The invention provides a full-scene combined navigation and positioning method, and relates to the technical field of navigation. The full-scene combined navigation and positioning method specifically comprises the following steps: 1, inputting continuous intersection positions into an error-prone intersection input module, carrying out horizontal plane modeling on a three-dimensional road surface, and layering roads at different layers; and 2, when a automobile runs on the road surface, identifying whether the position of the automobile is an overpass with complex road conditions through a vehicle position positioning module, if the position of the automobile is the overpass, judging the level of the overpass at the position of the automobile through a vehicle position surface identification module by utilizing a planned route, and realizing accurate navigation, and if the vehicle position surface identification module identifies that the position surface is incorrect, and selecting a correct position surface through a vehicle position surface manual correction module. According to the invention, the complex intersection navigation is accurate during Beidou satellite navigation, the multi-layer flyover can realize accurate positioning of the flyover where vehicles are located, and the Beidou satellite navigation accuracy is greatly improved.

    本发明提供一种全场景组合导航定位方法,涉及导航技术领域。该全场景组合导航定位方法,具体定位方法如下:步骤一.对连续路口位置录入到易出错路口输入模块,且在立体路面进行水平面建模,将不同层面的道路进行分层;步骤二.汽车行驶在路面时通过车辆位置定位置模块识别车辆所在位置是否为路况复杂的立交桥若为立交桥利用规划路线通过车辆位面识别模块判断车辆位置立交桥的层面,并实现精准导航,若车辆位面识别模块识别位面不正确时,通过车辆位面手动纠正模块选择正确的位面。本发明使得北斗卫星导航时复杂路口导航精准,且多层立交桥可以实现车辆所在立交桥的精准定位,大大提高了北斗卫星导航精度。
