Display control method, device, and equipment for depression angle of electronic map

Abstract

The invention belongs to the navigation field, and provides an electronic map looking down angle display control method and equipment, and the said method comprises: receiving the switch instruction of the electronic map looking down angle, switching the corresponding prospective projection calculation function, and generating the local three dimensional guide navigation image through the location data and three dimensional data of the surrounding equipment, displaying the said three dimensional guide navigation image. It is used in navigation field, provides an electronic map looking down angle display control method and equipment, and the said method goes like this: receiving the switch instruction of the electronic map looking down angle, switching the corresponding prospective projection calculation function, and generating the local three dimensional guide navigation image through the location data and three dimensional data of the surrounding equipment, displaying the said three dimensional guide navigation image. It increases guide navigation effect, meeting the requirement of multi perspective observation of consumers.

Description

technical field [0001] The invention belongs to the field of navigation, and in particular relates to a display control method, device and equipment of an electronic map overlooking an angle. Background technique [0002] The Global Positioning System (GPS) uses navigation satellites for timing, positioning and ranging, and can provide all-weather, all-round and continuous real-time high-precision three-dimensional space and speed for users at sea, land and air all over the world. and time information. The system is mainly composed of three parts, namely the space part, the ground control part and the user device part. The space part is composed of 24 satellites, which are distributed in 6 track planes. The ground control part is composed of the main control station responsible for managing and coordinating the work of the entire ground control system, the ground antenna that injects the search message into the satellite under the control of the main control station, the m...
