Live Demonstration: A 1920×1080 129fps 4.3pJ/pixel Stereo-Matching Processor for Low-power Applications

This demonstration presents an advanced stereo vision system with high energy efficiency. An ov5640 binocular camera, operating at a maximum of 30 frames/second with FHD (1920×1080) resolution, is employed to capture image pairs. A Spartan-7 FPGA rectifies these images with a calibration map matrix and then channels the pixel stream to the stereo-matching processor in a 28nm CMOS process for depth estimation. The resulting depth map, crucial for tasks like obstacle detection and navigation, is displayed in real-time on the monitor for low-power stereo vision applications.
