OPT Speckle Structured-Light RGB-D Cameras
A binocular speckle/RGB-D 3D camera family for large field-of-view depth and color acquisition, with LSA1 series covering wide-area logistics, depalletizing, picking, and millimeter-level positioning.
The speckle structured-light camera family is built around binocular depth sensing with active speckle projection. It is positioned for large field-of-view imaging, synchronized RGB-depth acquisition, and cost-sensitive industrial robot vision where millimeter-level depth is enough but speed and coverage matter.
Principle
The camera projects a speckle pattern onto the scene, captures the deformed pattern from two CMOS sensors, and reconstructs depth through stereo matching and triangulation. The output can include RGB image, depth map, and colored point cloud.
Product strengths
The source deck highlights large field-of-view coverage, low cost in wide-area scenarios, RGB image and depth map output from one acquisition, compact body design, high frame rate up to 20 FPS, and anti-ambient-light capability above 30000 lx.
Stereo algorithms
The RGB-D algorithm stack uses stereo rectification, cost computation, cost aggregation, disparity estimation, subpixel refinement, flying-point removal, consistency checks, uniqueness checks, smoothing, and 2D/3D coordinate alignment.
Applications
Primary applications include logistics bin picking, dynamic parcel sorting, depalletizing, large-format volume measurement, PACK packaging, sheet-metal cutting localization, and robot obstacle-aware guidance. The source deck reports logistics cases with large field of view, fast point-cloud output, RGB-assisted AI recognition, and high-throughput picking.
