Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance and automated driving systems face high false-positive rates due to ghost objects caused by reflections or multiple reflections, which limit the functionality and reliability of environmental sensors.
Innovation Solution
A method for evaluating sensor data that involves object detection and filtering, utilizing a trainable classifier and database access to determine surface properties of objects, allowing for the identification and verification of ghost objects and improving sensor reliability through surface property analysis.

If sensor data evaluation is performed without additional verification, then processing speed is maintained, but accuracy and reliability of environmental sensors are reduced
Solution Approach 1:
The patent introduces an intermediary verification mechanism using surface property databases. Instead of directly validating detected objects against raw sensor data alone, the system introduces surface property information as an intermediary layer. This intermediary data from the database serves as additional verification evidence, allowing the system to improve measurement precision and sensor reliability while maintaining efficient processing through database lookups rather than complex real-time analysis.

AI summary
The invention relates to a method for evaluating sensor data, wherein sensor data are determined by scanning an environment by at least one sensor, and based upon the sensor data an object detection for determining objects from the sensor data and an object filtering are carried out, surface characteristics of at least one object being recognised and/or the surface characteristics of at least one object being determined by means of an access to a database. The invention further relates to a control device. Figure
