Algorithmic Improvement for CMVision in Omnidirectional Image Processing
LU Li-xiu · Jisuanji fangzhen · 2008
In light of the characteristic that the omnidirectional image has too many invalid pixels,this paper improves the performance of arithmetic prominently through avoiding processing these invalid pixels,at the same time,avoiding some confusions of color recognition.In view of the characteristic that the omnidirectional image is centrosymmetric,the paper improves the information data structure of regions to make it describe the position of objects more reasonably and exactly,and extract these information from the image efficiently through table-search technology,which paves the way for the robot's path planning and obstacle avoidance.The experiment based on CMVision library proves that the improved library executes more efficiently and obtains more exact object information compared with old version in omnidirectional image processing.
