扫描全景方法在现场照相中的应用与分析

The Application and Analysis of Panoramic Scanning in Scene Photography

回转连续拍照法是现场照相常用的一种方法。但这种方法对拍摄和图像处理技术要求高,难以推广和普及。扫描全景方法具有操作简单、成像质量好、成功率高的特点。试验表明,在拍摄距离不变或空间大小受到限制的情况下,为了扩大现场的取景范围,与广角镜头和超广角镜头相比,采用扫描全景方法拍照是一种最佳的选择。因此,它可以完全取代回转连续拍照法,非常适用于现场方位照相和现场概貌照相。

Turn- around- successive photography method is commonly applied in scene photography. However,this method could be hardly promoted and popularized for its high requirements on shooting and image processing technique. By contrast,panoramic scanning is characterized as simple operation,good image quality and high success rate. Experiments indicate that under constant shooting distance or limited space,in order to extend the frame of the scene,panoramic scanning would be the best choice compared with wide angle lens and ultra wide angle lens. Therefore,it can completely replace turn- around- successive photography and is highly applicable for azimuth photography and survey photography of crime scene.
