Real-time display of images acquired by a handheld scanner |
摘要 |
A computer peripheral that may operate as a scanner. The scanner captures image frames as it is moved across an object. The image frames are formed into a composite image based on computations in two processes. In a first process, fast track processing determines a coarse position of each of the image frames based on a relative position between each successive image frame and a respective preceding image determine by matching overlapping portions of the image frames. In a second process, fine position adjustments are computed to reduce inconsistencies from determining positions of image frames based on relative positions to multiple prior image frames. As a result, a composite image of an object being scanned may be presented in real time to a user, providing a user feedback or portions of the object that have been scanned and those that have not. |
