Abstract: The present application relates to the technical field of intelligent transportation, electronic map, and positioning and navigation and, in particular, to a navigation map evaluation method and apparatus, a device and a readable storage medium. The electronic device acquires a travelling simulation video of the road section to be tested and a real environment image of each location point on the road section to be tested, generates a linkage video according to the navigation simulation image and the real environment image of each location point on the road section to be tested, and evaluates a first map according to the linkage video. In the process, the navigation map is evaluated through a way of simulation, which achieves the purpose of reducing the cost of manpower and material resources in the process of the navigation map evaluation.
