I am planning to implement a project that involves object detection for cars, pedestrians, motorcycles, and bicycles, object tracking, semantic segmentation, lane detection, traffic sign detection, speed and distance estimation, and light source detection.
Which is the cheapest and most suitable Jetson board for this project?
For cost cosideration, you can refer to Jetson FAQ | NVIDIA Developer
For performance, you can check Technical Specifications from Jetson Modules, Support, Ecosystem, and Lineup | NVIDIA Developer
And a project sharing for your reference:
