Embodiment 1
[0076] like figure 1 As shown, the present invention provides a method for updating the map boundary of an open-pit mine loading area, the method is executed by a computer, and the method includes:
[0077] S1. Obtain map vector data and current operation scene;
[0078] S2. Based on the current operation scenario, update the map boundary, specifically including:
[0079] S201. When the current operation scene is a multi-step operation scene, update the step map boundary where the excavator and the unmanned vehicle are located;
[0080] S202. When the current operation scenario is a non-multi-step operation scenario, only update the step map boundary where the unmanned vehicle is located.
[0081] The beneficial effects of this embodiment are:
[0082] ①According to the actual situation of the open-pit mine loading area, different map update methods can be adopted according to different operation scenarios. Compared with the existing ones that can only be updated for non-mu...
Embodiment 2
[0141] The present invention also provides a map boundary update system for the loading area of an open-pit mine, the system includes a memory, a processor, and a computer program stored in the memory and operable on the processor, and the processor executes the computer program When implementing the steps of the above method.
[0142] It can be understood that the map boundary update system of the loading area of the open-pit mine provided by the embodiment of the present invention corresponds to the above-mentioned method for updating the map boundary of the loading area of the open-pit mine. The corresponding content in the method for updating the map boundary of the loading area will not be repeated here.
Embodiment 3
[0144] The present invention also provides a storage medium on which a computer program is stored, and when the computer program is executed by a processor, the above method is realized.
[0145] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0146] ②According to the actual situation of the open-pit mine loading area, different map update methods can be adopted according to different operation scenarios. Compared with the existing ones that can only be updated for non-multi-step operation scenarios, the intelligent level of the mine can be improved.
[0147] ②Based on the adjacent map boundary step_udpate_boundary, the map boundary of the step where the excavator is located is detected point by point and updated by offset. On the premise of ensuring that the map boundary change area is updated in time, it also makes the step where the unmanned vehicle is located and the excavator. The local boundary geometry of the steps ...

Abstract
The invention provides a map boundary updating method and system for an open-pit mine loading area, and relates to the technical field of intelligent mine fields. Different map updating methods can beadopted according to different operation scenes in allusion to the actual situation of the open-pit mine loading area, and compared with the existing method that updating can only be carried out fornon-multi-step operation scenes, the intelligent level of a mine field is improved. According to the method, point-by-point detection is carried out on the map boundary of the step where the excavatoris located on the basis of the adjacent map boundary step, updating is carried out through offset, and on the premise that it is guaranteed that the map boundary change area is updated in time, the geometrical shape of the local boundary of the step where the unmanned vehicle is located tends to be consistent with the geometrical shape of the local boundary of the step where the excavator is located. Meanwhile, based on the horizontal distance difference and the height difference as detection indexes, the method conforms to the scene of on-site actual operation, the algorithm complexity is very low, the detection efficiency is very high, and the overall intelligent level is further improved.
Description
technical field [0001] The invention relates to the technical field of smart mines, in particular to a method and system for updating map boundaries of an open-pit mine loading area. Background technique [0002] The unmanned transportation solution for open-pit mines is the process of loading soil and rocks in the loading area by unmanned vehicles according to the mine operation plan, and transporting them to the dump site for dumping; due to the complex terrain of the loading area, the same loading consists of different steps. Excavators and unmanned vehicles can operate on different steps at the same time, and the accuracy of updating the boundaries of the high-precision map loading area is a key indicator for unmanned vehicle loading operations. [0003] Existing methods are only aimed at the scene where the excavator loads the unmanned vehicle outside the map boundary, and only need to update the map boundary where the current step is located according to the scene oper...
