三维遥感影像立体观察与视差校正仿真软件的研究与开发

Research and Development of Simulation Software for 3D Remote Sensing Images Stereoscopic Viewing and Parallax Refining

摄影测量与遥感课程是遥感科学与技术、测绘科学与技术、地理信息系统等专业的必修课。立体观察是摄影测量与遥感课程中重要理论部分和实验环节。双目视差是产生立体视觉的基础。但是,如果视差太大,将产生复视现象,导致视觉疲劳,所以要进行视差校正。在实验室中,常用的立体观察方式有互补色立体观察、偏振光立体观察等。这些观察方法需要相应的硬件和立体像片;不仅价格昂贵,而且像片和设备容易耗损。三维遥感图像立体观察与视差校正的仿真软件是基于浏览器/服务器模式开发的。任何地方的学生,只要带上红青互补色眼镜,通过浏览器就可以观测到两幅图像合成后的立体影像;视差校正既有模仿硬件观察的手动方式,也有智能的自动校正方式。

Photogrammetry and remote sensing is a main specialized course for the following majors： remote sensing science and technology,surveying and mapping,geographic information system, etc. Stereoscopic viewing is an importantly theoretic and practical training for the course of photogrammetry and remote sensing. Binocular parallax is the basis for generating stereoscopic vision. However,if parallax is larger than eye separation,diplopia or dizziness will occur. Therefore,it is necessary to do parallax refining before conducting stereoscopic observation. The common observation methods in laboratory include anaglyphical stereoscopic viewing and vectograph method of stereoscopic viewing. These methods need not only expensive hardware,but also stereoscopic photos. Simulation software of 3D remote sensing images stereoscopic viewing and parallax refining is developed based on the model of browser / server.Students can observe stereoscopic image by browser without being restricted by time and place as long as they wear a cheap red-cyan 3D glasses. Parallax refining has manual adjusting method and automatic refining way. The manual adjusting method can simulate the operations of hardware observation well.
