Abstract:
A system for determining a dimension of a feature, the system comprising:a) an optical scope for gathering an image of the feature, the optical scope includingi) a focusing device for adjusting a focal position of the image of the feature,ii) a device for detecting a position of the focusing device and for providing a focus position signal based on the position of the focusing device, andiii) an image-to-video converter for producing a video signal of the feature from the image of the feature having its focal position adjusted by the focusing device;b) an image scaling device for providing a scaled image size; andc) a processor, the processori) converting the focus position signal into at least one of an object distance signal and a magnification signal, andii) determining the dimension of the feature based on the scaled image size and based on the at least one of the object distance signal and the magnification signal, wherein the dimension of the feature includes at least one of a depth and height of the feature.
