Description

一种智能视频监控系统及其监控方法技术领域本发明涉及一种智能视频监控系统及其监控方法,属于数字图像和通信技术领域,是一种能够自动发现、跟踪和识别运动目标,并能结合设定警戒线或警戒区域进行目标行为识别的智能视频监控系统。 An intelligent video surveillance system and monitoring method Technical Field The present invention relates to an intelligent video surveillance system and a monitoring method, and a digital image belonging to the field of communications technology, is capable of automatic discovery, identification, and tracking moving objects, and capable of binding set cordon or warning area intelligent video surveillance system to identify the target behavior. 背景技术随着多媒体技术的发展,以及平安城市建设的需要,视频监控系统正变得日益需要。 With the development of multimedia technology, and the need for safe city construction, video surveillance systems are becoming increasingly necessary. 视频监控系统被用在银行、百货公司、工业区甚至街道。 Video surveillance systems are used in banks, department stores, industrial areas and even streets. 现有技术的视频监控系统典型的是基于以下概念:摄像机被安装在待监视的地区,拍摄的图像序列经过专门的视频线路或者网络传输到控制中心,由专门的监视人员不停地盯着显示屏幕观看,如发现异常情况,则启动报警装置,以便警示犯罪分子,或指派保安人员前去査看,或者同时将传输过来的视频流全部存入硬盘, 以便发生意外后再来査寻先前的录像,为公安部门提供可靠证据。 A typical prior art video surveillance system is based on the following concepts: the camera is mounted in the area to be monitored, the sequence of images captured through the video line or a dedicated network to the control center, constantly watching the display monitor by specialized personnel screen viewing, such as unusual circumstances, the activation of the alarm to alert criminals or security personnel assigned to go see, or will transfer over all video streams to disk, and then to search for an accident the previous video provide reliable evidence for the public security department. 以上所述的是典型传统视频监控系统,它有两个致命的缺点: 一是,监视人员在看显示屏幕约二十分钟就会产生视疲劳,很容易发生漏报警事件;二是, 全部的视频数据存入硬盘,将会占据很大磁盘容量,或者是会利用很大的传输带宽。 The above is a typical traditional video surveillance systems, it has two fatal drawbacks: First, the monitoring personnel will have to see the display screen in visual fatigue for about twenty minutes, it is prone to leakage alarm event; Second, all video data to disk, will occupy a large disk capacity, or will use a lot of bandwidth. 同时,此类视频监控系统不具备智能性,需要专门的监视人员来参与。 At the same time, such a video surveillance system does not have the intelligence, the need for specialized monitoring personnel to participate. 中国专利号为ZL03116154.5的一种异常目标自动发现及跟踪摄像机系统, 能自动跟踪发现视野中的异常目标,在向监控中心报警的同时,能对目标进行自动跟踪,并自动调整镜头放大倍数,得到清晰完整的目标图像。 Chinese Patent No. ZL03116154.5 target an unusual discovery and auto-tracking camera system that can automatically track the target field of view is abnormal, while the alarm to the monitoring center, the target track can be performed automatically, and automatically adjusts the magnification of the lens to obtain a clear and complete picture of the target. 该系统具备了自动发现物体的移动(有人、物体进入)或产生明火、浓烟等情况下视频图像特征变化的异常情况。 The system includes auto-discovery mobile object (someone enters the object) or a case where a video image characteristic abnormal changes in the case of fire, smoke and the like. 但是,在实际情况中,并不是摄像机所拍摄的范围内有运动目标均是异常情况,更多是目标只有在到达某一区域,或者穿过某一位置才被认为是异常情况。 However, in reality, the range is not captured by the camera are moving targets are exceptions, more target only reaches a certain area, or through a certain position was only considered to be anomalies. 基于以上情况,我们提出一种克服传统视频监控系统的弱点,同时比一般智能监控系统更加优越的智能视频监控系统及监控方法。 Based on the above, we propose a video surveillance system to overcome traditional weaknesses, while more superior than the average intelligent monitoring system of intelligent video surveillance systems and monitoring methods.

