The Video Interface Box X (VIB X) enables the direct injection of raw sensor data into camera ECUs. For this, the ECU is disconnected from the image sensor of the camera. In the next step, the image sensor is replaced by the Video Interface Box X. Using a high-performance graphics card, the raw data from the camera provided by the Camera RSI is generated from a simulated scenario and transferred to the Video Interface Box X via the DisplayPort output. The Camera RSI acts as a component of the CarMaker add-on Physical Sensor Models. The parameterization of the target format, including distortion features of the camera lens, is performed with the sensor dialogue in CarMaker. For visualization, IPGMovie and from CarMaker 10.0 onwards MovieNX are available.
In the FPGA of the Video Interface Box X, raw image data are converted into signals that correspond the real-world sensor, enhanced with real-time critical metadata and fed into the ECU via a suitable hardware interface. By utilizing powerful hardware, a low latency is achieved. Up to four cameras may be emulated. The Video Interface Box X therefore integrates perfectly into the HIL test setup from IPG Automotive. The Xpack4 system is an ideal complement to this hardware.
