Autonomous Driving Data Acquisition Solution Based on Jetson+FPGA+GMSL+AI

Solution Introduction

To develop more complex and advanced autonomous driving systems, extensive sensor data and ground truth data must be collected through road tests to validate sensor functionality and train autonomous driving algorithms.

Accurately and efficiently collecting, storing, and transferring data generated by various high-bandwidth sensors on vehicles requires a data acquisition system with multi-sensor acquisition capabilities and powerful computing performance. Such a system must ensure stable device performance, offer flexible configuration and expansion, and provide flexible software-level configuration and data processing to enhance the efficiency and quality of data collection.

Addressing the extensive sensor data acquisition and validation needs during the development and testing phases of autonomous driving systems, Sienovo introduces a specialized autonomous driving data acquisition solution. This solution includes the necessary hardware, software, and customized services to help improve R&D efficiency.
