A1920 × 1080 25FPS, 2.4TOPS/W Unified Optical Flow and Depth 6D Vision Processor for Energy-Efficient, Low Power Autonomous Navigation

Abstract

This paper presents a unified 6D vision (3D coordinate + 3D motion) processor that is the first to achieve real-time dense optical flow and stereo depth for full HD (1920×1080, FHD) resolution. The proposed design is also the first ASIC that accelerates real-time optical flow computation. It supports a wide search range (176×176 pixels) to enable dense optical flow on FHD images with real-time 25fps/30fps (flow/depth) throughput, consuming 760mW in 28nm CMOS.
