Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific embodiments.

[0019] The unmanned vehicle parking safety monitoring system based on lidar includes vehicle lidar, point cloud data processing module based on point cloud library, laser ranging module and control switch module. The system uses lidar to scan the road condition data near the vehicle in real time, and the scanned data is transmitted to the computing unit. The distance module calculates the distance and speed of each object, judges whether it harms the passengers to get off, and controls the door opening and closing through the control unit to realize the safe getting off of the passengers.

[0020] When the automatic navigation of the vehicle ends, the lidar continues to scan the road conditions around the vehicle and obtain point cloud data.

[0021] The point cloud data processing program in the computing unit is based on PCL (point cloud library), which first extracts th...

Abstract

The present invention discloses an unmanned vehicle parking safety monitoring system based on a laser radar, belonging to the technical field of unmanned vehicles. The laser radar is used to scan traffic data near a vehicle in real time, the scanned data is transmitted to a calculation unit, a point cloud data processing program in the calculation unit divides, clusters, reconstructs and identifies the point cloud data obtained by scanning, then a laser ranging module calculates the distance and speed of each object, whether the object endangers the passengers who get off the vehicle is judged, the opening and closing of a vehicle door are controlled through a control unit, and a purpose that the passengers safely get off the vehicle is achieved. According to the system, the laser radar installed in the unmanned vehicle is used to scan the traffic data near the vehicle in real time, the distance and speed of each object are calculated through the laser ranging module, whether the object endangers the passengers who get off the vehicle is judged, the opening and closing of the vehicle door are controlled through the control unit, and the safety of the passenger is ensured.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicles, in particular to an unmanned vehicle parking safety monitoring system based on laser radar. Background technique [0002] With the development of driverless technology, driverless cars will gradually realize civilian use. At present, unmanned driving technology mainly obtains high-precision maps around the vehicle through lidar, combines GPS global positioning system and IMU inertial navigation module to perceive the characteristics of the environment in real time, performs map matching and positioning, analyzes the planned path, and controls the vehicle through the vehicle CAN bus. The lidar scans the surrounding environment 360 degrees using the rotational scanning method. This scanning method can directly obtain point cloud data, which includes the three-dimensional spatial position coordinate information, color (RGB) information and intensity (Intensity) information of the target. ...
