Abstract
PURPOSE: To improve the measuring accuracy by using image pickup means having adjustable focal length.
CONSTITUTION: A processing circuit 8 for operationally processing the video signals from a monitor 5 to calculate the size of an object 1 to be measured is made to have additional functions such as the function for producing zoom signals Sg and the function for storing operation. And, a zoom lens 7 is set at its first focal length f1 by the first zoom signals Sg1 of the circuit 8 so that the object 1 is taken by a camera 2. The image sizes b1 and b2 of the image 1a obtained in the monitor 5 with respect to the camera axis c are measured and stored for a while. Then, the zoom lens 7 is moved to its second focal point f2 in response to second zoom signals Sg2 so that the object 1 is taken again to store the sizes. After that, the preset calculations are performed on the basis of the stored values. Thus, the sizes can be accurately obtained irrespective of the vibrations and inclinations of the object 1.
