OpenCV calibration targets on Glass
OpenCV calibtation target is a very popular test target with chessboard pattern 12*13 square grid array, the square sharp corner is high precision.OpenCV calibration software can easily obtain the calibration result data of the camera, Camera Calibration Using a Chessboard confirm the performance of the optical system, and determine the resolution of the camera lens. The classical checkerboard calibration board is compatible with the calibration algorithm of most image processing algorithms.
Glass OpenCV calibration target is a quartz glass material calibratoin board,quartz glass is a valuable material, has high temperature resistance, very small coefficient of thermal expansion, good chemical thermal stability, and bubbles, stripes, homogeneity, and birefringence can be comparable to ordinary optical glass. Therefore, it is an essential optical material with high stability for optical systems working in various adverse situations.Since the glass is transparent and reflective,we recommend to use it with background light source.If you have the front light source,you can choose our glass test target which is covered with a aluminum layer to avoid the transparency and reflection.Please be mentioned that we can offer many kinds of calibration targets including standard and customized version.
