Description

technical field [0001] The invention relates to an unmanned driving application system and an application method thereof. Background technique [0002] At present, almost all unmanned cars nowadays use ground-mounted sensors to realize unmanned driving functions based on navigation of global satellite positioning sensors, millimeter-wave radars, and laser ranging sensors. However, the sensor on the ground vehicle is limited by the height, and the interference data of many factors in the measurement is inaccurate, and at the same time, it is more limited in the aspect of overtaking. However, global satellite positioning sensor data is surface data rather than path data, and there are errors in using global satellite positioning sensor data alone. [0003] At the same time, when planning the operation of unmanned driving equipment, it is usually necessary to collect a large number of sampling points, and then generate a large number of possible alternative paths based on the ...

AI Technical Summary

Problems solved by technology

Since a large number of candidate paths need to be generated, smoothing processing is required when generating candidate paths, and a large amount of computing resources are also consumed when selecting the best target path from a large number of candidate paths

Therefore, the operation planning process is complex and consumes a lot of computing resources

As a result, the efficiency of operation planning is reduced, the complexity of operation planning is increased, and the accuracy of operation planning is also low.

[0004] In addition, the Chinese patent with the publication number CN101387522A discloses an electromagnetic tracking method based on inductive coils. Although the control and navigation algorithm is simple and the cost is low, the navigation accuracy is affected by the number and layout of the inductive coils, and the volume is large and inconvenient to use. Deployed in conventional vehicles, and the number and layout of coils need to be redesigned for different environments, which is too cumbersome

[0005] Furthermore, the Chinese patent whose publication number is CN103048996A discloses an automatic guided vehicle, a system and a navigation method based on a laser scanning range finder. Although the laser scanning environment is used to construct a map and then navigate, compared to the traditional laser navigation method based on reflectors, Its environmental requirements are further reduced; however, its positioning accuracy is heavily dependent on the encoding angle, gyroscope, laser head and algorithm, and requires more than two laser heads, resulting in more complex navigation and control algorithms and higher overall cost

[0006] The Chinese patent with the publication number CN103777637A discloses a non-reflective laser autonomous navigation vehicle and its navigation method. It uses a single laser scanning environment to construct a map for navigation. Compared with the traditional reflector-based laser navigation method and multi-laser navigation, Its requirements on the site environment and algorithms are further reduced, but its path planning is heavily dependent on motor encoders and gyroscopes, and the calculation amount of this navigation method is too large, and the complexity of navigation and control algorithms is too high, resulting in the same overall cost. high
