Development of a sensor image evaluation system for automotive applications

We have developed an experimental platform that allows for algorithm testing through images captured and imported to a PC.
By utilizing general-purpose interfaces and modules, we were able to significantly reduce development costs.

System overview

System requirements

Customer request

  • We have designed and developed an experimental platform for system validation and testing, using CameraLink as the image sensor interface for variable imaging speeds linked to the vehicle's speed.
  • The platform enables algorithm testing using images captured and imported to a PC, which can be integrated into the system in the future.
  • These images include location information and frame drop-free confirmation.
  • To enable on-road testing in an automobile, we have optimized the system to be as compact as possible. It can be easily connected to a small PC through USB.

Proposal contents (feature)

  • To minimize costs, we have incorporated FPGA vendor-provided IP wherever possible in the system design.
  • For connecting the PL and PS sections, we utilized AXI bus IP, which not only helped us cut costs but also reduced risks associated with bus design in SoC development. Additionally, we leveraged general-purpose interfaces such as UART and DDR to further reduce development expenses.
  • For cost-effectiveness, we used off-the-shelf modules for GPS and DDR memory as the projected manufacturing quantities were only a few to several units.
  • We optimized the ratio of virtual verification (logic simulation) to actual testing by conducting machine function evaluations alongside logic simulations to take verification costs and work delays into account.
  • We believe that agile development is more suited for this project's development process than waterfall development.
