To scan using an SX10

1. Tap and select Measure / Scanning.

2. Select the required Scan density.

   To check the point spacing for the selected scan density, enter the distance to the target in the At distance field. The value shown in the Point spacing field shows the point spacing at the specified distance.

   Only the Telecamera is coaxial with the telescope. For accurate framing at close range, enter the approximate distance from the instrument to the object being scanned in the At distance field and then define the scan frame. Entering the correct distance ensures the scan frame is drawn in the correct position by correcting for the offset between the Overview or Primary camera and the telescope.

3. To select the area inside the video window that needs to be captured, select the framing method and then define the frame area.You can scan a full 360° horizontally and vertically down to 148° (164 gon).

   Framing method	To define the frame area...
   Rectangle	Tap on the video screen to define the first corner and then the diagonally opposite corner of the scan rectangle. Tap Complementary frame to select the horizontal complement to the currently defined frame. For example, if you define a frame that is 90°, tap Complementary frame to select the area that is 270°.
   Polygon	Tap on the video screen to define each vertex of the polygon scan area.
   Horizontal band	Tap on the video screen to define the vertical edges of the full 360° horizontal band. Do one of the following: To define the upper limit of a band down to 148°, tap on the video screen above 90° VA. To define the lower limit of a band up to the zenith, tap on the video screen below 90° VA. To switch between the upper and lower selection, Tap Zenith or Nadir. Tap again in the video screen to limit the upper or lower vertical edge of the horizontal band you have defined.
   Full dome	No frame definition is required. The full dome always scans a full 360° horizontally and vertically down to 148° (164 gon).

   When the scan frame is filled it is an acceptable frame; if the scan frame is hollow then the closing line is crossing another line which must be rectified before you are able to start the scan.

   When defining the frame area, tap Undo to remove the last created frame point, or tap Reset region to clear the framing region and start again.

   The software uses the defined frame area to calculate the Number of points and Estimated time required to complete the scan.

   The time to complete a scan is an estimate only. Actual scan times will vary depending on the surface or object being scanned.

4. To capture a panorama image with the scan, select the Panorama check box and specify the panorama settings.

   The software automatically checks the tilt of the instrument during scanning.

5. To change the tilt tolerance, tap Options and then enter a new value in the Tilt tolerance field.

   If the compensator is disabled, the value entered in the Tilt tolerance field is ignored.

6. Tap Start.

   The software shows the progress of the scan. When the scan is complete, the instrument returns to its original position.

To cancel a scan that is in progress, tap Esc and then select whether to save or delete the scan. The scanning record and associated RWCX file will still be written if you manually cancel a scan.
