High-speed recording for complex ADAS data

0

One of the main challenges facing engineers developing ADAS and AD applications is the need for very high-speed data recording and precise timing of data events. To assist in this, specialist B-plus has launched its BRICK2 recording and computing platform.

According to the company, cross-system and cross-interface accuracy and synchronicity of recorded measurement data during test drives of AVs is extremely important for efficient test processes. Incomplete and out-of-sync data require additional, cost-intensive and time-consuming effort for their post-processing.

To prevent such problems arising, the BRICK2 system offers a clock synchronization mechanism, which precisely time stamps each incoming data package. To achieve this, a Cross-platform Ethernet with PTP (802.1AS-2020) serves as an exact time source, or alternatively, a hardware GPS-receiver and serial ports (NMEA) built into the system can provide time information with nanosecond accuracy.

The company also said the system offers both efficiency and performance thanks to a permanent writing speed of 24Gb/s. An example of the benefits of this capability is that one system can process up to six camera sensors with an eight-megapixel resolution. Furthermore, larger measurement setups with multiple sensors can be realized with a linked BRICK cluster.

The company noted that a wide variety of modules are needed for holistic acquisition of all measurement data in a test scenario. This calls for an interaction of various components which are not necessarily easily interfaced. B-plus said its system aids the integration of such disparate components by acting as a central node for all measurement data. Additionally, the open platform nature of the system enables customers to integrate their own software.
