The 3D camera is using infrared active stereo depth and red/green/blue sensor, and a VCSEL projector.
Integrated in a compact aluminum case, the Intel RealSense D435 is an intelligent USB-C powered 3D active infra-red global shutter stereo depth camera. It combines a conventional red/green/blue (RGB) color sensor, a vertical-cavity surface-emitting laser (VCSEL) projector and left- and right-side imagers for stereo vision.
The 3D camera has a minimum depth of 0.2m and can scan environments up to 10m wide with a resolution depth of up to 1280x720 at 90 frames per second (fps). The system uses a 28nm Intel D4 vision processor for processing complex depth data in real time and a Realtek color image processor.The infrared laser projector is tiny, measuring only 2.7mm x 1.8mm, uses VCSEL technology and can record 60fps. Omnivision supplies the three image sensors; a CMOS 1080p RGB sensor and twin 1-megapixel sensors for the left and right side imagers.The components and sensors are contained in ball grid array (BGA) and wafer level packaging, all mounted on two single-sided boards whose total surface area is less than 20cm².
Based on a complete teardown analysis of the RealSense D435, the report provides high definition pictures of the vision processor, VCSEL IR projector and image sensor dies as well as the bill-of-material (BOM) and the manufacturing cost of the depth module.
