1. Features of Film Calibration Board:
Made of transparent, bendable imported PET material (0.1mm thick). This chessboard series film calibration board offers high precision (±0.01mm), and various sizes can be customized.
2. Application Scope:
It is a high-precision calibration tool for research institutions or the machine vision field. It is used in 3D image measurement, 3D reverse engineering, stereo matching, 3D reconstruction, etc. It mainly obtains camera calibration result data via calibration software.
3. Function:
Used to correct lens distortion, determine the conversion relationship between physical size and pixels, and establish the correlation between the 3D geometric position of a point on the surface of a spatial object and its corresponding point in the image (requiring the construction of a camera imaging geometric model). For precision measurement, lens distortion is unavoidable; calibration is applied to improve the performance of high-precision measurement and inspection to achieve satisfactory accuracy.
4. Usage:
Most software supports solid dots or squares as markers. In high-precision camera calibration, feature points are mostly used as reference points; the center position is accurately extracted via graphic fitting, and the centroid deviation caused by projection is eliminated using known calibration template parameters.
