摘要： A mobile mapping system is designed to generate a geometrically precise three-dimensional detailed model of an unknown indoor environment. There is no limit on the distance the mobile system may travel, nor on the type of details that can be mapped. The same design is used for environments ranging from simple office hallways to long winding underground mine tunnels. Surfaces and features can be mapped from images acquired by a unique configuration of different types of optical imaging sensors and positioning devices. This configuration ensures that all the information required to reconstruct the three-dimensional environment is included in the collected images. Provided a sufficient overlap between two-dimensional intensity images and combining such with three-dimensional range images, the method reconstructs an environment by adjusting a plurality of images simultaneously.

摘要： The present invention is a remote sensing system for real time monitoring of patient position which can report variations in patient setup from day to day as well as motion during individual treatments. In particular, an embodiment of the present invention includes: (a) a source of radiation for applying radiation to a patient; (b) targets affixed to the patient for reflecting radiation impinging thereon; (c) two cameras and a computer for detecting the reflected radiation and for determining the current position of the targets in three-dimensional space; (d) a data store for storing the position of the targets; (e) the computer also serving to compare the current position of the targets with positions stored in the data store; and (f) a display for displaying indicators whenever differences between the current position and the stored position exceed tolerances stored in the data store.
