3.检测模型启动
3.1模型的单独测试
//模型的单独测试
//pointpillars detect test
./bazel-bin/modules/perception/lidar/lib/detector/point_pillars_detection/point_pillars_test
//cnn seg test
./bazel-bin/modules/perception/lidar/lib/detector/cnn_segmentation/cnn_segmentation_test
3.2检测模型的配置
//更换检测模型配置文件
modules/perception/production/data/perception/lidar/models/lidar_obstacle_pipeline/velodyne16/lidar_obstacle_detection.conf
主要的模型：PointPillarsDetection，CNNSegmentation，NCutSegmentation
