Depth sensing system and method thereof

Abstract

A depth sensing system includes a light-emitting device, a sensing module and a controller. The light-emitting device is configured to emit a light beam toward to a scene. The sensing module is configured to receive a reflective beam reflected from the scene to generate a scene image. The controller is electrically connected to the light-emitting device and the sensing module. The controller is configured to calculate an IQ image of the scene according to the scene image. The controller is configured to calculate confidence values of each pixel of the IQ image to generate a confidence image. The controller is configured to calculate a calibrated IQ image according to the confidence values, and then calculate a depth image of the scene. A depth sensing method is also provided.
