Navigation technique for detecting movement of navigation sensors relative to an object

摘要: A scanning device and method for forming a scanned electronic image include using navigation information that is acquired along with data, then rectifying the data based upon information. The obtained in frames. differences between consecutive frames are detected accumulated, this accumulated displacement value representative of position relative to reference. positioned-tagged from value. To avoid accumulation errors, updated by comparing current frame much earlier stored memory resulting difference as frame. These larger steps determine device.
