Abstract
The invention discloses a kind of online panorama displayings of three-dimensional scenic digital space model, immersion roams, the realization method and system of human-computer interaction, it is proposed " three-dimensional scenic --- two dimensional image " mapping method based on globular projection, by more three-dimensional spatial information descriptions such as depth in bidimensional panoramic picture and subsidiary description file, it can only show that being unable to immersion roams to breach traditional 360 ° of panorama sketch, the defect of human-computer interaction, it forms one and extracts plot quality height, the big novel 360 ° of panoramas displaying of camera degree of freedom and immersion roaming technology, and in displaying and the new function that human-computer interaction is added on the basis of roaming, to meet application need for a business.
Description
Technical field
The invention belongs to three-dimensional scenic digital space model immersed system of virtual reality fields, more particularly to three-dimensional
Panorama renders, the displaying of online panorama, immersion roams and the panorama of human-computer interaction function browses system.
Background technology
The displaying field in 3-dimensional digital space, the method that conventionally employed 3 d modeling software makes roaming video, with video
The mode of broadcasting is browsed for observer, and video recording must be shot according to the route that producer has planned, can not be by the meaning of observer
Hope is controlled.As an improvement, Google's streetscape product of Google's research and development, provides 360 ° of observations to global streetscape photo and roaming work(
Can, it provides a kind of height and freely watches experience, but only drawback is that, Google's streetscape is only applicable to the open air shot on the spot
Streetscape.
, there are two technology paths in digital scene display field indoors at present：(1) real-time rendering scheme, using client
Real-time Rendering Technology, it is disposable to load large scene model data by powerful three-dimensional hardware computing capability, it is inputted according to user
Camera position real-time rendering is adjusted, camera degree of freedom is high, can move camera parameter in any way, but due to current computer
Real-time rendering ability is unable to reach physical third dimension, can not accomplish refraction effect, indirect lighting and other effects, so scheme goes out figure effect
Fruit is poor and real pictures or 3D effect figure have certain gap, is used generally as sketch preview；(2) panorama sketch scheme uses
High quality design sketch Rendering of the tradition based on ray tracing, including three panorama picture formation, storage and displaying links, pass through
Certain projection rule renders one or more design sketch in the fixed camera position of scene, is realized further according to projection rule
Around displaying.Projection be divided into the classifications such as cylindricality, spherical shape, box-like, regular dodecahedron, be corresponding with respectively different panorama picture formations,
Storage and display form.Compared to real-time rendering scheme, this scheme improves out plot quality, but since method needs to lock camera
Position, to reduce observation degree of freedom.Design field indoors, panorama sketch are the design sketch ways of presentation of prevalence instantly.
With the expansion of three-dimensional internet business demand and the promotion of linking Internet speed, there is an urgent need for one kind to make in market
With convenient, fast, available online scene display system, demand is shown to meet online three-dimensional scenic at present, to above-mentioned tradition
Technical solution is a challenge.
Invention content
In order to solve the problem above-mentioned, the present invention is on the basis of two kinds of traditional schemes, in conjunction with the advantages of them, proposes base
In " three-dimensional scenic --- two dimensional image " mapping method of globular projection, by more three-dimensional spatial information descriptions such as depth two
Tie up in panoramic picture and subsidiary description file, to breach traditional 360 ° of panorama sketch can only show be unable to immersion roaming,
The displaying of novel 360 ° of panoramas and immersion roaming that plot quality is high, camera degree of freedom is big are extracted in the defect of human-computer interaction, formation one
Technology, and in displaying and the new function that human-computer interaction is added on the basis of roaming, to meet application need for a business.
The present invention selects globular projection method, and comparison other methods globular projection is continuous with projection formula, seam is few
Feature, and on the basis of basic panorama displaying, depth calculation, coordinate calculating etc. are extended, to meet immersion roaming and people
The requirement of machine interaction function.
The present invention provides a kind of automation storage process flow for indoor and outdoor model of place, including automation phase
Machine generation method, the panorama sketch rendering intent with depth, based on JavaScript scripts can I-goal behavior description with lead
Go out method, the network relation storage method of panorama sketch.
The present invention provides a kind of panorama displaying for indoor and outdoor scene and roams flow with immersion, including based on light
The target selecting method of line tracking, ground running method, gradual Shot change method.
The present invention provides a kind of public service agreement, and agreement enormously simplifies third-party application and provides service to this system
Call flow.
