Abstract

Provided is an endoscope insertion shape analyzing system which is characterized by comprising an insertion shape detection unit that detects an insertion shape of an insertion portion based on coordinate values of a plurality of locations of the insertion portion of an endoscope inserted in an examinee, an insertion shape dividing unit that generates a line segment according to the insertion shape and sets a plurality of dividing points on the line segment and an insertion stop point estimation unit that detects whether or not insertion operation is performed on the insertion portion based on a moving speed on a proximal end side of the insertion portion and detects one dividing point out of the plurality of dividing points where a coordinate value on a predetermined coordinate axis locally becomes maximum and a transmission rate of the moving speed that varies according to the insertion operation is less than a predetermined threshold.

Description

[0001] This application is a divisional application, the application number of the original application is 200780041577.5, the international application number is PCT / 2007 / 063882, the application date is July 12, 2007, and the invention name is "endoscope insertion shape analysis system and living body observation system ". technical field [0002] The present invention relates to an endoscope insertion shape analysis system and a living body observation system, and more particularly, to an endoscope insertion shape analysis system and a living body observation system capable of acquiring information for assisting an insertion operation of an insertion portion of an endoscope. Background technique [0003] Endoscopes have conventionally been widely used in the medical field, industrial field, and the like. In addition, the endoscope is used, for example, in the medical field for observation and various treatments of living tissue and the like. [0004] In particular, when t...
