Nanophotonic Chips
Our in-house nanophotonic chips provide the hardware foundation for structured light, mToF and other sensing technologies.
Technology
DEPTRUM develops optical sensing, intelligent perception and perception computing technologies across the full stack—from chips and optical hardware to software, algorithms and complete solutions.
Visual Perception Across the Full Stack
Three complementary fields turn optical information into the ability to perceive, understand and compute—bringing visual perception to real-world applications.
Structured-Light 3D Reconstruction
Actively projected speckle patterns capture spatial information to reconstruct objects in 3D.
Stereo 3D Reconstruction
Active stereo imaging measures binocular disparity to reconstruct a scene in 3D.
sToF 3D Reconstruction
Structured light and ToF combine close-range accuracy with long-range detection.
Palmprint and Palm Vein Imaging
Palmprint and palm vein images provide the visual data for identity authentication.
Area-Array Point Cloud SLAM
An area-array depth camera captures continuous 3D point clouds. Spatial feature extraction, matching and pose estimation enable real-time localization and mapping for autonomous robot navigation.
Stereo Visual SLAM
Continuous stereo imagery supports real-time localization and mapping through stereo matching, feature tracking and pose estimation.
3D Facial Recognition
Combines 2D facial texture and 3D facial structure for identity recognition. 3D liveness detection distinguishes real faces from spoofing attempts to strengthen authentication security.
Palmprint and Palm Vein Recognition
Dual-modal palmprint and palm vein biometrics use visual algorithms for feature extraction, matching and contactless identity authentication.
Gesture Recognition
Vision captures hand position, pose and motion, while AI algorithms identify gestures and movements for natural, vision-based interaction.
RGB-D Sensor Fusion
Combines color and texture from RGB images with spatial information from depth data to give robots integrated RGB-D vision.
Structured-Light Soft-Core Computing
Hardware–software co-design implements core structured-light computations as a soft core, improving 3D processing efficiency and enabling lightweight, real-time spatial computing at the edge.
CPU and Memory Optimization for SLAM
Algorithmic advances and engineering optimization address the compute and memory limits of embedded platforms, enabling real-time localization and mapping with as little as one A53 core and 100 MB of memory.
Integrated Image, 3D and Perception Processing
Integrates image processing, 3D computation, AI recognition and SLAM to reduce data transfers and redundant computation—processing visual input into usable perception outputs entirely at the edge.
