线尺度

The first step is to eliminate all kinds of noises generated in the process of collecting traffic video by means of median filter; Then we finish image sharpening with Laplace operator to clarify edges of the video images; finally, image contrast is enhanced with the help of the second-developing packet SDK-2000, which is provided by our video-collecting card. This way, much more satisfactory images are obtained, and preparation is already made for the following work, thats image analyse.Thirdly, according to the characteristics of our system, mobile objects are distinguished by means of image difference. Then some features such as regional area, length and width of traffic objects are selected and extracted. After processing of scale filter, we successfully recognize those moving vehicles appearing in the monitoring regions.Fourthly, some corresponding algorithms are brought forward to automatically identify those familiar traffic peccancies of many sorts, such as red light violation, yellow-line covering, parking in prohibited spots, over-speed running and converse running. Then we find means to snap pictures and to intercept videos of the spot, and collect a lot of relevant information such as the time, the block, the running direction and the weather conditions and so on. According to this information, our traffic management departments could make correct decisions on punishing those drivers who have broken the traffic rules.Considering the complexity of traffic environments on particular blocks, in order to monitor other traffic peccancies effectively, we also have designed the scheme to carry out traffic monitoring by manual.

首先运用中值滤波法对视频图像进行去噪处理，然后采用二阶差分法进行图像锐化，再通过视频捕获卡携带的二次软件开发包SDK-2000进行对比度增强，从而得到比较理想的图像，为后续的图像分析工作做准备；第三，根据系统特点，通过背景图像差分法，分割出监测区中的运动目标，然后对交通目标的区域面积、长度和宽度等进行特征提取，再经过尺度滤波处理，从而自动识别出机动车辆目标：第四，分别设计相应的算法，实现对闯红灯、压黄线、违章停车、违章超速及违章逆行等常见的交通车辆违章行为的自动识别，并自动抓拍违章现场，截取违章视频，采集其它相关违章信息，为交通执法部门进行交通违章处罚提供有力依据：考虑到特殊路段特殊环境下的交通复杂性，为了有效监控其它类型的交通违章行为，本文还设计并实现了对交通违章的手动监控模式。

Nuclear Physics 1930, the Star of energy will be satisfied with the solution to the rapid development of the internal structure of stars; Hours map and based on the experimental results, the establishment of a stellar evolution of scientific theory. Einstein's general theory of relativity, in 1917 by the structure of the universe, the establishment of a relativistic cosmology. In 1929 the Hubble Space Telescope found redshifts and distances of the future, relations between the people of the gravitational theory of general relativity River from the data objects, size and structure of the material movement and the formation of modern cosmology.

三十年代原子核物理学的发展﹐使恒星能源的疑问获得满意的解决﹐从而使恒星内部结构理论迅速发展﹔并且依据赫罗图的实测结果﹐确立了恒星演化的科学理论。1917年爱因斯坦用广义相对论分析宇宙的结构﹐创立了相对论宇宙学。1929年哈勃发现了河外星系的谱线红移与距离间的关系﹐以后人们利用广义相对论的引力理论来分析有关河外天体的观测资料﹐探索大尺度上的物质结构和运动﹐这就形成了现代宇宙学。
