This paper proposes a new design for in-door autonomous artificial landmark, named IR Coding. The main objective of using this design is to offer auto-calibration for mobile robot, and reduce the computational and hardware cost. Also, the design does not require any start-up configurations. Moreover, a numerical sequence can be obtained from the IR coding directly rather than computing it by the robot...
Cardiovascular disease affects millions of Americans each year. Interventional guidance systems are being developed as treatment options for some of the more delicate procedures, including targeted stem cell therapy. As advanced systems for such types of interventional guidance are being developed, electromagnetic (EM) tracking is coming in demand to perform navigation. To use this EM tracking technology,...
Navigated ultrasound (US) imaging is used for the intra-operative acquisition of 3D image data during image-guided surgery. The presented approach includes the design of a compact and easy to use US calibration device and its integration into a software application for navigated liver surgery. User interaction during the calibration process is minimized through automatic detection of the calibration...
To detect menology environments, we present an environmental perception technology based on binocular stereo vision system. The binocular vision system is calibrated by Zhangzhengyou calibration method, and the original images are rectificated by epipolar rectification. Based on the revised binocular vision system, rectificated images are preprocessed by adopting histogram equalization, maximal between-cluster...
In this article we present a novel navigation approach for an autonomous robot in an unknown maze based on calibration-free visual information. On one hand, we segment images to obtain the approximate traversable region and on the other hand the lines and corners in images are also extracted to help a robot understanding the topological structure. In the experiment, our navigation approach running...
