A window-type warning system for vehicles is proposed. Auxiliary information is directly displayed on the windshield of a vehicle. According to the image information of obstacles and the driver from cameras, the coordinates of the obstacles relative to the moving vehicle are calculated in realtime. The line of vision equation is constructed from coordinates of the driver and an obstacle. The explicit...
In recent years, the weighted average algorithm is discussed more and more. In order to maximize the Signal Noise Ratio (SNR) and minimize the variance of the signals, the weights are utilized. In this thesis, a traffic velocity detection of adaptive weighted-average is presented, in which, a reasonable result with enough precision could be got. Compared with other weighted average method, a large...
Tracking reentry vehicle with strong maneuvers on-line is a challenging task. The key is to develop suitable dynamic models and estimation methods. Two kinds of modeling methods are discussed for reentry tracking, and the unscented filter (UKF) is introduced to the nonlinear tracking system. To reduce the computational load, three simplifications of UKF are developed. Furthermore, the feasibility...
