LiDAR Testing Solution

Overview

With the rapid advancement of intelligent driving technology, LiDAR, as a core sensor for environmental perception, plays a direct role in ensuring driving safety and the reliability of the driving experience. To standardize the performance evaluation of this critical device, China has established the national standard GB/T Performance Requirements and Test Methods for Automotive LiDAR (referred to as GB/T 45500). Building on years of technological expertise, Yanding Technology has introduced an integrated LiDAR testing system compliant with this standard, providing comprehensive and precise automated testing support for the industry.

Details

I. Interpretation and Applicability Scope of the GB/T 45500 Standard

The GB/T 45500 standard is China's first national-level technical specification for the performance testing of automotive LiDAR. It systematically defines performance metrics and test methods for LiDAR in areas such as ranging, field of view, angular characteristics, and reflectivity. This standard aims to unify industry testing benchmarks and enhance the reliability, safety, and consistency of LiDAR products.

Applicable Equipment: The standard primarily targets various types of automotive LiDAR devices, including mechanical, solid-state, MEMS, and other LiDAR systems. It is applicable to testing needs throughout the entire product lifecycle, from R&D verification to production quality inspection.

II. Comprehensively Covered Test Items

Strictly based on the GB/T 45500 standard, the Yanding system supports the automated testing of the following key performance indicators:
