Asus, PrimeSense Reveals Motion Sensing for PC

It's a Kinect-like device for the PC, however it's by ASUS and called WAVI Xtion.

Both ASUS and PrimeSense announced a joint project that will bring motion sensing controls to the PC, thus possibly debunking any rumors that Microsoft will eventually bring Windows-based support for the Xbox 360's Kinect motion sensing device.

According to both companies, the WAVI Xtion for the PC will utilize PrimeSense's core 3D sensing solution already licensed by Microsoft for Kinect. The difference will be that the PC-oriented device will be developed primarily for browsing multimedia content, accessing Web sites and social networks when the PC is hooked up to the living room TV.

ZCam

ZCam is a brand of time-of-flight camera products for video applications by Israeli developer 3DV Systems. The ZCam supplements full-color video camera imaging with real-time range imaginginformation, allowing for the capture of video in 3D.

The original ZCam, released in 2000, was an ENG video camera add-on used for digital video compositing. Before agreeing in March 2009 to sell its assets to Microsoft, 3DV had planned to release a ranging video webcam (previously called the Z-Sense), also under the name ZCam. The ZCam webcam was one of several competing real-time range imaging camera products in development that target home game controller applications.

Technology.

The ZCam's time-of-flight camera system features a near-infrared (NIR) pulse illumination component, as well as an image sensor with a fast gating mechanism. Based on the known speed of light, ZCam coordinates the timing of NIR pulse wave emissions from the illuminator with the gating of the image sensor, so that the signal reflected from within a desired depth range is captured exclusively. The amount of pulse signal collected for each pixel corresponds to where within the depth range the pulse was reflected from, and can thus be used to calculate the distance to a corresponding point on the captured subject.

OpenCV Camera Calibration

Camera calibration is important for any image processing to be a highly accurate representation of the real world. "Geometric entities of the camera, such as the projection centre and image plane, can be computed quite simply from its matrix representation. Specializations of the general projective camera inherit its properties, for example their geometry is computed using the same algebraic expressions."

This algorithm show how to extract the relevant camera parameters from a sequence of images with using of OpenCV library. For this example you will need to print out this image as a full page:

3D CV-t debuger :)

We are in the process of developing application for testing implementations of recognition methods

The development plan:
1) Implement the ability to view video in 3D scene. [done]
2) The free movement in a 3d scene. [done]
3) The process of video playback [done]
4) User can load functions (software modules) for detection (which are used for video playback). [in process]

KinectFusion: Real-Time Dense Surface Mapping and Tracking

Kinect is a motion sensing input device by Microsoft for the Xbox 360 video game console. Based around a webcam-style add-on peripheral for the Xbox 360 console, it enables users to control and interact with the Xbox 360 without the need to touch a game controller, through a natural user interface using gestures and spoken commands.

Microsoft KinectFusion software provides real-time to recover 3D scene based on data from the Kinect to perform segmentation and tracking of objects.

Searching pairs of identical key points

The problem of searching pairs of identical key points on two images has been solved with using of algorithm that performs a simple search and comparison of elements of descriptors arrays.

The same problem has been realized with using of FLANN library in OpenCV.
