Dynamic Test Stand - DTS

A fully automated test stand for automotive cameras and sensors

Dynamic Test Stand


As autonomous driving assistance systems continue to develop, it has become crucial to test the safety and effectiveness of these camera systems. The Dynamic Test Stand has the unique ability to check an automotive camera for its capability of detecting and differentiating multiple objects within the cameras field of view.

This device has effectively created a new way of testing automotive image quality by measuring contrast detection probability (CDP). New technology in the automotive sector means traditional KPIs such as SNR have less importance and new measurements such as CDP are needed to address the latest technology.

Essentially, the DTS can test an extensive dynamic scene as opposed to a synthetic scene all within a lab environment. In the test lab, it can precisely recreate driving conditions that would be much harder to duplicate in an unpredictable outdoor setting.

While an outdoor setting is still possible, there are few options for analysis software to evaluate the miles of generated data. A breakthrough with the DTS has been the development of CDP evaluation software that can quickly analyze the data to see the object detection probability of the camera.

Generate and export individual testing sequences on your pc from any location.

Run test sequence
2Device Testing

Import and manage sequences and receive live updates from the DTS device itself.

Analysis results

Evaluate, compare, export and share test results with different developers and manufacturers.

Hardware Features

The DTS device itself incorporates advanced hardware and LED lighting to create an all in one testing solution for automotive cameras. With one device, it is possible to run a test for contrast detection, color separation, modulated light mitigation (flicker) and motion artifacts (blurring).

One of six contrast detection boxes
Contrast Detection Probability (CDP)

Test for CDP with the six separate contrast detection boxes and 216 different intensities. Analyze the cameras ability to detect and differentiate multiple objects in its field of view.

One of two color separation boxes
Color Separation Probability (CSP)

Test for CSP using two separate color boxes powered by LED lighting technology. Discover how well the camera can separate multiple and similar colors in its field of view.

One of six contrast detection boxes
Modulated Light Mitigation Probability (MMP)

Check the response of the camera to different intensities using flicker mode on the six contrast boxes. There are also four single LED lights for measuring local flicker.

One of two color separation boxes
Motion Artifacts (Blurring)

Using two rotational off-axis edge targets located in front of the color boxes, measure how well the camera responds to various blurring and motion effects.

Distortion correction
Hardware distortion compensation

Compensate for camera distortion by adjusting the whole front grid of the device ensuring a square in the hardware is a square in the image.

Touch screen control
Touch screen control

Control the device on site with the touch screen display monitor. Quickly incorporate the DTS into any lab setting or production line.

Software Features

The DTS software is used to generate sequences, control the hardware and evaluate the test results. What makes this software invaluable is its ability to produce the test sequences and then evaluate the results, all of which is possible from a separate location than the device itself. This dynamic gives the research and development team much more freedom when testing.

DTS Sequence Generator

DTS-Sequence Generator

Establish the individual testing sequences

This software can generate testing sequences using drag and drop control. It also controls step parameters, simulates the sequences and is capable of importing/exporting sequence files (XML-Format).

DTS control software

DTS-Control software

Use the hardware to manage and run the sequences effectively

This part of the software controls the sequence timeline on site. It also can correct the field of view, log (sensor tracing) and control the DTS-Calibration routine.

DTS Sequence Generator

DTS-Evaluation software

Gather and quickly evaluate the test results

The evaluation software can quickly and efficiently analyze the results of the testing sequences. Use this software to evaluate CDP, CSP, MMP and motion artifacts.


Technical Data

The DTS is a fully automated, highly intense illuminator based on LG3 technology. Measure multiple performance indicators in a single generated sequence including, Contrast Detection Probability (CDP), Color Separation Probability (CSP), Modulated Light Mitigation Probability (MMP), and motion artifacts.

CDP is measured using six different OECF transparent test charts made up of 216 greyscale patches and a dynamic range of 120 dB. CSP uses two integrated CAL2 devices to provide multispectral light sources based on iQ-LED technology. MMP utilizes flicker mode with a flicker frequency of 10 – 500 Hz and a flicker duty cycle. Motion artifacts are measured using two rotating slanted edge test charts.

This device can compensate for varying levels of distortion depending on the distortion of the DUT. It also exhibits a relative illumination stability of > 98% and an active service life of 10,000 hours.

Currently, the DTS-Evaluation software is available for the CDP measurements. Future developments will include the addition of CSP, MMP, and motion artifacts evaluation software. These additions will be available during the first software updates.
