Currently, there is a great interest in the study of three-dimensional reconstruction from digital images. The applications of photogrammetric algorithms has allowed us significant improvements in procedures of camera calibration, movement of objects in scenes, shape from shading and range images. The procedure of the distance estimation from simple images is important to find the depth measure...

Virginia Tech is currently developing a new autonomous vehicle as a research platform. This vehicle is being used to investigate techniques in autonomous landmine/UXO detection. In addition, it was entered in the 2000 Intelligent Ground Vehicle Competition. This vehicle senses its surroundings using two (non-stereo) color CCD cameras, a SICK laser range finder, and wheel encoders. The cameras g...

The automated inspection is desired to detect the vehicle in large parking space, which is difficult to survey by fixed the vision-sensor. We purposed mobile robot surveillance in parking space for parking lot inspection. To obtain the parking lot information, vision sensor is wide useful for parking lot state checking which measurement is difficult to obtain the positioning of vehicle while ac...

This paper presents a system for object digitalization by use of a laser stripe triangulation displacement sensor and an industrial MOTOMAN robot. In order to ensure the precision of the scanning system, a novel calibration scheme referred to as one-stage approach is proposed. This procedure mainly utilizes a circular-marked board as calibration target and calibrates the range finder and hand-s...

This paper describes a method of robustly modeling road boundaries on-line for autonomous navigation. Since sensory evidence for road boundaries might change from place to place, we cannot depend on a single cue but have to use multiple sensory features. It is also necessary to cope with various road shapes and road type changes. These requirements are naturallymet in theproposedparticle filter...
