REMOTE VISUAL INSPECTION GUIDANCE

A method for guiding a remote visual inspection device along an inspection path defined by a pre-stored inspection path-defining image group, from a current position to a target position, includes capturing the live image feed from the remote visual inspection device from the current position during an inspection of an object; matching features of the live captured image to image features in the pre-stored inspection path-defining image group; identifying a key-frame image which is the next closest image in the path-defining image group corresponding to the target position; estimating a transform between the live captured image and next key-frame image, using a transformation estimation method; and generating guidance instructions, based on the transform, and outputting the guidance instructions to enable the device to be moved along the inspection path to the target position.
