I think you guys are giving 3d scanning too much credit. It has its merits sure, and there is definitely certain fields it can totally revolutionize. But traditional CAD and Polygon modelling are nowhere near on their way out.
[QUOTE=alexaz;43761931]... You are not gauging the size of the dot, you are measuring the distance between the center point of the camera and the laser dot ( since I initially said [del] that the laser was at an angle [/del] trigonometry).

OpenCV is used here, but only because it was faster than doing it yourself.[/QUOTE]

nice look at that sick 3d mesh generation bruh great end result, he generated a 3d mesh of his room, looks great.
that's not even a 3d mesh. the title of the video is 2d map generation. it uses a laser and a camera mounted on a motor to find a 2d boundary map of the room you're in, it's completely different, way simpler, and the results are still complete garbage. great choice of video to prove my point.
is the pineapple image an actual scan from the phone bc if so i'm impressed
also everyone who thinks 3d scanning at any decent level of quality is easy and inexpensive must have had little experience with it. it's not.
Pretty damn sure the concept of taking multiple images of a well lit object from different angles and turning it into 3D models isn't new at all.
I remember a piece of software that could the same, although te user had to define the basic lines and shape on the object in order to "teach" the program before it cranked out a model.
But that also worked surprisingly well.
If you can manage a decent 3d model from using laser and a webcam to scan you should get some sort of medal.

I modeled my head with some software back around 2000 (that got acquired then vanished later on). It was good for the little data it took in, and even rigged up full features and let me mocap pretty accurately with a crappy webcam
the technology has been around in various forms for a long while, the accuracy and power has only recently been reinvigorated by the VR/AR movements
