Cross-screen and cross-platform measurable live-action map organization method

Abstract

The invention discloses a cross-screen cross-platform measurable live-action map organization method. The method comprises the following steps of: separation of a front end and a rear end: establishing a front end and rear end separated desktop end live-action map web application framework; cross-platform general function: adopting a response type layout scheme and a touch screen compatibility function-supported browser in a two-dimensional layout structure of a live-action map application; mobile end exclusive function: packaging a Webkit and a V8 kernel in a native application container, andunifying compatibility, for an HTML5 standard, of a mobile end and a desktop end; and packaging a local function interface and a file reading / writing access interface of the mobile end through a self-defined interface, and self-defining a communication standard to realize a bidirectional calling mechanism of JavaScrip and Java of the mobile end. According to the method, once development and multi-platform deployment of multi-platform general functions are realized, personality characteristics of mobile platforms can be considered, and local function interface of the mobile platforms can be seamlessly called, so that measurable live-action map using experience similar to native applications can be provided.

Description

Technical field [0001] The invention relates to the technical field of a method for organizing a measurable real-scene image map of surveying and mapping geographic information, in particular to a cross-screen and cross-platform method for organizing a measurable real-scene image map. Background technique [0002] Street View uses panoramic cameras and positioning equipment to record the field image information of the position sequence. Users can only get the visual model of the predetermined position and the rough space model based on a limited number of positioning points. [0003] The measurable real image is based on the basic display principle of street view, and at the same time, three-dimensional surface position information along the line is collected through vehicle-mounted or ship-borne mobile measurement technology. It has a relatively complete geographic space model and can support spatial analysis operations in three-dimensional scenes. [0004] Traditional street view s...

Problems solved by technology

The script execution performance of the mobile browser is not enough to support the local query and retrieval of 3D spatial data. As a result, the existing general-purpose street view or measurable real-scene mobile applications usually do not have the ability to run offline

[0014] d) Web applications coupled with traditional front-end and back-end business logic cannot be compatible with the use of mobile offline scenarios
