【 摘 要 】

The fuzzy model based on the centreline ultrasound signal is pro-posed to solve the poor orientation of ultrasonic sensors in the environment modelling in this paper. The locations of ultrasonic arc feature points were extracted and distinguished. For the problem of poor resolution of split type ultrasonic sensors, fuzzy algorithm is applied to identify the obstacle such as line, corner, or arc structure. Ultrasound environment map based on fuzzy is constructed and the maximum distance and angle deviation is 1.2cm and 3°, showing that the accuracy of obstacle classification based on ultrasound and Fuzzy is improved.
