Abstract |
In recent years, the technology advances very fast. The research of advanced vehicle control and safety system (AVCSS) becomes more critical in the world. AVCSS includes sensor, computer, communication and control technologies applied on the vehicle for assisting driving safety. The core technology consists of a vehicle anti-collision system, automatic driving, and automatic parking. However, these technologies must have the image information in front of vehicle. The machine vision can be divided into monocular vision and binocular stereo vision. The environmental information provided by monocular visual images may not be sufficient for the safety requirements upgrade. Besides, the binocular stereo vision can get more ambient information. By stereo vision algorithms, the system can calculate the depth image information to infer depth map information. The image matching algorithm is also important in stereo vision. Therefore, this thesis proposes an obstacle recognition system based on semi-gobal matching algorithm (SGBM) which used fuzzy theory to select a threshold to achieve better recognition results. |
