Navigation device combining driving video record and navigation information

Abstract

The invention discloses a navigation device combining the driving video record and navigation information. The navigation device comprises a display, a recording media, a driving recorder, a GPS (global positioning system) and a processing unit, wherein the driving recorder comprises a photographic lens for shooting the live-action video of the driving road condition; the GPS receives a GPS signal; the processing unit calculates the current position according to the GPS signal, and generates the navigation information comprising a navigation path according to a destination position; and the processing unit receives the live-action video of the road condition shot by the driving recorder, finds a virtual depth-of-field reference point of the live-action video of the road condition, obtains an elevation and a picture zooming scale of the live-action video of the road condition according to the virtual depth-of-field reference point, adjusts the proportion of the navigation path according to the elevation and the picture zooming scale, draws the navigation path to the road in the live-action video of the road condition, outputs the navigation path to the display, and stores the navigation path in the recording media so as to realize the effect and aim of live-action navigation.

Description

【Technical field】 [0001] The present invention relates to a navigation device, in particular to a navigation device integrating driving image recording and navigation information. 【Background technique】 [0002] Existing driving video recorders are generally divided into two types, one is to only record the scene in front of the camera lens, sound and the date and time of image shooting, and the other is to record the scene in front of the camera lens, sound and the date of shooting In addition to the time, GPS coordinates, vehicle speed and acceleration are also recorded at the same time. When the former is played, the date and time of image shooting will be displayed in the played video, but this presentation method cannot know the vehicle speed and coordinate position, etc. Driving status; the latter needs to be combined with the playback software provided by the manufacturer to divide the image with date and time, vehicle acceleration data and electronic map that can dis...
