Definitions

  • An example of such an optical adapter includes an optical adapter for stereo measurement which forms two left and right fields of view in an observation optical system.
  • Japanese Unexamined Patent Publication, First Publication No. 2005-348870 discloses an endoscope apparatus that uses an optical adapter for stereo measurement, calculates three-dimensional spatial coordinates of a subject on the basis of the coordinates of left and right optical system distance calculating points when a subject image is captured by left and right optical systems with parallax using the principle of triangulation, and performs three-dimensional measurement (stereo measurement) of the subject.
  • FIG. 13 is a reference view showing a display screen of the endoscope apparatus in the modified example of the first embodiment of the present invention.
  • FIG. 26 is a flow chart showing the procedure of an operation (play processing) of the endoscope apparatus according to the third embodiment of the present invention.
  • the CPU 10 when performing the second processing for reading the positional relationship information between the imaging device in the tip portion and the object lens system of the optical adapter 2 for stereo measurement, the CPU 10 performs the second processing by acquiring the shape of a mask provided in the optical adapter 2 for stereo measurement and comparing the shape and position of the mask at the time of production. In this case, acquisition of the mask shape is performed by imaging an object for calibration and obtaining a white image.
  • FIG. 4 shows the procedure of the entire operation of the measuring endoscope apparatus 1 .
  • the measuring endoscope apparatus 1 operates in an image display mode in which an image acquired through the optical adapter 2 for stereo measurement is displayed on the liquid crystal monitor 6 .
  • the measuring endoscope apparatus 1 operates in various processing modes corresponding to operation inputs when an operation input occurs from the operation portion, such as the remote controller 5 .
  • modes in which measurement processing, image information recording processing, and image file play processing are performed will be described as examples of various processing modes.
  • the video signal processing portion 34 performs processing for enlarging one parallax image (parallax image 61 L) of the two parallax images divided in ST 110 .
  • a video signal based on a parallax image 61 La after enlarging processing is output as the output video signal 101 A to the signal conversion portion 38 .
  • the video signal processing portion 34 performs enlarging processing on the entire parallax image 61 L to set it as the parallax image 61 La such that the length of the parallax image 61 La after enlarging processing in the longitudinal direction is approximately equal to the length of the screen of the display portion 33 in the longitudinal direction.
  • the entire parallax image 61 L is subjected to enlarging processing up to a region, in which the parallax images 61 L and R were not displayed in the display screen 60 shown in FIG. 5 , and is displayed as the parallax image 61 La.
  • the measurement cursor 66 is for inputting a measuring point on the display screen 60 A in response to an operation input from the operation portion 31 or performs an operation such as selection of an icon or menu.
  • the object distance information shows the degree of the distance between the tip portion of the endoscope insertion portion 3 and the object 62 . This object distance is calculated by the image measurement processing portion 43 . The object distance is expressed by six square indicators, and a smaller number of square indicators are displayed as the object distance becomes smaller.
  • a message that requests a measuring point input is displayed as the message information 67 of FIG. 7 , and the measuring point input is received.
  • the examiner inputs a measuring point by moving the measurement cursor 66 and selecting a position on the screen with the operation portion 31 while observing the display screen 60 A of the display portion 33 .
  • coordinate information on the parallax image 61 L (parallax image 61 La after enlarging processing) is acquired and, for example, X-shaped selected position display FIGS. 69 a and 69 b are displayed so as to overlap the parallax image 61 La after enlarging processing, as shown in FIG. 8 .
  • ST 114 ends when the examiner designates two positions as described above, and the process proceeds to ST 115 .
  • the image measurement processing portion 43 performs measurement processing using the parallax of two images on the basis of the measuring position on the parallax image 61 L input in ST 114 and the corresponding position on the parallax image 61 R corresponding to the measuring position on the parallax image 61 L calculated in ST 115 .
  • control portion 45 may automatically display both the parallax images 61 L and 61 R on the display screen of the display portion 33 so as to enable the examiner to modify the measuring point.
  • ST 120 to ST 124 are added between ST 115 and ST 116 of FIG. 6 .
  • the control portion 45 compares the matching degree calculated by the image measurement processing portion 43 with a threshold value and checks whether or not the matching degree is equal to or more than the predetermined threshold value. When the matching degree is equal to or more than the predetermined threshold value, the process proceeds to ST 116 . When the matching degree is smaller than the predetermined threshold value, a message indicating that there was an error in the image matching processing is displayed on the message information 67 as shown in FIG. 11 , and proceeds to ST 121 .
