Kinect Depth Map Calibrated

Calibrated the Kinect Depth Sensor.

Picked the depth value of the mid point of depth map. Measured with A4 paper whose length is 279mm.
Data collected as below:

1674:A4*6-1661
1395:A4*5-1382
1116:A4*4-1111
837:A4*3-836
558-A4*2-NULL


In each row the first number is the actual length of the string of paper; 6/5/4/3 is the number of paper; the last number after "-" is the value is abstracted from Kinect Depth Sensor's return value. The value returned should right switch 3 digits(these 3 digits contain the index information).


So the sensor works pretty well in detecting the distance from the object. Especially between 800 to 1100, the error is limited within 5mm. That is the best area for Kinect to detect.
