Systems and methods for generating composite images of long documents using mobile video data

摘要

Systems, methods, and computer program products are disclosed and include: initiating a capture operation using an image capture component of the mobile device, the capture operation comprising; capturing video data; and estimating a plurality of motion vectors corresponding to motion of the image capture component during the capture operation. The systems, techniques, and computer program products also include detecting a document depicted in the video data; tracking a position of the detected document throughout the video data; selecting a plurality of images using the image capture component of the mobile device, wherein the selection is based at least in part on: the tracked position of the detected document; and the estimated motion vectors; and generating a composite image based on at least some of the selected plurality of images.

主权项

1. A computer program product comprising a non-transitory computer readable medium having stored thereon instructions executable by a mobile device, the instructions being configured to cause the mobile device, upon execution thereof, to:
initiate a capture operation using an image capture component of the mobile device, the capture operation comprising;
capturing video data; andestimating a plurality of motion vectors corresponding to motion of the image capture component during the capture operation; detect a document depicted in the video data; track a position of the detected document throughout the video data; select a plurality of images using the image capture component of the mobile device, wherein the selection is based at least in part on:
the tracked position of the detected document; andthe estimated motion vectors; and generate a composite image based on at least some of the selected plurality of images.
