Aluminum Large Calibration Board 3mm 5mm Dot Calibration Board

The Large-Sized Dot Calibration Board

The large-sized dot calibration board is a high-precision optical calibration benchmark for large field vision systems. Its core function is to correct lens distortion, establish precise mapping relationships between physical dimensions and pixels, and adapt to industrial large field of view detection, autonomous driving, 3D reconstruction, and other scenarios.

1. Core parameters and specifications
The maximum size that can be customized without splicing is 1680 × 3500mm, and some autonomous driving models can reach a single block size of 3m × 5m, supporting splicing to achieve a super large field of view coverage of over 10m. The diameter of the circular dots can be selected in various specifications such as 3mm and 5mm, and the graphic accuracy can reach 1 μ m. Some high-precision ceramic models can achieve an accuracy of 0.001mm.
2. Typical application scenarios
Large field industrial inspection: Internal and external parameter calibration of large format 3D scanners and multi camera global stitching systems to ensure micrometer level measurement accuracy of large-sized workpieces.
Automatic driving production line calibration: Equipped with a movable adjustable bracket, it can quickly adapt to the joint calibration of panoramic cameras and LiDAR for different vehicle models, greatly improving the calibration efficiency of mass production lines.
In fields such as aerial surveying and large space 3D reconstruction, a unified global coordinate reference is provided for large field of view perception systems.
