The workpiece to obtain accurate measurement by image measuring instrument is the most basic requirements,methods to measure the use of image measuring instrument which is the key to obtain the request, precisionmeasurement. Image measuring instrument is a high precision measuring instruments, in the process of measurement, the measurement error can lead to a failure.Therefore, measurement strategy measurement personnelneed to follow the image measuring instrument used to measure, including:

1 select the appropriate method of workpiece.

2 select the appropriate work direction.

According to the characteristics of the 3 tested, lightingdesign method of workpiece.

4 in the coordinate system defined workpiece reference(according to the drawings to determine the workpiececoordinate system).

5 to determine the appropriate rate (imaging instrument,no automatic zoom system the need for image calibration).

6 methods for determining the accurate measurement andmeasuring path.

7 image measuring instrument programming.

The 8 recorded information.

The measuring staff experience in the manufacture ofmeasuring the future process of accumulation, canmeasure various workpiece precision and fast!
