Note on setting the measuring unit

You can take simple measurements in uEye Demo. Before you start measuring, the camera has to be calibrated to a scale. The []/pixel unit indicates the actual distance that corresponds to one pixel. To set the measuring unit, do the following:

1.Mount the camera on a stand. Place an object of known size below the camera (e.g. a ruler).
2.Make sure that the measuring unit is set to 1 at first. Then draw a dimension line over a known distance. The longer you make the dimension line, the higher the measurement accuracy will be.
3.The dimension line will show the length in pixels. Divide the actual distance by the number of pixels measured. Enter this value in the “Set measuring unit” field of the dialog box.

 

Example: Actual distance = 10 cm. Measured length in pixels = 200. Measuring unit = 10 cm / 200 or 100 mm / 200
