چکیده
Abstract -It is important to assess street-parking vehicles causing traffic problems in urban areas, however, it is performed manually and at high cost. It is a top priority for reducing cost, to develop a detection system of those vehicles. We propose a detection method using a laser-range finder and a line-scan camera. In the detection method, two kinds of cluster analysis are applied to range points: One is for clustering points at each scan, and the other for clustering points over several scans. Each cluster of range points means a vehicle. As a result of verification experiments in real roads, a detection rate reached 95 %.

Detection of Street-Parking Vehicles Using Line Scan Camera and Scanning Laser Range Sensor
Street-parking vehicles in urban areas are causing various traffic problems, however, have been counted manually in the traffic census, including counting error. We propose two auto-detection methods; one is based on an epipolar-plane image analysis, using a line-scan camera, and the other is based on three-dimensional restoration, using a scanning laser range sensor. Both methods achieve high ...
متن کاملThe algorithm to generate color point-cloud with the registration between panoramic image and laser point-cloud
Laser point cloud contains only intensity information and it is necessary for visual interpretation to obtain color information from other sensor. Cameras can provide texture, color, and other information of the corresponding object. Points with color information of corresponding pixels in digital images can be used to generate color point-cloud and is conducive to the visualization, classifica...
متن کاملContours Extraction Using Line Detection and Zernike Moment
Most of the contour detection methods suffers from some drawbacks such as noise, occlusion of objects, shifting, scaling and rotation of objects in image which they suppress the recognition accuracy. To solve the problem, this paper utilizes Zernike Moment (ZM) and Pseudo Zernike Moment (PZM) to extract object contour features in all situations such as rotation, scaling and shifting of object i...

متن کاملLaser Scanning and Its Potential to Support 3d Panoramic Recording
Today very fast terrestrial laser scanners are available which can be very well combined with panoramic cameras to make 3Dpanoramic recording possible. Due to the very precise depth information of the laser scanner and the high resolved color information provided by the CCD sensor of the panoramic camera 3D-panoramic images of high quality can be obtained. In order to assess the performance of ...
