine vision, camera calibration, monocular calibration, etc.
What can be customized for the checkerboard calibration targets?
You can select the thickness of material,the accuracy, select the substrate material, decide the calibration plate width and height, how many squares would you like to print,would you like to print the pattern on back or front, the chart board shape you want...please feel free to contact us and tell us any of your requirements.