述实施例l不同的是:它是按博物馆的特点设置。 Example l above except that: it is provided according to the characteristics of the museum. 一般博物馆分布成三大区域-监视区(一般为警戒区域内逗留指定时间即开始报警)、防护区(进入警戒区域内即时或/和在警戒区域内逗留指定时间即开始报警)和禁区(在进入警戒区域时即开始报警)。 General museum distributed into three regions - the surveillance area (usually within a specified time stay alert area began to alarm), the protection zone (within or entering the immediate area warning / alert area and stay within the specified time will start alarm) and restricted (in That began to alarm when entering the warning area). 禁区是指存储、保管防护目标的库房、保险柜、修复室和其它不允许公众出入的区域。 Restricted area means storing, safekeeping protection goals of the Treasury, safe, and other repair room does not allow public access to the area. 我们可以在需要防护的目标(比如墙壁上悬挂供游览者观看的艺术品)设置多边形区域将其覆盖:如果有人进入此展区受保护的艺术品警戒区内超过逗留指定时间即开始报警,同时设置有人将此艺术品取走, 则触发报警规则即时发出警报,以达到实时监视的目标,满足这种要暴露在外而又要防止其被盗走的特殊应用场合。 We can set goals in need of protection (such as works of art hanging on for the tour to watch the wall) polygon area which was covered: if someone enters the protected works of art in this exhibition area of ​​more than stay alert specified time began to alarm, and set this artwork was removed, an alarm is triggered immediate alert rules, in order to achieve the goal of real-time monitoring, to meet this exposed but also to prevent its special applications stolen. 此实例还可应用于机场恐怖分子在敏感区域故意丢弃物品的情况,夜间有嫌疑人在银行外闲荡试图有不轨行为的情况。 This example can be applied to the case of sensitive areas in airports terrorists deliberately discarded items, the suspect in the case of the night hanging around outside the bank has tried to misconduct.

实施例3: Example 3:

本实例是一种用于交通监控的视频监控系统和监控方法,与上述实施例1、 2不同的是:它是为实现交通中的车流量和违规驾驶的监控。 Video monitoring system and a monitoring method of the present example for traffic monitoring, the above-described Example 1, except that the 2: it is implemented in the traffic flow and the traffic violation monitoring driving. 车流量的监控是这样实现的:它是通过计算单位时间内穿过虚拟警戒线车辆的数量来判断路况信息。 Traffic monitoring is implemented: it is judged by the traffic information unit of time the number of vehicles passing through the virtual security line. 处理的大致流程:首先检测出运动前景(运动的车辆),对每个车辆进行跟踪得到其物理中心位置,中心穿过警戒线则计数器加1,最后统计单位时间内的个数便可得知车流量的大小。 Roughly processing flow: First, the motion detecting foreground (a moving vehicle), each vehicle keeps track of its resulting physical center, the center crossing a line counter is incremented, the number of statistical units in the last time that can be the size of the traffic flow. 对于违规驾驶本系统可以识别出车辆超速和车辆闯红灯的两种情况。 For the present driving violations in both cases the system may recognize the vehicle speed and the vehicle running red lights. 车辆超速的监控的实现:同样对检测出的车辆进行跟踪处理,同时结合摄像机的定标信息,计算出两帧间的物体移动实际距离,从而得到车辆的速度判断是否超速。 Monitoring the vehicle speed to achieve: the same vehicle detected tracking process, combined with the camera calibration information, calculate the actual distance of movement of the object between two frames, to determine whether the speed of the vehicle speed obtained. 闯红灯的监控的实现:利用双警戒线,在十字路口的两个斑马线分别设置两条虚拟境界线,在红灯的时间间隔内使其生效,对监控范围内的所有车辆进行跟踪,若有车辆在红灯时同时穿过了两条警戒线则视为闯红灯,因为只穿越第一条警戒线有可能是车辆右拐的情形,而此类情况并不违反交通规则。 Red light monitoring environment: using two cordon provided two virtual boundary lines crossing at two intersections, respectively, to take effect within a time interval of the red, for all vehicles within the scope of monitoring the track, if the vehicle at a red light while passing through the two cordon it is considered a red light, because only through the cordon may be the first case of a vehicle turn right, and such a situation is not in violation of traffic rules. 此实例还可应用于政府办公大楼、奥运会场所、领事馆等。 This example can also be used in government office buildings, Olympic venues, consulates.

本发明的保护范围不限于上述实施例。 The scope of the present invention is not limited to the above embodiments.
