Chapter 17 Detecting Object Edges by Xtion Pro and Open Sources

摘要

Kinect is a popular device used in many applications such as interactive PC games, robot, virtual reality, and 3D sensing. Especially in 3D sensing, many researchers and engineers utilized Kinect-based devices to develop cheap 3D scanners. 3D scanners usually provide a better and quicker way to support the needs of 3D printing industry. This advantage is really helpful to speed up the development of 3D printing industry. Regarding this fact, this chapter attempts to propose an approach to track object edges. The approach is capable of detecting edges of a given object by Xtion pro. Many existed edge detection methods have been developed based on color information. However, this approach relies on spatial information-depth to detect object edges. The approach had also been developed successfully by open sources like OpenNI, OpenCV, and Point Cloud Library. Developing a cheap 3D scanner for 3D printing market becomes possible.
