WiseImage - User's Guide If it is necessary, then add grid columns in the negative direction of the X or Y axis by specifying a negative value for the X or Y size. 5. Specify numbers of grid cells along the X and Y axis using X Cell and Y Cell, accordingly. 6. To prevent mistakes, choose the Preview button to view the grid defined. Correct any mistakes if necessary. 7. Choose OK to create calibration grid and return to the Calibrate dialog box. 8. It is possible to construct a rectangular grid rotated by the defined angle. Otherwise, the grid rows and columns will be orthogonal to the X and Y axis. Adding calibration pairs one by one This method creates calibration pairs one by one. The created pairs may be of the Control, Check, or Unused type. The procedure is designed so that pairs can be created by indicating only the real point coordinates. The measured point coordinates can be entered later. To add calibration pairs one by one 1. Open the Calibration dialog box. 2. Click the button in the dialog window. The following dialog box appears: Add Point dialog box 3. Type the real point coordinates in Real. 4. Type the name for the pair in Label. Otherwise the default name of this pair is "PointNN". 5. Type the measured points' coordinates in Measured or pick the measured point coordinates in the screen by button. Otherwise their coordinates will be equal to the real ones and can be modified later. 6. If necessary, then change the pair type in Use as from Control to Check or define the pair as Unused. 7. Press ENTER or choose Add to create the pair and continue the process. 60
