Abstract
Due to the influence of factors such as Angle,direction and distance between the scanning area and the camera point,the laser can cover a limited area,which affects the accuracy of online detection of the passable area.Therefore,an airborne liDAR online detection method of passable area based on fan-block threshold determination is studied.The fan-block area of airborne lidar is determined by the fan-block threshold including the maximum scanning distance threshold and the distortion coefficient threshold.The fan-block area data is processed by the maximum entropy prediction model and the adjustment coefficient,and the online detection of the passable area of airborne lidar is realized by combining the wavelet transform.The experimental results show that the proposed method can detect changes in the road width information at detection points 4,6 and 7,and can effectively detect obstacles in the area,thus improving the detection accuracy of the passable area and achieving a good detection effect.关键词
