The first-time observer of a bonsai is often fascinated in seeing what could be a large tree in a miniature size, If one takes the next step of acquiring a bonsai, the young tree in a pot can lead the imagination on endless journeys to mystical places-old-growth forests, windswept cliffs or lush green valleys.

第一次看到盆景的人都会非常着迷：一颗大树竟能容于方寸之间。如果这个人进而得到一盆盆景，盆中的小树会引发他无尽的遐想：神奇仙境，古老的山林，风蚀的悬崖或者郁郁葱葱的峡谷。

Red cliff peninsulas and islands, and deep canyons led off in all directions.

According to the function of distributed emulator, optical information processing and image multi-object tracking system, the following three aspects were emphasized in this dissertation. Firstly, a vast virtual terrain, ground radar models and canyons were created for the distributed emulator with modeling software Creator. The radars were driven to scan during emulating and the real time terrain code was sent to Radar module. Secondly, an optics channel simulating the optics camera of a virtual aircraft was implemented with simulating software Vega. The 2-D information got from the channel was translated and sent to multi-sensor information fusion system as an optics information source. Thirdly, the dissertation studied some motion estimation methods and analyzed the factors which influence the speed and the precision of the block matching algorithms. Then an improved block matching method was proposed for image multi-object tracking system and applied in the system combined with frame difference method.

论文根据多传感信息融合实验系统中的分布式飞行仿真系统、光学信号处理器和图像多目标跟踪系统三个子系统的功能要求，具体完成了以下三方面的工作：首先利用建模软件Creator创建分布式飞行仿真系统中的大面积地形、场景中的地面雷达模型和峡谷地形，并在仿真过程中实时驱动雷达模型的扫描，同时为后续雷达仿真模块提供实时地形编码；其次利用仿真软件Vega，在分布式仿真系统中为光学信号处理器设计实现了光学通道，模拟飞行器的光学摄像机的功能，并且对由此通道获得的目标二维光学信息进行转化处理，作为光学信息源发送给后续的多传感信息融合器；最后针对图像多目标跟踪系统，在研究图像分割运动估计算法的基础上，通过分析影响块匹配算法速度和精度的因素，改进了块匹配运动估计算法，结合差分法可应用到目标跟踪系统中。

A land of h eavy forests （311 million h ectares） and barren deserts, of h ig h -peaked mountains （McKinley rises to 6,300 meters） and deep canyons, America also en j oys bountiful rivers and lakes.

除许多森林（达3、11亿公顷）、荒芜的沙漠、多高峰的山脉（麦金莱山海拔6300米）和深深的峡谷以外，美国还有很多河流和湖泊。

After a brief walk through wind-worn ravines, the scene opened up into a sprawling desert with no shortage of enemies who weren't too please to see me there.

走了没一会儿穿越风蚀峡谷，场景进入到延绵的沙漠地带，那里有无数想置我于死地的敌人。

And then, for 3D model, the wind speed and wind pressure distributing of single hill with diverse slope is researched. Based on it, the principle and process of narrow channels effect forming is showed visually and the change of airflow field in the valley and out of the valley under different wind angle is studied.
