摘要： This invention provides a lens assembly for a vision system, allowing for a constant magnification at various focal distances. The lens assembly resides movably/adjustably along the optical axis relative to the sensor. In an embodiment, the lens assembly includes a fixed rear lens and a front lens that is moved mechanically to focus the object image on the image sensor. The lens assembly can alternatively include a liquid lens that is controlled to adjust magnification with respect to a fixed front lens so as to maintain a constant system magnification. The liquid lens resides between the (fixed) front lens assembly and the image sensor and can be controlled to focus the image onto the image sensor.

摘要： A system and method captures a moving image of a scene that can be more readily de-blurred as compared to images captured through other methods operating on equivalent exposure-time intervals. Rather than stopping and starting the light measurement during the exposure-time interval, photo-generated current is switched between multiple charge storage sites in accordance with a temporal switching pattern that optimizes the conditioning of the solution to the inverse blur transform. By switching the image intensity signal between storage sites all of the light energy available during the exposure-time interval is transduced to electronic charge and captured to form a temporally decomposed representation of the moving image. As compared to related methods that discard approximately half of the image intensity signal available over an equivalent exposure-time interval, such a temporally decomposed image is a far more complete representation of the moving image and more effectively de-blurred using simple linear de-convolution techniques.
摘要翻译：与通过在等效的曝光时间间隔上操作的其他方法捕获的图像相比，系统和方法捕获可以更容易地去模糊的场景的运动图像。不是在曝光时间间隔期间停止和启动光测量，而是根据将解的调理优化到逆模糊变换的时间切换模式在多个电荷存储位置之间切换光电流。通过在存储位置之间切换图像强度信号，在曝光时间间隔期间可用的所有光能被转换成电荷并被捕获以形成运动图像的时间分解表示。与在相当的曝光时间间隔上丢弃大约一半可用图像强度信号的相关方法相比，这种时间分解的图像是运动图像的更完整的表示，并且使用简单的线性去卷积更有效地去模糊技术

摘要： This invention provides a system and method for enabling control of an illuminator having predetermined operating parameters by a vision system processor/core based upon stored information regarding parameters that are integrated with the illuminator. The parameters are retrieved by the processor, and are used to control the operation of the illuminator and/or the camera during image acquisition. In an embodiment, the stored parameters are a discrete numerical or other value that corresponds to the illuminator type. The discrete value maps to a corresponding value in look-up table/database associated with the camera that contains parameter sets associated with each of a plurality of values in the database. The data associated with the discrete value in the camera contains the necessary parameters or settings for that illuminator type. In other embodiments, some or all of the actual parameter information can be stored with the illuminator and retrieved by the camera processor.

摘要： This invention provides a system and method for determining correspondence between camera assemblies in a 3D vision system implementation having a plurality of cameras arranged at different orientations with respect to a scene involving microscopic and near microscopic objects under manufacture moved by a manipulator, so as to acquire contemporaneous images of a runtime object and determine the pose of the object for the purpose of guiding manipulator motion. At least one of the camera assemblies includes a non-perspective lens. The searched 2D object features of the acquired non-perspective image, corresponding to trained object features in the non-perspective camera assembly can be combined with the searched 2D object features in images of other camera assemblies, based on their trained object features to generate a set of 3D features and thereby determine a 3D pose of the object.

摘要： This invention provides a system and method for auto-regulation of parameters a vision system camera and/or associated illumination of objects imaged by the camera using a plurality of differentiated gain (multi-gain) settings on the camera's image sensor to determine the gain value producing the most-readable image.

This image is then read (e.g. decoded) for information contained within any identified features of interest (e.g. found IDs).

摘要： This invention provides a vision system camera, and associated methods of operation, having a multi-core processor, high-speed, high-resolution imager, FOVE, auto-focus lens and imager-connected pre-processor to pre-process image data provides the acquisition and processing speed, as well as the image resolution that are highly desirable in a wide range of applications. This arrangement effectively scans objects that require a wide field of view, vary in size and move relatively quickly with respect to the system field of view. This vision system provides a physical package with a wide variety of physical interconnections to support various options and control functions. The package effectively dissipates internally generated heat by arranging components to optimize heat transfer to the ambient environment and includes dissipating structure (e.g. fins) to facilitate such transfer. The system also enables a wide range of multi-core processes to optimize and load-balance both image processing and system operation (i.e. auto-regulation tasks).

摘要： This invention provides a system and method for estimating the time of a set of pulses based upon a plurality of position measurements of a moving object provided by a non-contacting sensor, such as a one-dimensional optical sensor that tracks movements of object features and reports position measurements with respect to time. Position measurements determine the estimated velocity. The velocity and position measurement allow the timing of a next pulse to be updated, based upon the time of the previous pulse. The pulse is output at the time of the last updated time before the first new position measurement received after the estimated pulse output time. The system allows pulses to be precisely delivered at predetermined motion distances. Where the distance is too short for the measurement rate, the system compares estimated pulse times to clock-generated pulse times and updates the clock-generated pulse times based upon the difference.
