Robot localization is one of the hottest research spots. Many scholars have studied the landmark localization which is cheap, stable, and simple in the indoor environment. This paper presents a low-cost localization system based on the artificial landmarks with two degree of freedom platform camera. The landmarks are put on the ceiling in order to decrease the interference. A 2-DOF pan-tilt has been...
Moving object detection with moving camera is a difficult and hot issue. In order to detect moving object effectively and rapidly, this paper proposes a moving object detection algorithm by flow vector classification and multi-view geometric constraints. First, corner feature points with large eigenvalue are searched, and the feature points of present frame is matched with the previous one to compute...
We propose a BEST (Background subtraction and Enhanced camShift Tracking) method for a scout robot tracking a moving object in real time. A modified back subtraction method based on time axis is used to segment the moving object in a complicated environment. The centroid and area are chosen as the feature to judge target. We proposed a novel method that combines Camshift, AWS (Adaptive Window Selecting...
A camera can assist a robot to detect and track objects when it is used in a scout robot system, and hence, help the robot to navigate. This paper discusses problems of tracking a human face where an active camera is installed on a 2 DOF pan and tilt. Kinematics model between object in motion and image of camera is built. The face detection and tracking algorithm is introduced which uses complexion...
