Questions tagged [realsense]

Intel® RealSense Technology is a suite of depth and tracking technologies designed to give machines and devices depth perceptions capabilities that will enable them to "see" and understand the world.

RealSense consists of series of consumer grade 3D cameras together with an easy to use machine perception library that simplifies supporting the cameras for third-party software developers.

The project can be considered a successor to Microsoft Kinect camera, which aims to find uses for the technologies pioneered there in the consumer market in applications beyond gaming, something which Kinect struggled with.

How to check for substantial change in two depth frames?

My goal is to detect any change in frames(single channel. each pixel is depth value). On app init, I take average of all corresponding pixels of first 30 frames so one average background frame will be created. On new frames arrival I subtract each…
