High-precision light painting film, transparent PET material, thickness 0.18mm, flexible, good light transmission.
1. Features of film calibration board:
Transparent and flexible imported PET material with a thickness of 0.18 mm
Grid series film calibration board, high precision ±0.005mm, various sizes can be customized.
2. Scope of application:
Research units or special high-precision calibration tools in the field of vision, such as three-dimensional image measurement, three-dimensional reverse engineering, three-dimensional matching, three-dimensional reconstruction, etc., mainly obtain the data of camera calibration results through calibration software.
3. Function:
In order to correct lens distortion, determine the conversion relationship between physical dimensions and pixels, and determine the relationship between the three-dimensional geometric position of a point on the surface of a space object and its corresponding point in the image, it is necessary to establish a geometric model of camera imaging. In other words, the distortion of the lens itself is inevitable, and the calibration is used to improve the application performance of high-precision measurement and detection to achieve satisfactory accuracy.
4. Use:
Most software supports using solid circles or squares as marker points. In the process of high-precision camera calibration, most of the feature points are used as reference points, and the center position is accurately extracted through graphic fitting. And through the known calibration template parameters to eliminate the centroid caused by the projection.
