===Introduction===

The Kinect plugin transfers the images from the Kinect sensor to image-pool images, and thus allow data users to utilize the image pool functions - like poolpush - to be updated with new data as they arrive.

===Configuration===

The camera parameters are stored in the camera pool, default as device 18 and 19, and can be set like:

module load="aukinect.so.0"
module load=aucamrectify.so.0
camset device=18 name=kinectcolor
camset device=19 name=depth
var campool.device18.intrinsic="525.829, 0.0, 322.205; 0.0, 525.829, 257.529; 0.0, 0.0, 1.0"
var campool.device18.distortion="0.24042, -0.72509, -0.00018, -0.00022, 0.72285"
var campool.device19.intrinsic="595 0 320; 0 595 240; 0 0 1"

The shown parameters for device 18 (color camera) is based on a calibration on one of our devices, and should be fairly representative.
The values for the IR sensor is a fairly rough guess - should be improved - when you have better data, please mail it to me ( jca@elektro.dtu.dk ).

The kinect plugin has the following configuration variables of its own:

kinectNumber=0 (r/w) kinect number to be used on next open
updCnt=70 (r) Number of updates
desiredFramerate=2 (rw) desired framerate (frames/sec) for both depth and
color
measuredFramerate=2 2 (r) [color, depth] measured framerate (frames/sec)
desiredResolution=1 (rw) desired resolution 0=low (QVGA), 1=medium (VGA), 2 =
high)
imagesC3D=18 19 20 21 (rw) Image pool for [0] color, [1] depth (16bit), [2]
depth (RGB)image, [3] depth 8-bit BW
camDeviceNum=18 19 (r/w) index to camera info - [color, depth]
imgIR=0 (r/w) is IR (dot) image to replace color image [0=color,
1= IR]
useColor=1 1 (rw) [0]=1 request color (at next open), [1]=1 is in use
useDepth=1 1 (rw) [0]=1 request depth (at next open), [1]=1 is in use
useDepth8bit=1 (rw) make 8-bit BW image from depth -1 = no image, 0-8
subtracts 512 and shift 0-8 bits
useDepthColor=0 (rw) make RGB pseudo color image from depth 0=do not make
open=1 1 (rw) [0]: set to 0 to close set to 1 to open, [1]:
0:isclosed 1:isopen
initialized=1 (r) is the camera initialized
tiltDeg=0 (r/w) the current motor control tilt angle [degrees]
tiltUse=0 (r/w) should tilt control be attempted (0=not used,
1=used)
led=2 (r/w) LED value: OFF 0, GREEN 1, RED 2, YELLOW 3, B-YELLOW
4, B-GREEN 5, B-RED_YELLOW = 6, B-RED_GREEN = 7
acc=-0.0359 8.2261 -5.053 (r) the current accelerometer reading in N/kg
time=1326194516.8452 (r) Time at last update
accInterval=0.7 (r/w) wait getting acc-readings at least this time [sec]
accRate=0 (r) rate of acc measurements (per second)
accLogN=0 (r/w) log acceleration evert N measurements (0 = close
log)
imageLogN=0 (r/w) log images (color and depth) every Nth imageset (0 =
close log)
replay=0 0 (r) [0]: replay status 1=on, [1] current replay line

The shown values are with the device open, looking a bit down

===Commands===

The available kinect commands are found in the on-line help:
