Embodiment Construction

[0023] Step 1 As shown in FIG. 1 , the augmented reality environment scene is a cube space, and people or other objects interact with augmented reality virtual objects in the cube space. Place a panoramic camera at the point of view in the virtual world to collect panoramic video.

[0024] Step 2 As shown in Figure 2, a flow chart of generating an illumination model by analyzing the panorama is given. The method proposed by the invention includes six steps, namely: panorama image acquisition, texture map of three-dimensional reconstruction model, calculation of panorama light intensity value, light source pattern matching, calculation of light source position and input of virtual object model parameters, and calculation of illumination model.

[0025] Step 2.1 Panoramic image acquisition. Panoramic video is captured using a spherical panoramic camera placed at the viewpoint of a virtual scene.

[0026] Step 2.2 On the basis of the content described in step 2.1, perform textu...

Abstract

The present invention provides a method of generating augmented reality surroundings illumination model by a spherical panoramic camera real time, including: (1) placing the spherical panoramic camera in the augmented reality surroundings, placing in the viewport of the virtual worlds, real-time collecting panoramic picture; (2) processing the texture map having optical property aimed at the real world object after being collected panoramic picture of the step 1; (3) calculating collected panoramagram light intensity value aimed at the virtual world object after being collected the panoramic picture of the step 1, processing illumination model pattern matching, generating virtual world illumination model by the calculation; (4) calculating the illumination model of the augmented reality site under the condition of interactive local impact of the consideration reconstruction model and the virtual object model. The invention real-time generates illumination model in the complex photoenvironment, having advantage of support augmented reality site real time interactive.

Description

technical field [0001] The invention belongs to the field of augmented reality, in particular to a method for real-time generation of realistic graphics applied to computers. Background technique [0002] Augmented reality system is a human-computer interaction system that superimposes or fuses the virtual world on the real world. Since the objects of the system include real-world objects, the system is required to generate realistic geometric models in real time. Lighting models are critical to the generation of photorealistic graphics. [0003] The establishment of the lighting model is mainly based on the relevant laws of optical physics, using a computer to simulate the physical process of lighting in nature. According to whether to consider the reflective characteristics of other objects other than the light source, the illumination model is divided into a local illumination model and a global illumination model. Among them, the local illumination model ignores the e...
