And q2, determining the position characteristic of each three-dimensional space coordinate point in the target three-dimensional space coordinate points according to the screening driving distance corresponding to each navigation content in the target end point position information and the mapping relation between each three-dimensional space coordinate point, wherein the position characteristic is used for representing the position of the three-dimensional space coordinate point in the driving track to be divided.
And q3, dividing the target end point position information into a plurality of driving tracks according to the position indicated by the position information of each three-dimensional space coordinate point in the target end point position information.
It can be understood that when the technical solutions of the above-mentioned descriptions of step q 1-step q3 are executed, the accuracy of the plurality of driving tracks is improved by accurately determining the screening driving distance corresponding to the three-dimensional space coordinate point.
In an alternative embodiment, the inventor finds that, for each three-dimensional spatial coordinate point in the target end point position information, there is a problem that the division manner is inaccurate, so that it is difficult to accurately determine the screening travel distance corresponding to the three-dimensional spatial coordinate point, and in order to improve the above technical problem, the step of determining the screening travel distance corresponding to the three-dimensional spatial coordinate point for each three-dimensional spatial coordinate point in the target end point position information described in step q1 may specifically include the technical solutions described in the following steps q11 and q 12.

And r3, if the same driving distance exists in the screening driving distance corresponding to each interest route of the three-dimensional space coordinate point, determining that the three-dimensional space coordinate point belongs to the driving track standard.
It can be understood that, when the technical solutions described in the above steps r 1-r 3 are performed, for each three-dimensional space coordinate point in the target destination position information, according to whether the filtered travel distance corresponding to each interested route of the three-dimensional space coordinate point is the same and the filtered travel distance corresponding to each sub-navigation content of the three-dimensional space coordinate point is the same, the problem that multiple judgment branches cause inaccurate judgment is improved, so that the position characteristics of the three-dimensional space coordinate point can be accurately determined.
