Recently, many types of omni-directional cameras have been developed and attracted much attention in a number of different fields. Especially, the multi-camera type of omni-directional camera has advantages of high-resolution and almost uniform resolution for any direction of view. In this paper, an extrinsic camera parameter recovery method for a moving omni-directional multi-camera system (OM...
TCP optimization in mobile ad hoc networks MANETs is a challenging issue because of some unique characteristics of MANETs. Packet losses in MANETs are mainly due to congestion and frequent link failures but in case of wired networks packet losses are mainly due to congestion. To optimize TCP in MANETs we use congestion control and avoidance algorithms. In this paper, we describe an NS2based sim...
A collective transport strategy, inspired by the food retrieval procedure of ant colonies, has been implemented on a swarm of robots that are smaller than the object. A simple odometry-based team coordination strategy in combination with an omni-directional camera has been implemented, resulting in a well-coordinated effort by the robots without using any communication. The strategy is fully de...
Mobile communications demands present new challenges for transmission. Traditionally, antennas used at base stations to communicate with mobile units within an area are omni-directional. In order to allow a higher density of participants within the area, a “pencil” beam is used. The beam tracks and follows the movement of the mobile unit. This results in an additional advantage: the fading effe...
With a panoramic view of the scene, a single omnidirectional camera can monitor the interior and exterior of the vehicle simultaneously. Omni-directional cameras have been shown to produce useful data for determining head gaze orientation from within a vehicle. We examine the issues involved in integrating lane-tracking functions using the same omni-directional camera. We present analysis on th...
Improved ranging accuracy is obtained by the development of a novel ultrasonic sensor ranging algorithm, unlike the conventional ranging algorithm, which considers the divergence angle and the incidence angle of the ultrasonic sensor synchronously. An ultrasonic sensor scanning method is developed based on this algorithm for the recognition of an inclined plate and to obtain the localization of...
