With the development of technology and the reduction of cost, the field of robot, unmanned aerial vehicle and unmanned driving has become an important application field of LiDAR in the field of laser radar. There are many kinds of sensors in the field of robotics, including cameras, lidar, millimeter-wave radar, ultrasound, infrared and many other sensors. The features and advantages of each sensor are not

with many different types of main sensors. Each type of sensor has different advantages and disadvantages, so the sensor data from different sensors should be effectively fused. The sensors commonly used in unmanned driving are now available in the following categories. (1) Gps/imu: The Gps/imu sensing system helps unmanned vehicles to self-locate by using global positioning and inertia update data up to the Hz frequency. GPS is a relatively accurate positioning sensor, but its update frequency

The Kitti contains real-world image data captured in urban, rural and expressway scenes, with up to 15 cars and 30 pedestrians in each image, as well as various levels of occlusion and truncation. The entire data set consists of 389 pairs of stereoscopic images and optical flow graphs, 39.2 km visual ranging sequences and images of over 200k 3D labeled objects [1], sampled and synchronized at 10Hz frequencies. Overall, the original datasets were classified as ' Road ', ' Ci

ObjectiveThe Point Cloud Library (PCL) is a powerful, open-source C + + library that will help us greatly in the field of LIDAR data processing if a good PCL can be used. LiDAR technology after several decades of development, at home and abroad on the LiDAR point cloud data processing has been very rich, but there are still hardware development speed is greater t
