US Patent 10574909 Hybrid imaging sensor for structured light object capture

A three dimensional imaging system includes a hybrid imaging sensor with infrared wavelength photoreceptors and visible wavelength photoreceptors integrated in one photoreceptor array. The three dimensional imaging system includes a bandpass filter to filter incoming light before the light is received at the hybrid imaging sensor to reduce crosstalk between the infrared wavelength photoreceptors and visible wavelength photoreceptors. The infrared photoreceptors receive infrared light provided by a structured light source and the visible wavelength photoreceptors receive ambient visible light. The hybrid imaging sensor collects infrared image data and visible light image data concurrently and/or simultaneously.
