Why do the Stereo Camera position not correspond with the "TranslationofCamera2" values ?

The calibrator app calibrates the stereo camera and output the extrinsic visualization as follows:
Which is very close to my real setup. As you can see from the image. The second camera translation can be approximated at [50 -11 -2]. Whereas the value that shows in my StereoParams object is "stereoParams.TranslationOfCamera2 = [-51.45 0.68 9.81]". Why is there the negative in X axis and other values? This does not make sense. Could anyone help me with this?

The values that you are comparing are of different context in meaning and does not correspond to each other. The values you see in the figure are the co-ordinates of the selected point in camera 2. Where as, TranslationOfCamera2 is the translation of camera 2 relative to camera 1 in world units. The negative X value denotes the translation of camera 2 to the right of camera 1 (from the viewer's perspective).
