Abstract
A system for measuring a hole includes a hole measuring device, processor(s) and a memory. The hole measuring device includes an end portion and an imaging portion. The end portion is configured to be inserted in a hole and includes at least first and second outer contact surface portions configured to be biased against the inner surface of the hole such that a contact distance between the first and second outer contact surface portions varies depending on the diameter of the hole. The end portion includes one or more reference surface portions (e.g., which are each configured to move when a corresponding outer contact surface portion moves). The imaging portion acquires an image of the one or more reference surface portions. The acquired image is used to determine relative positions of the one or more reference surface portions, which in turn are used to determine the diameter of the hole.
