Product Introduction

This 905nm dedicated checkerboard calibration board is a composite standard calibration target designed for automotive LiDAR, autonomous driving perception, and machine vision system development. It uses a high-precision aluminum substrate combined with a professional diffuse reflection coating process. The black-and-white squares have fixed standard reflectivity, suitable for camera intrinsic parameter calibration, LiDAR and camera joint calibration, and multi-sensor fusion calibration testing.

 

Product Features

Matching LiDAR Standard Reflectivity: Optimized for the 905nm LiDAR wavelength, the black-and-white squares have fixed reflectivity of 5%/95%, satisfying optical camera imaging recognition while also enabling LiDAR echo intensity calibration, suitable for combined visual and LiDAR calibration.

 

Extremely High Geometric Accuracy: Square processing precision ±0.5mm; the 5mm aluminum alloy substrate is rigid, resistant to deformation, with flatness better than 1mm/m², ensuring calibration algorithm calculation accuracy and preventing calibration errors caused by deformation.

 

Stable Diffuse Reflective Coating: Professionally sprayed diffuse coating with no obvious specular reflection, effectively suppressing stray light interference, allowing stable imaging in both indoor laboratory and outdoor field testing.

 

Accompanying Sturdy Aluminum Profile Stand: Vertical stand with stable structure that does not easily shake; easy to install, standard height suitable for conventional vehicle-mounted perception device calibration, and supports flexible height adjustment.

 

Flexible Customization Service: Overall size, square edge length, and number of arrays can be modified as needed; the reflectivity of black and white squares can also be adjusted to accommodate other wavelengths.
