Large Scale 3D Calibration Board

The large-sized 3D calibration board is a core calibration tool in fields such as machine vision, 3D reconstruction, and autonomous driving, which can achieve precise calibration of spatial coordinate systems and ensure measurement and imaging accuracy.

1. Core Features:Supporting various substrates such as glass, ceramics, and metals, the highest accuracy can reach ± 0.001mm, and some large-sized specifications can reach 800 × 960mm or even 2500mm levels.
Adapting to extreme working conditions, some products can maintain dimensional stability in environments ranging from -40 ℃ to 120 ℃, meeting the requirements of automotive and aerospace grade use.
2. Mainstream application scenarios:

Industrial vision and 3D scanning: used for distortion correction of 3D scanners and multi camera cameras to ensure the accuracy of high-precision dimensional measurement.
In the field of autonomous driving: adapt to the calibration requirements of ADAS and LiDAR, and complete the joint calibration of onboard cameras and radars.
In the fields of aerospace, architectural surveying, VR/AR, etc., it can also be used for precision calibration of large field of view measurement equipment.
