In the application of machine vision, it is very necessary to use a OpenCV 20mm Ceramic Calibration Board, because for accuracy measurement, the distortion of the lens itself is inevitable, and at the same time, the accuracy of customer satisfaction needs to be achieved, so the image itself is very real and accurate, otherwise the software level is high, which is also an error based on image processing, and the final result must have a big error.

High precision system calibration is the premise and foundation of accurate measurement and detection of machine vision system. The accuracy index of the whole measurement system can be improved through two steps.

The first is error measurement and evaluation. The high-precision calibration system realizes this process by combining the images collected by the professional image OpenCV 20mm Ceramic Calibration Board accurately depicted in the machine vision system environment with the professional calibration algorithm. The system can accurately obtain the error value at any position in the field of vision, and evaluate the accuracy level of the machine vision system according to the error data.

The second step is to correct and compensate the wrong image. The calibration system obtains error data according to the first step, and conducts position correction and compensation for each pixel information on the image. This process involves many precise image algorithms, such as image translation, rotation, interpolation, reconstruction and brightness compensation. After correction and compensation, the image can more accurately reflect the actual situation of the object to be measured, so as to achieve the purpose of accurate measurement and detection.

Any machine vision system involving position and dimension accuracy must be calibrated, but the calibration method can be selected according to different application fields. Generally speaking, the accuracy of the calibration system shall be the same as that of the measurement system, and the calibration error shall not exceed the measurement unit. If the accuracy of the measurement system is required to be ± 50 microns, the accuracy of the calibration system must reach 10 microns, and the error of the calibration system cannot exceed 10 microns.

Machine vision technology is changing with each passing day. Zhixing focuses on the R&D and production of machine vision technology. At present, it specially provides laser sensors for welding robots, endows them with sensing functions, and solves the problems of mold deviation, welding deformation or robot walking path planning.

Customer FAQs

1. Can your company customize calibration plates?

Answer: Yes

2. What is the material of your calibration plate?

Answer: quartz glass, glass, ceramics, honeycomb aluminum, pure aluminum, acrylic acid, film

3. What does high precision mean?

Answer: High precision refers to the precision of distance error between pattern angles

4. What is the accuracy of your calibration plate?

Answer: Calibration plates with different accuracy can be customized according to your needs. ± 0.001 mm/± 0.01 mm/± 0.1 mm

Material is also a major factor in determining accuracy. Therefore, high-precision materials are glass, ceramics, quartz glass and film, which can be used as calibration plates of different sizes. Medium precision materials can be used as glass, honeycomb aluminum and acrylic, while low precision materials can be used as glass, honeycomb aluminum and pure aluminum.

5. I want to make high-precision products. What materials and sizes can I make?

Answer: glass, ceramics, quartz glass and film. If you want to make high-precision calibration plates above 200mm, we suggest you make glass. It is the most practical and preferential material. If you cannot use reflective materials, we recommend that you purchase our self luminous calibration plate, which can effectively prevent reflection.
