Is Kinect a depth camera?

Is Kinect a depth camera?

Our experiments enable us to directly compare the results for the two devices. We evaluate and characterize in this paper the Microsoft Kinect v1 and Kinect v2, which are RGB-D cameras consisting of one depth and one color camera. The depth image records in each pixel the distance from the camera to a seen object. Fig.

How does the Kinect sensor depth?

The depth sensor contains a monochrome CMOS sensor and infrared projector that help create the 3D imagery throughout the room. It also measures the distance of each point of the player’s body by transmitting invisible near-infrared light and measuring its “time of flight” after it reflects off the objects.

What is RGB depth camera?

RGB-D Sensors are a specific type of depth-sensing devices that work in association with a RGB (red, green and blue color) sensor camera. They are able to augment the conventional image with depth information (related with the distance to the sensor) in a per-pixel basis.

Is Kinect a stereo camera?

Although the Xbox Kinect sensor is also able to create a depth map of an image, it uses an infrared camera for this purpose, and does not use the dual-camera technique. Other approaches to stereoscopic sensing include time of flight sensors and ultrasound.

What is inside a Kinect?

The Kinect sensor bar contains two cameras, a special infrared light source, and four microphones. It also contains a stack of signal processing hardware that is able to make sense of all the data that the cameras, infrared light, and microphones can generate.

What is RGB-D Slam?

RGBDSLAM allows to quickly acquire colored 3D models of objects and indoor scenes with a hand-held Kinect-style camera. It provides a SLAM front-end based on visual features s.a. SURF or SIFT to match pairs of acquired images, and uses RANSAC to robustly estimate the 3D transformation between them.

What is difference between depth camera and lidar?

Lidar: Measure the time a small light on the surface takes to return to its source. Depth Camera: Measure the intensity of the ambient light through the illumination of the target object. Uses Time-of-Flight remote sensing to measure the reflected light which comes from its own light-source emitter.
