摘　　要：为解决基于PaperVison3D(PV3D)引擎的全景漫游开发过程中的两个技术难点:热点的不变形、视频的添加和Google Maps功能的添加,在Flash CS5.5平台下,通过推算平面坐标与球面坐标转换的数学公式,结合PV3D引擎中的自带函数和部分类的实例对象完成了场景中热点、视频的不变形添加。在Flex Builder平台下,利用Google Maps提供给Flash的API完成了场景中Google Maps的添加。经实验证明所提方案能良好解决上述技术难点,改善了全景漫游在实际应用过程中的体验效果,增强了沉浸性、交互性,完善了全景漫游系统的部分功能,对于全景漫游技术研究者有一定的借鉴作用。In order to solve the two technical difficulties including the non-deformation addition of hotspots, the addition of video as well as Google Maps in the development process of panorama roaming, based on the PV3D engine, the non-deformation addition of hotspots and video through calculating the conversion formula between the plane coordinates and the spherical coordinates and combining the functions and the instance objects of partial class in the PV3D engine was successfully realized under the platform of Flash CS5.5. Meanwhile, the addition of Google Maps to the scene was solved using the API provided by Google Maps to Flash in the platform of Flex Builder. The methods mentioned can succeed to solve the above-mentioned technical difficulties after experiment. It also improves the visual effect and strengthens the interactivity, immersion and partial functions of the panorama roaming system, which is worthy of the reference for the researchers to some extent.
