The only difference between D435i and D436 is the RGB camera. D436 has 1MP Global Shutter wide FOV of 87° × 58° RGB camera. The D435i RGB camera is 2MP Rolling Shutter standard FOV of 69° × 42°.
The RealSense™ Depth Camera D436 features a broad field of view global shutter D430 optical module, with a matching global-shutter RGB sensor synchronized with the depth sensors.
A global-shutter RGB sensor is optimized for dynamic environments involving moving objects or quickly changing viewpoint, such as when a robot or AMR rotates along its vertical axis. Its higher sensitivity delivers more reliable image quality in low-light or mixed lighting conditions and bright light.
To enhance the synchronization between the depth and RGB images, all D436 sensors are global shutter with matching FOV. D436 is equipped with 1MP global-shutter depth and RGB sensors, ~90° field of view, IMU bundled with our onboard RealSense™ Vision Processor D4 (Board V3).
