Metrological qualification of the intel D400™ active stereoscopy cameras

In January 2018, Intel released the RealSense RS400™ generation of Three-dimension (3D) computer vision devices based on Active Stereoscopy technology. It includes RGB-D modules and image processing hardware, providing makers and system integrators with a flexible way to implement embedded 3D vision solutions. Currently, Intel’s RS400™ generation presents state-of-the-art specifications in terms of resolution and operating range (Table 6.1), considering commercial mass market 3D active stereoscopy cameras. Intel propose two different vision modules, the RS410™ and the RS430™, based on the D4 processor that the they implement in two ready-to-use cameras, the D415™ and the D435™. As for the Kinect V2™ and the Orbbec Astra S™, we are investigating the metrological performances of the Intel D415™ and D435™ depth sensor. First, we present a preliminary analysis of the devices. Then, we focus our test on pixel-wise characterization along the depth, the sensor plane and the angular parameters. Last, performances for shapes reconstruction are analyzed. (Table presented).
