摘要： Disclosed are methods and apparatus for automatic optoelectronic detection and inspection of objects, based on capturing digital images of a two-dimensional field of view in which an object to be detected or inspected may be located, analyzing the images, and making and reporting decisions on the status of the object. Decisions are based on evidence obtained from a plurality of images for which the object is located in the field of view, generally corresponding to a plurality of viewing perspectives. Evidence that an object is located in the field of view is used for detection, and evidence that the object satisfies appropriate inspection criteria is used for inspection. Methods and apparatus are disclosed for capturing and analyzing images at high speed so that multiple viewing perspectives can be obtained for objects in continuous motion.

摘要： Disclosed are methods and apparatus for automatic visual detection of events, for recording images of those events and retrieving them for display and human or automated analysis, and for sending synchronized signals to external equipment when events are detected. An event corresponds to a specific condition, among some time-varying conditions within the field of view of an imaging device, that can be detected by visual means based on capturing and analyzing digital images of a two-dimensional field of view in which the event may occur. Events may correspond to rare, short duration mechanical failures for which obtaining images for analysis is desirable. Events are detected by considering evidence obtained from an analysis of multiple images of the field of view, during which time moving mechanical components can be seen from multiple viewing perspectives.

摘要： This provides a plurality of novel features that can be applied variously to a reader. In one embodiment, the light pipe is constructed from durable polycarbonate for increased shock resistance and can define a rectangular cross section. The chamfered end of the light pipe is textured or frosted to further diffuse refracted light passing through the end so as to present a more even effect. The conical/tapered diffuser within the light pipe is illuminated by a reflector with a white textured surface that reflects a plurality of rearward-directed illumination sources back into the diffuser. The reflector can define a predetermined cross section that directs further light into the forwardmost, remote regions of the diffuser to generate a better spread of light and alleviate spotting effects. The textured surface on the chamfered light pipe end can be employed to better project indicator light. The illumination sources are arranged in a ring at the inner end of the pipe, and can be multi-colored sources that respond to the controller to project and appropriate color and/or blink in an appropriate pattern to indicate various conditions, such as read success or failure. The controller is adapted to provide indications between image acquisitions. The controller can operate individual portions of the ring so that only corresponding portions of the light pipe perimeter are illuminated in a particular color (quadrants, for example) at a given time. Different quadrants may be simultaneously illuminated in different colors in one example.
摘要翻译：这提供了可以不同地应用于读取器的多个新颖特征。在一个实施例中，光管由耐用的聚碳酸酯构成，以提高抗冲击性并且可以限定矩形横截面。光管的倒角端被纹理化或磨砂，以进一步扩散通过端部的折射光，以产生更均匀的效果。光管内的锥形/锥形扩散器由具有白色纹理表面的反射器照射，该表面将多个后向照明源反射回扩散器。反射器可以限定预定的横截面，其将更远的光引导到扩散器的最前面的远程区域中，以产生更好的光散射并减轻斑点效应。倒角光管末端的纹理表面可用于更好地投影指示灯。照明源在管的内端设置成环形，并且可以是多色源，其响应于控制器投射和适当的颜色和/或以适当的图案闪烁以指示各种条件，例如读取成功或失败。控制器适于在图像采集之间提供指示。控制器可以操作环的各个部分，使得在给定时间内只有光管周边的相应部分以特定颜色（例如象限）被照亮。在一个示例中，不同的象限可以同时以不同的颜色照亮。

摘要： A system and method is provided for selectively controlling the illumination, and particularly dark field illumination, applied to a symbol to be decoded, and for determining a suitable or optimized level of lighting for decoding the symbol. A ring-shaped illuminator is provided, and is segmented into a plurality of individually-controllable lighting portions which can be, for example, quadrants. Initially, illumination is provided to the symbol through an initial set of lighting conditions. Feedback from acquired image data is then used to determine whether the lighting is suitable for decoding the symbol and, if not, a controller varies the lighting applied to the symbol, and additional image data is acquired. This process is continued until suitable conditions are met. Alternatively, activation and deactivation of the lighting segments can be manually selected by an operator to provide suitable conditions.

摘要： A method is presented for processing an image of a two-dimensional (2D) matrix symbol having a plurality of data modules and a discontinuous finder pattern, each distorted by “donut effects”. A resulting processed image contains an image of the 2D matrix symbol having a continuous finder pattern suitable for conventional 2D matrix symbol locating techniques, and having a plurality of data modules, each data module having a center more truly representative of intended data, and suitable for conventional 2D matrix symbol sampling and decoding. The method includes sharpening the distorted image of the 2D matrix symbol to increase a difference between low frequency and high frequency image feature magnitudes, thereby providing a sharpened image, and smoothing the sharpened image using a moving window over the sharpened image so as to provide a smoothed image, the moving window and a module of the 2D matrix code being of substantially similar size.
摘要翻译：提出了一种用于处理具有多个数据模块和不连续取景器图案的二维（2D）矩阵符号的图像的方法，每个数据模块和不连续取景器图案都被“环形效应”扭曲。所得到的经处理的图像包含具有适用于常规2D矩阵符号定位技术的连续取景器图案的2D矩阵符号的图像，并且具有多个数据模块，每个数据模块具有更真实地代表预期数据的中心，并且适于常规2D矩阵符号采样和解码。该方法包括锐化2D矩阵符号的失真图像以增加低频和高频图像特征量之间的差异，从而提供锐化的图像，并且使用在锐化图像上的移动窗口来平滑锐化的图像，从而提供平滑的图像，移动窗口和2D矩阵代码的模块具有基本相似的大小。

摘要： A stereo imaging based vision system to monitor the area on the two sides of either a door and control door motion according to the motion of 3D objects in the viewing area. The system calibrated to provide heights above the ground plane for any point in the field of view. Therefore, when any object enters the field of view, it generates interest points called “features”, the heights of which are measured relative to the ground plane. These points are then clustered in 3D space to provide “objects”. These objects are then tracked in multiple frames to provide “trajectories”. Such a system could then control the door motion (open, close, stall) based on the various pieces of information generated about the object.

摘要： A method is provided for detecting spot defects on an object when an allowable variation (called the “background”) in the appearance of the object can be modeled. Methods are also provided for measuring and classifying detected spot defects. An alignment model is used to align the image of the object, a background model is then used to estimate the (possibly different) background in each region, and each background is substantially removed from the image so as to form a foreground image on which blob analysis can be applied to detect spot defects, the blob analysis using a threshold image that accommodates different noise statistics for each region. The method facilitates robust spot defect inspection of fiber optic end faces, or of any object with different object regions. The method also allows use of blob analysis over a larger range of conditions, including conditions that make simple blob analysis infeasible.
