Automatic assignment method, device, electronic map intelligent production system and navigation equipment

Abstract

The invention discloses an automatic value assignment method and device for line speed limit, an electronic map intelligent production system and navigation equipment. The method includes acquiring the point speed limit value in the road and the point speed limit direction corresponding to the point speed limit value; based on the preset automatic tracking principle, determining the initial road line and tracking direction to be assigned, planning the tracking path and determining The end road line to be assigned; determine the direction of the line speed limit assignment of the tracked road line according to the dashed direction of the tracked road line and the point speed limit direction corresponding to the point speed limit value, and according to the point limit The speed value and the direction of the line speed limit assignment of the tracked road line automatically perform line speed limit assignment processing on the tracked road line. The invention can make the maintenance of line speed limit free from heavy manual operation, complete the assignment of line speed limit by automatically tracking each road line, and can batch process a section of road, avoiding the defect of line speed limit maintenance one by one.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to an automatic value assignment method and device for line speed limit, an electronic map intelligent production system and navigation equipment. Background technique [0002] The line speed limit in the electronic map is manually processed according to the collected point speed limit. figure 1 It shows the process of processing line speed limit, which further includes: [0003] Step 105, judge the road line / section of road that needs to maintain the line speed limit according to the point speed limit; [0004] When collecting data based on the electronic map, the complete road is divided into several road lines (links) / sections of roads (a section of road can be one road line, or several sequentially connected road lines). When maintaining the line speed limit of the road line, set the line speed limit of the road line according to the point speed limit of the road line according ...

Problems solved by technology

In fact, the definition of the starting point and end point of the road line direction is the characteristic of the data itself. The traffic direction of the road is the expression of the real direction in the real world. When performing line speed limit maintenance, operators need to combine the real road traffic direction and data The combination of abstract expressions in the middle direction is difficult for operators to accept and understand, which affects operation efficiency and data quality
