Abstract
The utility model discloses a fast structured light scanner of single height of eye, it is acquireed the module and is constituteed by signal transmission module, time schedule control module, structured light generation module, micro -display, projecting lens, imaging lens, image sensor, image data. Signal transmission module and host computer are communicated, and when receiving the collection order back that the host computer sent, control time schedule control module start control structured light generation module and image data is simultaneously acquireed the module and is scanned, and the structured light signal transmission of structured light generation module production is after to the micro -display on, project the testee by the projecting lens with the image on. Simultaneously, the structured light image that imaging lens maked the testee forms images on image sensor's photosurface, and the image that acquires module collection by image data. The synchronization of acquireing by time schedule control module control structure optical projection and image data, but the wide application is in the middle of hand -held type three dimension scanning or industry on -line measuring.
