Multiple Sensor Points
Ground-truth data for position, range and field of view for up to 12 sensors on your test vehicle.
The easy way to reference your sensor array technology
Our new Multiple Sensor Points functionality provides a quick and easy way for ADAS development engineers to validate the performance of individual sensors and ADAS technology. Up to 12 Sensor Points can now be defined in the RT‑Range software, which then provides additional real-time measurements whenever targets are present in the detection fields. The additional new RT‑Range measurements that allow real-time validation of multiple ADAS sensors are:
- Range from Sensor Point to target
- Percentage of target visible to the Sensor Point
- Percentage of field of view occupied by target
Multiple Sensor Point functionality can be used to evaluate RADAR- or LiDAR-based sensors for ADAS testing and development. In fact, it can be used to evaluate anything that has a fixed and definable field of view, such as the vehicle driver’s field of vision.
- Blind spot detection
- Autonomous vehicle validation
Saving you time
Vehicles with Blind Spot Monitoring, Intelligent Adaptive Cruise Control and Park Assist often feature multiple sensors distributed around the vehicle. This makes the job of ADAS engineers at Tier 1 sensor manufacturers and automotive manufacturers difficult, because to test and validate multiple sensors, it is necessary to reference the range and bearing to one or more targets relative to one or more sensors. To further complicate matters, it’s not uncommon for a single sensor to have multiple detection areas, ranging from wide angles at short range to narrow detection angles at long-range.
These challenges are easily solved by the RT‑Range software. With the introduction of Multiple Sensor Points, it’s easy to see in real-time which Sensor Points are currently tracking targets as measurements are only generated by each Sensor Point when one or more targets is present in its detection area. If a single target is present in the detection areas of several Sensor Points simultaneously, as you might expect with Blind Spot Monitoring, measurements are generated relative to each affected Sensor Point, so a full-picture of what each sensor sees is available.
As with existing RT‑Range measurements, reference data from the new Multiple Sensor Points feature is output in real-time via Ethernet and CAN bus, as well as being logged internally. The internally logged raw-data can also be reprocessed to allow for corrections in the configuration data if this is subsequently found to be incorrect, avoiding the need to repeat tests.
How it works
Before the RT‑Range can output measurements relating to any sensors fitted to a car, it must be told where they are and what they can see. This is done using the RT‑Range configuration software. The location of each Sensor Point is entered as an XY position offset with heading, relative to either the vehicle’s main Sensor Point or Polygon origin. Information about the sensor’s field of view angle and its minimum and maximum detection ranges is also entered to describe the detection area shown below.
In use, the RT‑Range will output measurements relating to each Sensor Point in real-time (and log them internally), whenever a target is present in that Sensor Point’s detection area. Detection areas are also shown in the Bird’s Eye View screen of the RT‑Range software, providing an additional tool for engineers to use.
