Abstract］ objective to discuss the prevention and treatment of cornea eyewinker.methods to take different measure to eliminate cornea eyewinker.results in 118 cases,the number of complete elimination was 98（83%）,another cases were eliminated completely when they attend the clinic.conclusion cornea eyewinker must take early treatment to remove,tle method is effective with much less side-effect.

目的 探讨角膜异物的预防和治疗。方法采取不同的治疗措施剔除异物。结果 118例中一次取净98例（83%），其余复诊时取净。结论角膜异物应尽早采取治疗措施取除异物，其疗效可靠，不良反应更少。

Digital image processing technology,the present reseach level about image alarm system is to separate eyewinker from monitoring image,and to judge whether the eyewinker is harmful according to the size of the area of object,this method is imprecise and suspectable.The image recgnition alarm system isan apply on image processing technology.when a foreign object enter monitoring place,we will segment、measure object,and analysis、judge through proportion characer or invariant monent.the result of the parameter will decide whether the eyewinker is harmful,if the object is harmful ,system will auto-startalarm device.

而本设计的主要特点是基于了数字图像处理技术，目前传统图像报警系统的研究水平是将异物从监控图像中分离出来，然后依据异物面积的大小来判断异物是否有害，它对异物有害的判断十分不准确，这种判断结果的有效性是很值得怀疑的；针对于这些弊端，本课题在数字图像处理技术上的应用是对监控场所进行全景监控，如有异物进入，对异物进行分割、测量，从不同的角度进行了分析和判断，进而决定异物是否有害，若满足场景所规定的有害条件，则启动报警装置，发出报警信息。

Vidicon collect simulate image in period of time and send to computer or DSP chip through video collection card digitlization,use computer to gain eyewinker and process digital image processing:using image area segment and boder measure to calculate area and perimeter;using image smoothness to wipp offthe infection of yawp;using dynamic background and image suited technology to overcome the infection of ray;calculation the parameter of eyewinker(area, perimeter,round measurement, proportion characer and invariant monent),using least norm to design the linearity classify parts,using image matching technologyto classify eyewinker,and to judge whether the eyewinker is harmful to diff background,if the eyewinker satisfy the character require of harmful object ,system will auto-stsrt alarm device. If there ia not have found any eyewinker, Vidicon will collect new simulate image and make processing.

本设计是将摄像机或高频头采集到的模拟图像经过视频采集卡数字化后送入计算机或DSP芯片，利用计算机对采集到的一定时间段内的图像进行异物获取，并对异物图像进行数字图像处理：利用图像区域分割和边缘检测以便进行面积和周长的计算，利用图像平滑去除噪声的影响，利用动态背景运动检测法和图像配准技术克服光线的影响，并通过异物的各类参数（如面积、周长、圆形度、比例特征和不变矩等）的计算，采用最小范数分类法设计了线性分类器，利用图像匹配技术对异物进行分类，从而判断异物是否有害，针对于不同的背景，若异物满足有害物体的特征要求，则认为物体有害，自动启动报警装置，如果没有发现有害异物则新摄入的图像将取代前一时间段的图像再进行图像处理。

By considering the color randomicity of foreigns and the color difference between the regular materials and the foreigns in fast foreign real-time recognition,the specialities of an One-class Support Vertor Machine for foreign recognition are studied,and an approach to real-time recognition based on hypersphere OC-SVM is presented.

针对高速异物在线识别中正常物料与异物颜色差异及异物颜色随机性的特点，研究了一类支持向量机在异物识别中的特性，提出了一种基于一类超球面支持向量机的在线识别算法。

Clinical data of 178 cases were analyzed retrospectively including the kind of foreign body, predilection site, way of extraction and management as well.

The operations of foreign bodies, including of non-anethesia in 3 cases, direct laryngoscopic operations by local anesthesia with 1% lidocaine or tetracaine in 10 children with infraglottic and behind tracheoal foreign bodies,and operations under general anesthesia in 43 patients were performed.

结果采用无麻醉取出异物3例，用1%利多卡因或丁卡因表面麻醉直接喉镜下取出声门下后气管内异物10例，采用全身麻醉下取出异物43例，56例异物均顺利取出。

Re-sults As for intraocular foreign body,14cases of foreign body（10metallic and3nonmetallic）were displayed and1case of tiny ferrous foreign bodywas not displayed.There were also other cases diagnosed in this way,including of vitreous opacification or hemorrhage in13cases,traumatic detachment of retina in9cases postocular puncture injury and ophthal-morrhexis in2cases dislocation of lens into vitreous cavity,1case.
