Automated borescope measurement tip accuracy test

摘要

Measurement accuracy of a remote visual inspection (RVI) system is tested using a test object including a test feature having a known geometric characteristic. Using a controller, attachment of a detachable measurement optical tip to an RVI probe is detected. A user is then prompted to perform testing of the measurement accuracy. When the user indicates the test feature is visible, the system captures one or more images of the test feature, determines coordinates of the test feature from the images, and measures a geometric characteristic of the test feature using the coordinates. An accuracy result is determined using the measured geometric characteristic and the known geometric characteristic, and an indication is provided, e.g., to the user, of the result of the comparison. An RVI system with a user-prompt device is also described.

主权项

1. A method of testing measurement accuracy of a remote visual inspection system, the testing using a test object including a test feature having a known geometric characteristic, the method comprising automatically performing the following steps using a controller:
detecting attachment of a detachable measurement optical tip to a probe of the remote visual inspection system; after detecting attachment of the detachable measurement optical tip, prompting a user via a user-prompt device to perform testing of the measurement accuracy of the remote visual inspection system; capturing one or more images of the test feature on the test object; determining coordinates of the test feature using at least some of the captured images; determining a measured geometric characteristic of the test feature using the determined coordinates of the test feature; determining an accuracy result using the measured geometric characteristic and the known geometric characteristic; and providing an indication of the determined accuracy result.
