Laser Based Real-Time Measurement of Thorax 3D Deformation with Motion Compensation

We present a novel method for full-area, 3D visual breathing assistance with body motion compensation. The method is based on Kinect structured light triangulation sensor and uses local features detection algorithm to correct the undesired body motion during breathing training. The measuring system is contactless and operates in real-time with 30 frames per second. The feature detection algorit...

Robust real-time tracking combining 3D shape, color, and motion

Real-time tracking algorithms often suffer from low accuracy and poor robustness when confronted with difficult, real-world data. We present a tracker that combines 3D shape, color (when available), and motion cues to accurately track moving objects in real-time. Our tracker allocates computational effort based on the shape of the posterior distribution. Starting with a coarse approximation to ...

Flexible real-time natural 2D color and 3D shape measurement.

The majority of existing real-time 3D shape measurement systems only generate non-nature texture (i.e., having illumination other than ambient lights) that induces shadow related issues. This paper presents a method that can simultaneously capture natural 2D color texture and 3D shape in real time. Specifically, we use an infrared fringe projection system to acquire 3D shapes, and a secondary c...

Sensor-based Real-time Error Compensation

Machining accuracy can be greatly increased through the use of highresolution position sensors, calibration of machine tool or robot components, and other measures which serve to improve the machine’s positional response to part programs. Unfortunately, much of the inaccuracy in finished parts is due to dynamically varying quantities, such as tool wear, chatter, or thermal expansion; random err...

Real-time 3D Motion Capture

We describe a real-time 3D computer vision system for detecting and tracking human movement and providing a person with control over the movement of a virtual puppet. Multiple cameras observe a person; silhouette analysis and template matching achieve real-time 3D estimation of human posture. A dynamics/kinematics model of human body and Kalman filter are utilized to help the tracking process a...
