基于图像数据库的动态场景生成系统

Dynamic scenes generation system based on image database

实现各类目标和背景下动态场景的计算机编辑和生成 ,首先应对组成动态场景的要素进行分析 ,即目标、背景、目标运动规律和特殊事件四个要素 ,然后通过编程由四个模块完成相应功能。目标、背景编辑模块可对目标、背景图像进行各种处理 ,并对重要特征量进行计算。运动路径模块可指定目标的运动规律 ,包括路线、大小和角度变化等。特殊事件模块可加入独立于目标的各类典型事件 ,如运动的干扰物等。最后通过动态场景合成由计算机自动生成所需的动态场景图像。所需的原始目标、背景图像来源于图像数据库管理系统 。

Computer editing and generating of dynamic scenes of various targets and backgrounds have been actualized. At first, four elements composed the scenes are analyzed, i.e., target, background, moving pattern and special events. Then they are programmed into four modules to fulfil corresponding tasks. In the target and background modules, the images are processed and interest parameters are calculated. In the moving pattern module, the pattern is specified. In the events module, some typical events independent of target can be added. At last, using the synthesizing techniques, the required dynamic scenes are automatically generated by computer. The original target and background images can be easily got through the image DBMS.
