Method and system of evaluation of source map sufficiency for vehicle map integration

A system, comprising:

• a display arranged to show horizontal input maps;
• memory to store data related to visual objects shown on the horizontal input maps to be displayed on the display;
• processor circuitry forming at least one processor communicatively coupled to the memory, and wherein the at least one processor is arranged to operate by:
• receiving map image data of multiple horizontal input maps of an overlapping geographical area and arranged to be displayed on a display device on a vehicle, wherein each map has style data and at least one layer associated with a type of geographical data shown on the map, wherein the type of geographical data provides one or more visual objects each having a geographical location and indicating information on the layer;
• generating multiple plain maps comprising removing the style data from the map image data of each input map;
• determining common layers between at least two of the plain maps showing the same type of geographical data;
• determining discrepancies between compared visual objects originally from different plan maps of common layers, wherein the compared visual objects are provided from the plain maps to indicate the same or overlapping geographical location and at least some of the same information;
• and
• generating data of a discrepancy map of the discrepancies.

A non-transitory computer-readable medium having computer-executable instructions stored thereon that, when executed by a computing device, cause the computing device to operate by:

• receiving map image data of multiple input maps of an overlapping geographical area and arranged to be displayed on a display device on a vehicle, wherein each input map has style data and at least one layer each associated with a different type of geographical data shown on the map;
• generating, by at least one processor, multiple plain maps comprising removing the style data from the map image data of each input map;
• determining, by at least one processor, common layers between at least two of the plain maps showing the same type of geographical data;
• determining, by at least one processor, data of a discrepancy map of discrepancies between the common layers of the at least two plain maps and for each common layer of the at least two plain maps;
• and
• generating, by at least one processor, an error value of the at least two plain maps comprising using the discrepancy maps.
