    • Systems and methods for acquiring and using three-dimensional imaging data to improve the process of scanning bound documents are disclosed. The system includes a camera for capturing an image of documents such as books, and a second camera for gathering data regarding the first camera's field of view. Signal processing logic analyzes the data gathered by the second camera and uses it to determine whether the imaging camera's view was obstructed. If it is determined that the imaging camera's view was obstructed, then remedial action can be taken, such as removing the obstruction, recapturing the image, and/or flagging the image for further processing. The second camera may include a laser range finder, a scanning laser range finder, an ultrasonic range finder, a device that utilizes auto-focus range finding technology, a binocular camera array, and/or a trinocular camera array.
    • 公开了用于获取和使用三维成像数据以改进扫描绑定文档的过程的系统和方法。 该系统包括用于捕获诸如书籍的文档的图像的相机,以及用于收集关于第一相机的视野的数据的第二相机。 信号处理逻辑分析由第二相机收集的数据,并用它来确定成像相机的视图是否被阻挡。 如果确定成像相机的视图被阻挡,则可以采取补救措施,例如去除障碍物,重新捕获图像和/或标记图像以进行进一步处理。 第二照相机可以包括激光测距仪,扫描激光测距仪,超声波测距仪,利用自动对焦测距技术的设备,双目相机阵列和/或三目相机阵列。

    • Systems and methods for pacing and error monitoring of a manual page turning operator of a system for capturing images of a bound document are disclosed. The system includes a speaker for playing music having a tempo and a controller for controlling the tempo based on an imaging rate and/or an error rate. The operator is influenced by the music tempo to capture images at a given rate. Alternative or in addition to audio, error detection may be implemented using OCR to determine page numbers to track page sequence and/or a sensor to detect errors such as object intrusion in the image frame and insufficient light. The operator may be alerted of an error with audio signals and signaled to turn back a certain number of pages to be recaptured. When music is played, the tempo can be adjusted in response to the error rate to reduce operator errors and increase overall throughput of the image capturing system. The tempo may be limited to a maximum tempo based on the maximum image capture rate.
    • 公开了用于捕获绑定文档的图像的系统的手动翻页操作者的起搏和错误监视的系统和方法。 该系统包括用于播放具有速度的音乐的扬声器和用于基于成像速率和/或错误率来控制速度的控制器。 运营商受到音乐节奏的影响,以给定的速率捕获图像。 替代或除了音频之外,可以使用OCR来实现错误检测以确定页码以跟踪页面序列和/或传感器来检测诸如图像帧中的物体侵入和不足的光的错误。 操作者可能会收到音频信号的错误信号,并发出信号以返回要重新捕获的一定数量的页面。 当播放音乐时,可以响应于错误率来调整速度以减少操作者错误并增加图像捕获系统的总吞吐量。 基于最大图像拍摄速度,速度可能被限制在最大速度。

    • Systems and methods for moving a document cradle to facilitate imaging of a bound document are disclosed. The system may include a cradle supporting a document, such as a book, a cradle positioner for selectively positioning the cradle relative to a camera, and a controller for controlling the positioner to automatically position the cradle based on the location of the page being imaged relative to the camera. The cradle may be positioned such that a gutter of the book or a surface plane of each page being imaged remains in approximately the same position relative to the camera. The cradle positioner may include a servo motor controlling a shaft to position the cradle supported and guided by a bearing. A sensor (e.g., 3D camera, range finder, laser, and/or edge detector) may be provided to facilitate the controller in controlling the cradle positioner based on the location of the page being imaged relative to the camera. The controller may control the positioner based on, for example, current page count tracked by the controller, total number of pages, thickness of the book, width of the gutter of the cradle, and/or weight of the book exerted on one or both sides of the cradle.
