Verifying the Output of Extrinsic Calibration

Verifying the Output of Extrinsic Calibration

Hello, 

The output of the Position of the camera with regard to world coordinate frame gave me X: 0.62… Y: -1.09… Z:0.02…. This values concerns me because my camera is static at the top facing the leds around 1,49 m away.

During the consistency check when entering the measurement, its says that my measurements are okay. Is there another way for me to verify the output of world to camera transformation matrix?

Related questions:
1. would my matrix value correct despite the output of position in Y axis almost 40 cm away from my entered value?

2. this tool has a problem when detecting my LEDs at 150hz and 200hz. So i edited the algorithm to detect my leds at the frequency that was previewed on the screen. Does this affects my extrinsic parameters?

3. the ground plane calibration Y axis is actually Z axis for my own perspective. Does this mean that the 2nd row of rotation and translation matrix should be swapped with the 3rd row?

Thank you
