Validating traffic sign recognition systems?

Product News, Software Releases

November 21, 2016

With the latest software update, the user interface of the OxTS RT-Range software has been enhanced to make real-time testing of vision based ADAS sensors, capable of detecting road signs or traffic signals, much quicker.

OxTS’ unique Feature Point technology means automotive engineers can create feature point files representing objects such as traffic lights or road signs and then load them into the RT-Range. The RT-Range can then output all standard range measurements (longitudinal range, lateral range, resultant range, time-to-impact etc.) once the feature point enters the sensors’ field-of-view. This gives users almost limitless freedom when planning realistic test scenarios for validating vision based ADAS sensors.

The new Feature Point survey tool now makes it even easier to collect these points before loading them into the RT-Range Hunter. The Feature Point Survey Wizard is designed to allow engineers to quickly and efficiently create Feature Point files using the real-time position information being output by the OxTS RT systems. Points can be created in response to a button press, or at regular time/distance intervals. Each new point is automatically numbered, and is fully defined using the current lat/lon, altitude and heading.

Setting up a sensor’s field-of-view in RT-Range software

 

Feature Point Surveys conducted over large areas can be carried out swiftly by mounting the RT system in a vehicle, and applying a displaced output to it. The displaced output should relate to a marked position on the vehicle perimeter, such as the front bumper. The driver can then simply drive up to points of interest until the displaced output point is touching the object, then press a button to create a Feature Point. All data points can be manually edited afterwards if it’s not possible to drive directly to the desired location. Once saved, Feature Point files can simply be uploaded to an RT-Range system.

The RT-Range is one of the most comprehensive and trusted solutions used globally for developing advanced driver assistance systems. Being able to conduct tests with multiple mobile targets, fixed targets as well as feature point targets such as road signs, is just one of the reasons the RT-Range is so popular with automotive engineers.
