Scientific Breakthrough |
The 3D image recording system adopts Chaotic LiDAR to capture high-accuracy depth image with 1550nm eye-safe APD arrayToF circuits. By including RGB camera, new calibration/alignmentAI-based super-resolution techniques can increase spatial resolution of depth imageconstruct 3D image. Compared to the advanced Intel RealSense L515, the proposed system achieves higher accuracy (1cm@20m vs 1.55cm@9m)angular resolution (0.0125°x0.0125° vs 0.073°x0.071°) in both indoor/outdoor environments with an efficient eCNN core (7TOPS/W) for various image/video AI processing applications.
