In machine vision applications, the use of a calibration board is very necessary, because for accuracy measurement, the distortion of the lens itself is inevitable, and at the same time it needs to achieve the accuracy of customer satisfaction, so the image itself is required to be very true and accurate, otherwise the software level No matter how high, it is also based on the processing of the image with errors, and the final result must be a large error. High-precision system calibration is the prerequisite and foundation for machine vision systems to make precise measurements and inspections. It can improve the accuracy of your measurement system in two steps. The first is error measurement and evaluation. The high-precision calibration system acquires the images collected by the ultra-precise professional image calibration board under your machine vision system environment, and cooperates with professional calibration algorithms to achieve this process. The system can accurately draw The error value at any position within the field of view, and based on this error data, evaluate the accuracy level of the machine vision system. The second step is the correction and compensation of the error image. The calibration system obtains the error data according to the first step to perform position correction and compensation on each pixel information on the image. This process involves image translation, rotation, interpolation, reconstruction, brightness compensation, etc. A sophisticated image algorithm, the corrected and compensated image can more accurately reflect the actual situation of the measured object, and achieve the purpose of precision measurement and detection. Any machine vision system involving position and dimensional accuracy must be calibrated, but the calibration method can be selected appropriately according to the application field. In general, the accuracy of the calibration system should be on the same order of magnitude as the accuracy requirements of the measurement system, and the calibration error is not greater than A measurement unit, for example, the accuracy of the measurement system is required to be ± 50 microns, then the accuracy of the calibration system must reach the level of 10 microns, and the error of the calibration system cannot be greater than 10 microns.