  • the examiner modifies the measuring point by moving the measurement cursor 66 and selecting a position on the screen with the operation portion 31 while observing the display screen on which both the parallax images 61 L and 61 R are displayed. Corresponding to the modified position, coordinate information on the parallax images 61 L and 61 R are acquired again.
  • the control portion 45 checks whether or not an operation for terminating the input of a measuring point in the operation portion 31 has been performed. When the operation for terminating the input of measurement has not been performed, the process proceeds to ST 114 . In addition, when the operation for terminating the input of a measuring point has been performed, the process proceeds to ST 116 in which measurement processing is performed.
  • the measuring point input in ST 114 may be cleared and a measuring point may be input again in ST 122 .
  • the visibility can be further improved by enlarging one parallax image and displaying it.
  • a video signal of the one-frame input video signal 100 acquired in S 101 is output as the output video signal 101 A to the signal conversion portion 38 without any change. That is, when the operation input does not occur, image data including both the parallax images 61 L and 61 R is displayed on the display portion 33 .
  • Enlarging processing of a parallax image in the second embodiment is different from that in the first embodiment. Although enlarging processing of the entire parallax image 61 L is performed automatically in the first embodiment, enlarging processing of a region of the parallax image 61 L designated by the examiner is performed in the second embodiment.
  • the signal conversion portion 38 superimposes the measurement information 102 , which is generated in the image measurement processing portion 43 , on the output video signal 101 A based on the parallax image 61 L and outputs it to the display portion 33 as the display video signal 101 a .
  • the display portion 33 displays the parallax image 61 L on the basis of the display video signal 101 a.
  • FIG. 17 shows a display screen 60 B at the start of such measurement mode.
  • the parallax image 61 L, the date information 63 , the measurement condition information 64 , the operation icon 65 , the message information 67 , an enlargement cursor 72 , and the like are displayed on the display screen 60 B.
  • the video signal processing portion 34 outputs the input video signal 100 from the video signal acquisition portion 30 , as the output video signal 101 A, to the signal conversion portion 38 without any change. That is, in this modified example, a video signal based on the parallax images 61 L and 61 R is output as the output video signal 101 A to the signal conversion portion 38 . Then, the signal conversion portion 38 superimposes the measurement information 102 , which is generated in the image measurement processing portion 43 , on the output video signal 101 A based on the parallax images 61 L and 61 R and outputs it to the display portion 33 as the display video signal 101 a . The display portion 33 displays the parallax images 61 L and 61 R on the basis of the display video signal 101 a.
  • the parallax image 61 La after enlarging processing is displayed in the approximately middle display region of the display screen 60 F.
  • the date information 63 , the measurement condition information 64 , the operation icon 65 , the message information 67 , and the like are displayed in upper and lower portions of the frame-shaped display region.
  • the measurement cursor 66 is displayed so as to overlap the parallax image 61 La after enlarging processing.
  • the video signal temporarily stored in the image storage portion 42 is output to the video signal processing portion 34 .
  • the video signal processing portion 34 divides acquired image information for every parallax image by performing processing for dividing an image of the video signal from the image storage portion 42 into two parallax images 61 L and 61 R.
  • the signal conversion portion 38 superimposes the measurement information 102 , which is generated in the image measurement processing portion 43 , on the output video signal 101 A based on the parallax image 61 La after enlarging processing and outputs it to the display portion 33 as the display video signal 101 a .
  • a display screen at this time is the same as the display screen 60 A of FIG. 7 except that the display screen is not real-time display but still image display unlike the image display mode. In this case, for example, modifications for displaying the date at the time of recording as the date information 63 or displaying text information for identifying an image file or an icon indicating the image play mode on the display screen 60 so as to overlap the display screen 60 may be suitably performed.
  • the present embodiment relates to storage processing of image information and play processing of an image file, that is, an operation when an operation input for recording image information or an operation input for playing an image file is performed as the operation input in ST 102 of FIG. 4 .
  • a display image and a measurement image are recorded separately from each other.
  • ST 415 to ST 424 show measurement processing in which image measurement is performed using the video signal stored in the image storage portion 42 in ST 411 .
  • an explanation will be made focusing on a different point from the measurement processing of ST 110 to ST 118 of FIG. 6 .
