Overview

The logiRECORDER Automotive Video Data Logger is a user-friendly, all-in-one automotive video and network data logger that sets the new standard for design and validation of vision-based Advanced Driver Assistance and Autonomous Driving (ADAS/AD) systems. It operates by tapping between the real vehicle’s camera installation and the Electronic Control Units (ECUs) to enable noninvasive and low-latency recording of camera video, and network sensory and ECU data.

Applications

Non-invasive test and validation of Advanced Driver Assistance and Autonomous Driving (ADAS/AD) systems in real traffic situations Recording of the real-world road conditions for use in the laboratory, i.e. in the HIL simulations Development of new ADAS/AD algorithms and systems

Features

  • Enables simultaneous recording of up to twelve(12) uncompressed video camera inputs and the data from various in-vehicle networks
  • Inserts between cameras and ECUs to ensure noninvasive low-latency video capture from the real vehicle s camera installation (As Is!)
  • Simulates the complete vehicle camera system by playing back the recordings in Hardware-in-the-Loop HIL tests on the developer s desk
  • The playback saves original video frame rates, resolutions and phase relations
  • The default video interface can be modified:
    • TI®, FPD Link-III (DS 913/914 RX/TX), resolution 1280x800@30fps, YCbCr 4:2:2
    • aux HDMI input 1280x1024@60fps
  • Records automotive network data parallel to video : CAN, LIN, FlexRay, UART, DIG I/O, GP
  • Recordings are stored with a central timestamp
  • User-friendly PC application enables full control of the HW configuration, recording and playback
  • Can be configured for the self-standing operation in the test vehicle
  • Supports standard and event-triggered recording of video and data before and after the trigger
  • Triggers and filters can be setup as signals and messages from the vehicle databases
  • Currently supported vehicle databases: CAN XML DBC, LIN LDF, FlexRay FIBEX
  • Industry standard formats of the log files:
    • video in the YUY2 AVI format
    • networks data in ASC file format
  • External trigger IOs enable integration with third-party test equipment in the test vehicle
  • Enables control HDMI monitor output while recording and during the playback
  • Four(4) portable SSD Disks (FAT32, up to 8 TB combined) enable hours of recordings
  • The removable SSD SATA disks can be plugged in a PC for easy video and network data transfer
  • Rugged and actively cooled housing enables reliable test vehicle installations
  • Integrates separated video inputs and outputs to avoid constant re-cabling
  • Modular architecture based on the Xilinx®, FPGA/SoC enables customizations
  • Documentation and tech support (e-mail)
