When you change the settings.xml file and you want to run the contours searching process again, it is not
necessary to terminate the “auto_calib” application. Press the “F5” key to update the settings. If you
change the scale factor at this step of the calibration, it is not going to be updated. The scale factor is
updated only for the second step (fisheye distortion removal). If you want to update the scale factor in
the third step, press the “left arrow” key and return to the second step.
CAUTION
If you use OpenCV3.2 with OpenVX and you see the terminal message
shown in Figure 18, disable the OpenVX version using the “export
NO_OPENVX=1” command in the terminal.

dots. If you want to change the mesh density or height, change the <grid> parameters in the settings.xml
file according to the Surround View Application Reference Manual [1] and press the “F5” key to
recalculate the meshes. Figure 19 shows the actual state of the screen and the terminal screenshot.
