Method of aligning light projector with electronic model in environment
A recently granted patent (Publication Number: US11921409B2) discloses a method and system for aligning a light projector and an electronic model in an environment. The method involves placing the light projector in the environment, projecting a visible scan-box to mark a portion of the environment, acquiring an intensity image, identifying point targets, associating them with points in the electronic model, aligning the light projector to the model, measuring the angle of rotation, and realigning based on the measured angle. The system includes a light projector with a beam-steering system and an optical detector, along with processors to execute the alignment method.
Furthermore, the patent details additional features such as refining point target locations through multiple intensity scans, automatically detecting point targets, checking for drift by comparing actual and expected positions of targets, and utilizing a laser scanner to obtain three-dimensional coordinates for surface extraction and topographical curve generation. The system also includes an inertial measurement unit for measuring rotation angles and realigning the projector accordingly. A computer program product is also described, enabling the execution of the alignment method and additional functionalities like periodic intensity image acquisition, retroreflective target identification, and surface projection based on topographical curves. Overall, the patent presents a comprehensive approach to aligning light projectors and electronic models in various environments, enhancing accuracy and efficiency in projection applications.
