Adaptive Fusion of Inertial Navigation System and Tracking Radar Data

Against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive Kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (INS/Radar). This filter involves the concept of residual-based adaptive estimation and adaptive fading Kalman filter and tunes dynamically the fil...

Multisensor robot navigation system

Almost all robot navigation systems work indoors. Outdoor robot navigation systems offer the potential for new application areas. The biggest single obstacle to building effective robot navigation systems is the lack of accurate wide-area sensors for trackers that report the locations and orientations of objects in an environment. Active (sensoremitter) tracking technologies require powered-dev...

Vehicle Navigation System

The paper proposes a vehicle flux estimator, based on Received Signal Strength Indicator measurements in order to prevent the road traffic congestions. Successive RSSI intensity determinations and the corresponding time values were used to estimate the vehicle flux in various conditions. A hierarchical network model, including a simulation module and experimental data, was implemented. In order...

Vision based navigation system

A vision based navigation system to guide an endoscope inside a human colon has been designed and tested. It uses low level vision techniques to extract two types of navigational landmarks, dark regions and curved contours. Dark regions correspond to the distant inner space of the colon, called the lumen. The curved contours represent occlusions due to the inner colon muscles. A hierarchical se...
