no. 1 approach

[0045] First, a first embodiment of the present invention will be described. figure 1 The appearance of the endoscope apparatus of this embodiment is shown. figure 2 The functional structure of the endoscope apparatus of this embodiment is shown. image 3 The functional structure of the control unit included in the endoscope apparatus according to this embodiment is shown.

[0046] The endoscope apparatus 1 according to this embodiment is used to take an image of a subject to be inspected, that is, an object to be inspected, and to perform measurement using the image. , or appropriately add measurement programs to enable various observations and measurements. Next, as an example of measurement, a case where stereo measurement is performed will be described.

[0047] Such as figure 1 and figure 2 As shown, an endoscope device 1 includes an optical adapter 2 for stereo measurement, an endoscope insertion unit 3, an endoscope unit 7, a CCU 9 (camera control unit), a liqu...

no. 2 approach

[0115] Next, a second embodiment of the present invention will be described. The endoscope device of the first embodiment captures images including two subject images simultaneously formed by two optical systems, but the endoscope device of the second embodiment captures images each including time-series imaging by two optical systems image of the two subjects.

[0116] In this embodiment, an optical adapter capable of switching the optical path of light incident on the imaging element is attached to the tip of the endoscope insertion portion 3 instead of the stereo measurement optical adapter 2 in the first embodiment. Figure 9 The structure of the optical adapter in this embodiment is shown. An optical adapter 21 is attached to the distal end of the endoscope insertion portion 3 . The optical adapter 21 has concave lenses 23 a , 23 b , convex lenses 24 a , 24 b , a switching unit 25 , and an imaging optical system 26 . An imaging element 3 a is arranged in the front end ...

no. 3 approach

[0146] Next, a third embodiment of the present invention will be described. In this embodiment, a case where a recorded image is reproduced to perform measurement will be described. Next, a method of making the user confirm the image used for the measurement will be described by taking the case where the measurement is performed on the personal computer 17 as an example.

[0147] For example, a file including all image information used for measurement is recorded in the personal computer 17 by the processing of ST109 (image information recording processing). At this time, information representing image information (hereinafter referred to as representative image information) that is representative of all recorded image information is also recorded in the file. In the process of ST109, the file may be recorded on an external storage medium such as a card medium connected to the endoscope apparatus 1, and the external storage medium may be connected to the personal computer 17,...

Abstract

Provided are an endoscope device and a measurement method that allow a user to easily confirm the accuracy of a measurement result while maintaining the visibility of an image. An image generating unit (30) generates an image including one or more subject images. A display unit (33) displays images. The control unit (43) executes: a first process of displaying a moving image including one subject image on the display unit (33); a second process of making all the multiple subjects used in the measurement A body image, or all of a plurality of images based on one subject image used in the measurement is displayed as a still image on the display portion (33); and a third process of specifying a measurement point according to an instruction of a user after the second process, The size of the subject at the designated measurement point is measured from images based on all the plurality of subject images, or from all the plurality of images based on one subject image.

Description

technical field [0001] The invention relates to an endoscope device with measuring function and a measuring method. Background technique [0002] Industrial endoscopes are widely used to observe internal damage and corrosion in the inspection of boilers, turbines, engines, and chemical equipment. In industrial endoscopes, various types of optical adapters are prepared in order to enable observation and inspection of various objects to be observed, so that the tip portion of the endoscope can be replaced. [0003] As one of the optical adapters described above, there is an optical adapter for stereo measurement having two optical systems for forming two left and right subject images corresponding to different viewpoints. Japanese Unexamined Patent Application Publication No. 2005-348870 describes an endoscope device that realizes three-dimensional measurement by stereo measurement using a triangulation principle using an optical adapter for stereo measurement. [0004] The ...
