摘要： Disclosed is a method and a scanning device for digital image scanning of a surface of an object. The scanning device comprising a light source for illuminating the object. The scanning device comprising a first image sensor configured for capturing a first set of images of a first region of the object, where the first region is illuminated by the light source. The scanning device comprising a second image sensor configured for capturing a second set of images of a second region of the object, where the second region is illuminated by the light source. The scanning device comprising a laser component configured for projecting laser light onto the object. The projected laser light has a shape of a cross on the object. The first image sensor and the second image sensor are configured to capture/cover an overlapping region on the object. The overlapping region comprising a part of the first region of the object and a part of the second region of the object. The laser light from the laser component is configured to be projected onto the overlapping region. The first image sensor and the second image sensor are configured for capturing a third set of images and a fourth set of images, respectively, of the object including the projected laser light on the overlapping region.

摘要： A method for estimating distance to an object in a scene using an imaging system (400) comprising a camera array (410) with multiple imagers (540), an image processing pipeline module (420) and a controller (440). The image processing pipeline module (420) comprises an upstream pipeline processing module (510), an image pixel correlation module (514), and a parallax confirmation and measurement module (518). Images (412), including a current image, captured by the multiple imagers (540) are provided to the upstream pipeline processing module (510) for processing. The image pixel correlation module (514) aligns portions of images, including the current image, captured by different imagers of the multiple imagers to compensate for parallax. The parallax confirmation and measurement module (518) processes the current image to detect and measure the parallax. Distance to an object in the scene is determined using the measured parallax.

摘要： A document reading device includes an imaging unit that images a document, a placing portion that includes a first placing portion and a second placing portion and that has a placing surface on which the document is placed, the placing surface being formed by the first placing portion and the second placing portion, and a detector that detects an edge of the document that is placed on the placing surface by using a color difference or a luminance difference between the placing surface and the document. An end portion of the first placing portion adjacent to the second placing portion extends toward the second placing portion beyond an end portion of the second placing portion adjacent to the first placing portion.

摘要： There is described an imaging device for capturing images of at least portions of moving objects. The system comprises a stationary camera lens configured for reproducing an image of at least a portion of each moving object in an imaging plane when said object moves across a capturing region. The device further comprises at least one image sensor located in the imaging plane for receiving the reproduced image of the at least a portion of the corresponding moving object and converting said image into electronic signals. The at least one image sensor is mounted on a sensor support adapted to be actuated in a manner that the at least one image sensor is moved in the imaging plane relative to the stationary camera lens, and in a manner that the motion of said at least one image sensor is synchronized with the motion of the moving object to be captured. This ensures that there is substantially no relative movement between the reproduced image in the imaging plane and the image sensor when said moving object moves across the capturing region. As a result motion blur of the captured image of the at least a portion of each moving object is prevented or significantly reduced.
