解决方案

在costmap_common_params.yaml文件添加一行inf_is_valid: true，结果无效

scan:
    data_type: LaserScan
    topic: /scan
    sensor_fram: base_link
    marking: true
    clearing: true
    min_obstacle_height: -0.5
    max_obstacle_height: 0.5
    inf_is_valid: true  # 添加此行

将min_obstacle_height: -0.5更改为min_obstacle_height: 0，成功解决
