Abstract
A method, a system, and a computer program product for calibrating a depth sensor of a device. The method includes simultaneously capturing within a current scene: a red-green-blue (RGB) image by a RGB sensor of a device; and an infrared (IR) image by an IR sensor of the device. The method further includes concurrently capturing, via an IR sensor of the device, an uncalibrated depth image within the current scene. The method further includes calculating calibration data from the RGB image and the IR image and applying the calibration data to the uncalibrated depth image to generate a corrected depth image. The method further includes combining the RGB image and the corrected depth image to generate a RGB depth image. The method further includes, presenting the RGB depth image on an output device.
