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 18546005 titled 'METHOD FOR RECOGNIZING A TRAFFIC SIGN BY MEANS OF A LIDAR SYSTEM

Simplified Explanation

The method described in the abstract is for recognizing a traffic sign using a LiDAR system. Here is a simplified explanation of the patent application:

• Ascertaining the degree of reflection of each light signal data point
• Comparing the degrees of reflection with a predefined reflectivity limit value
• Marking the data points that exceed the reflectivity limit as belonging to a retroreflector
• Determining the size of the retroreflector from the marked data points
• Recognizing the retroreflector as a traffic sign based on its size

Potential Applications

This technology could be applied in autonomous vehicles for improved traffic sign recognition and road safety systems.

Problems Solved

This technology solves the problem of accurately identifying traffic signs in various lighting conditions and environments.

Benefits

The benefits of this technology include enhanced road safety, improved navigation for autonomous vehicles, and better overall traffic management.

Potential Commercial Applications

The potential commercial applications of this technology could include integration into autonomous vehicles, traffic management systems, and road infrastructure monitoring.

Possible Prior Art

One possible prior art for this technology could be existing LiDAR systems used for object detection and recognition in various industries.

How does this technology handle different types of retroreflectors, such as those with varying shapes or materials?

The method described in the abstract focuses on recognizing retroreflectors as traffic signs based on their size. However, it does not specify how it would handle retroreflectors with different shapes or materials. Further research and development may be needed to address this issue.

What are the limitations of using LiDAR technology for traffic sign recognition in real-world scenarios?

While the abstract outlines a method for recognizing traffic signs using a LiDAR system, it does not discuss the potential limitations of this technology in real-world scenarios. Factors such as weather conditions, occlusions, and the presence of other objects on the road could impact the accuracy of traffic sign recognition. Further testing and validation would be necessary to assess the technology's performance in various conditions.

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.
