Embodiment Construction

[0049] The automatic map building and automatic map update system of the present invention is made up of software and hardware:

[0050] software such as figure 1 As shown, it consists of five parts: on-board data acquisition unit, data transmission unit, data storage unit, calculation unit and vector map drawing unit, among which:

[0051] The vehicle-mounted data acquisition unit is deployed on the mapping data acquisition vehicle. The function of the vehicle-mounted data acquisition unit is to collect lidar point cloud frames, collect vehicle speed data, collect IMU direction angle (Yaw) data, and collect GPS (consumer-grade GPS, meter level precision) data, and collect the acceleration and angular velocity data of the IMU.

[0052] The data transmission unit is deployed on the mapping data acquisition vehicle and the mapping server at the same time. The data transmission unit has three functions. The first function is to transmit the data collected by the vehicle data acq...

Abstract

The present invention provides an automatic map building and automatic map update system for port unmanned logistics vehicles, including software and hardware, and the software includes a vehicle-mounted data acquisition unit, a data transmission unit, a data storage unit, a calculation unit and a vector map drawing unit, The hardware includes lidar, GPS, IMU, vehicle networking module and mapping server. The port prior map is automatically updated through timing or manual triggering, which solves the problem of unmanned vehicle positioning failure caused by slow changes in the environment of the port unloading area.

Description

technical field [0001] The invention relates to the technical field of automatic driving and map data processing, in particular to an automatic map building and automatic map update system for port unmanned logistics vehicles. Background technique [0002] With the maturity of unmanned driving technology, unmanned driving technology is the first to land in closed unmanned scenes such as logistics parks and container port unloading areas. [0003] In the closed scene of the port unloading area, due to the incomplete lane lines and the lack of lane lines in some driving areas, traditional automatic driving solutions that rely on lane line recognition and lane line maintenance cannot complete the task. The current mainstream port driverless solution is to control the vehicle to move to the destination by calculating the accelerator opening and steering wheel angle based on the vehicle's current accurate position and desired destination. At present, there are two main ways for ...
