One of the YouTube channels I subscribe to is called Corridor Crew. The channel’s description is “We run a production studio based upon ingenuity, hard work, and friendship. Watch our ups and downs as professional creators!” Its most recent video was about using LiDAR to scan an entire ghost town. WITH A PHONE. Cerro Gordo is now available to view (and in some cases walk through!) at https://poly.cam/cerro-gordo . I watched most of the backstory video with my jaw on the floor. The progress made by LiDAR scanning apps is unbelievable. If you didn’t realize how far phone-based 3D scanning has come, do yourself a favor and watch the video or visit the ghost town online.
KMSP: St. Thomas students develop scanner to create digital archive of tactile images for the blind. “Engineering students from the University of St. Thomas unveiled a scanner they developed to better preserve tactile images created for the blind. When the Minnesota State Services for the Blind transcribes school textbooks into braille, images in textbooks are turned into tactile diagrams, so that a vision impaired reader can feel the image.”
