Real-time real-scene matching vehicle navigation method and device based on double cameras

Abstract

The invention discloses a real-time real-scene matching vehicle navigation method and a real-time real-scene matching vehicle navigation device based on double cameras. The navigation method uses the manner of combining an ordinary camera and an infrared camera based on navigation of an ordinary navigation map to capture real-time images by the ordinary camera to be displayed on the screen of a navigator, the images captured by the infrared camera are matched with the original navigation map, so that a navigation instruction on the navigation map can be mapped to the real-scene map to finish the real-scene navigation. The device comprises a patch monitor, a display drive unit module, a control storage processing unit module, a navigation information receiving antenna module, a color camera, an infrared camera, a USB output module and a power module, wherein the color camera and the infrared camera are both connected with a control processor of the navigation device. The device disclosed by the invention is simple in structure, capable of avoiding large occupied storage space for storing the real-scene map, less in computation amount, fast in response and low in cost.

Description

technical field [0001] The invention belongs to the technical field of vehicle navigation, and in particular relates to a method and device for real-time scene matching vehicle navigation based on dual cameras. Background technique [0002] Existing portable car navigation devices generally navigate through simplified map models. The map model in the navigator is usually a series of simplification and trimming of the real map from the top view angle, only the main road and important buildings are kept, and the details of the roadside are ignored, so that the amount of information on the map can be greatly reduced, which is convenient for the navigator. Store and ensure the timeliness of display. During the navigation process, the current position is determined by GPS global positioning, and the destination is input by the user, and then the corresponding location is searched on the map. Then calculate the path from the current position to the destination according to the r...
