Aachen, Mai 2023: LiDAR technology (Light Detection and Ranging) offers high potential in machine perception for automated driving and currently available comfort and safety features due to its precise distance sensing and three-dimensional point cloud image generation. In the past years, growing number of new and established sensor manufacturers has been working on LiDAR sensors for automotive applications. This broad field of providers and the maturing of different technological approaches, lead to a wide variety of available sensor types and models based on the LiDAR principle. All these sensors are referred to as "LiDAR". However, the differences in the measurement principles, technology and components make the comparison of the specifications and evaluation of performance challenging.

In pursuit of a generally accepted test framework for LiDAR sensors, the innovative Aachen-based engineering service provider fka has joined forces with a number of committed partners to form a consortium in order to provide common guidelines for the characterization of sensors as well as a common and application-relevant evaluation/test concept. This is intended to provide a clear market overview and segmentation of LiDAR sensors based on the performance on point cloud level.

fka and its partners the German Institute for Standardization (DIN) and the Society of Automotive Engineers (SAE) have now successfully published the DIN SAE Specification 91471. This specification provides an evaluation methodology for LiDAR sensors, independent of the sensor design, its specification and technical approach. Its application to vehicle manufacturers and sensor suppliers enables a defined evaluation of sensor performance at the point cloud level, such as range, accuracy, precision and robustness of the measurement. In addition, the specification supports standardization of testing procedures. R&D facilities, hardware and software developers, proving ground operators, testing organizations and ADAS and AD system manufacturers will benefit from the newly created framework.

The DIN SAE Specification 91471 is available for download here.

Following the successful publication of the specification, fka is kicking off a follow-up project together with the DVN network. The project aims to investigate the performance evaluation of LiDAR sensors under adverse conditions such as adverse weather, contamination and interference from other LiDARs/light sources.
