kinstats

Part of a collection of Kinect hacks and tools by Mike Bourgeous.

kinstats displays some very basic statistics about the data coming from a Kinect sensor's depth data, including the minimum, mean, median, and maximum, the percentage of shadowed or out-of-bound depth pixels, etc. kinstats can also repeatedly output a single statistic, intended for piping into other programs.

Requirements

You will need libfreenect from the OpenKinect project to compile kinstats.

Compiling and Running

$ make
$ ./kinstats

Command-line Options

Usage: ./kinstats -[mMaAv]
Use one of:
	m - median
	M - scaled median
	a - mean
	A - scaled mean
	v - verbose (default)

Sample Output

kinstats.c:113: depth():	Time: 3523477067, min: 320 (177, 37), max: 1046 (407, 79)
kinstats.c:118: depth():	Out of range: 21% mean: 783.504150 (1.129089), median: 820 (1.283301)
