Abstract
A road updating method for an electronic map is provided. The method includes acquiring a target road in the electronic map, the target road being at least one of an intrinsic upper road of an overpass or an intrinsic lower road of the overpass, acquiring a target node of the target road, the target node being at least one of a first node of the target road or a last node of the target road, acquiring visible points within a preset range of the target node, determining path lengths between the visible points and the target node, determining an extended road of the target node according to the path lengths between the visible points and the target node, and updating the electronic map based on the extended road.
Claims20
A road updating method for an electronic map, performed by at least one processor, the method comprising:
- acquiring a target road in the electronic map, the target road being at least one of an intrinsic upper road of an overpass or an intrinsic lower road of the overpass;
- acquiring a target node of the target road, the target node being at least one of a first node of the target road or a last node of the target road;
- acquiring visible points within a preset range of the target node;
- determining path lengths between the visible points and the target node;
- determining an extended road of the target node according to the path lengths between the visible points and the target node;
- and
- updating the electronic map based on the extended road.
An apparatus, comprising:
- at least one memory configured to store computer program code;
- and
- at least one processor configured to access said computer program code and operate as instructed by said computer program code, said computer program code comprising:
- first acquiring code configured to cause the at least one processor to acquire a target road in an electronic map, the target road being at least one of an intrinsic upper road of an overpass or an intrinsic lower road of the overpass;
- second acquiring code configured to cause the at least one processor to acquire a target node of the target road, the target node being at least one of a first node of the target road or a last node of the target road;
- third acquiring code configured to cause the at least one processor to acquire visible points within a preset range of the target node;
- first determining code configured to cause the at least one processor to determine path lengths between the visible points and the target node;
- second determining code configured to cause the at least one processor to determine an extended road of the target node according to the path lengths between the visible points and the target node;
- and
- first updating code configured to cause the at least one processor to update the electronic map based on the extended road.
A non-transitory computer-readable storage medium storing computer instructions that, when executed by at least one processor of a device, cause the at least one processor to:
- acquire a target road in an electronic map, the target road being at least one of an intrinsic upper road of an overpass or an intrinsic lower road of the overpass;
- acquire a target node of the target road, the target node being at least one of a first node of the target road or a last node of the target road;
- acquire visible points within a preset range of the target node;
- determine path lengths between the visible points and the target node;
- determine an extended road of the target node according to the path lengths between the visible points and the target node;
- and
- update the electronic map based on the extended road.
