Capturing data involves repetitive steps. slcapture
exists to automate these steps so that the operator can stay sane.
The two important steps are:
-
displaying a specific pattern
-
taking a timed image of said specific pattern
Given 1)
a list of patterns and 2)
images taken by a camera viewing each pattern, it's possible to reconstruct various properties of a scene. Color and depth are two commonly sought values to reconstruct. After data is collected, it can be processed by slcrunch
.
A single "scan" consists of a folder (e.g. scan_0001
) with one or more images, along with a list.yaml file which describes the order.
scan_0001/
scan_0001/img_0.jpg
scan_0001/list.yaml
