If necessary, I can always move the table closer or farther back depending on whatever scanning head. Although, the pencil beam ultrasonic is pretty cool. I will be smoothing the "image" then comparing and combining to several color images from different perspectives, so a very precise resolution will matter less. I think if it can be correct within an inch or two, then I'll be very happy.

Probably around 3 feet. And, The scanner's head should move around  at least   3ft x 3ft (width x height).

Hello, this is my first post.
I want to create something that generates an image with depth instead of color.
If I stand an XY table vertically and attach an ultrasonic sensor at the head, then I could scan each "pixel" at a time.
Does anyone have any recommendations how to do this? Or, is even there a better way to do this?  The setting will be outside during the day, so sensors that require darkness won't be useful.

* I'm trying to keep this under $100. I can use the spare parts of old printers and electronics.
