代码解析之range_sensor_layer中costmap更新的方法和模型(一) 在ROS Navigation中,costmap_2d定义了代价地图,range_sensor_layer根据传感器探测结果更新之。这里的传感器主要指的是超声波/红外测距传感器,共同特征是探测范围是一个扇形区域,而不是像激光雷达一样是一条线。所以,给定一个距离返回值,我们并不能确定具体是扇形的弧边沿的哪个栅格才是障碍物,弧上任一点都有可能,需要对该扇形区域内的栅格占用概率建模。

     建模的理论请参考文献《一种基于概率的超声波模型的设计》(刘利枚)和《a comparison of three uncertainty calculi for building sonar-based occupancy grids》。
