METHOD FOR RECOGNIZING A TRAFFIC SIGN BY MEANS OF A LIDAR SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240134049 titled 'METHOD FOR RECOGNIZING A TRAFFIC SIGN BY MEANS OF A LIDAR SYSTEM
Simplified Explanation
The patent application describes a method for recognizing a traffic sign using a lidar system that senses the intensity level of light signals, including multiple light signal points. The method involves:
- Ascertaining the reflection degree of each light signal data point
- Comparing the reflection degrees with a predefined reflectivity limit value
- Marking points exceeding the limit as belonging to a retroreflector
- Determining the size of the retroreflector from the marked points
- Recognizing the retroreflector as a traffic sign based on its size

Original Abstract Submitted
a method for recognizing a traffic sign by means of a lidar system. the lidar system is designed to sense an intensity level of a light signal detected in the lidar system, the light signal including a plurality of light signal points. the method includes the following steps: a) ascertaining a degree of reflection of each light signal data point from the intensity level thereof; b) comparing the ascertained degrees of reflection with a predefined reflectivity limit value; c) if the predefined reflectivity limit value is exceeded, marking the corresponding light signal data point as belonging to a retroreflector; d) ascertaining a size of the retroreflector from the marked light signal data points. e) recognizing the retroreflector as a traffic sign as a function of the ascertained size of the retroreflector.
