[0025] Embodiment 1

[0026] figure 1 It is an overall block diagram of the imaging device according to Embodiment 1 of the present invention. In addition, figure 2 It specifically shows that in the imaging device of Embodiment 1 of the present invention figure 1 Block diagram of the illumination structure.

[0027] First, refer to the following image 3 Description of characteristics figure 1 , figure 2 . in figure 1 In the microscope box 100, a three-dimensional measurement light source 40 for irradiating the subject 1, a normal light source 2, an objective lens 30, and an illumination dichroic mirror 3 are provided below the main dichroic mirror 7.

[0028] In addition, in normal visual observation, the light image of the subject 1 obtained by the epi-illumination from the normal light source 2 passes through the left eyepiece dichroic mirror 6 and the right eyepiece dichroic mirror 8 in the left eyepiece 4 and The image is formed in the right eyepiece section 5. On the other...

[0061] Picture 9 It is an overall block diagram of an imaging device according to Embodiment 2 of the present invention. In addition, Picture 10 It specifically shows that in the imaging device of Embodiment 2 of the present invention Picture 9 Block diagram of the illumination structure.

[0062] First, refer to the aforementioned image 3 Description of characteristics Picture 9 with Picture 10 . in Picture 9 In the microscope box 100, a light source 55 for three-dimensional measurement that irradiates the subject 1, an objective lens 30, and a dichroic mirror 3 for illumination are provided below the main dichroic mirror 7. In addition, the light source 55 for three-dimensional measurement is also used in normal visual observation.

[0063] The light source 55 for three-dimensional measurement in the normal observation mode operates as an epi-illumination in a wavelength band of approximately 300 to 700 nm of visible light. The light source irradiate...

[0091] Picture 12 It is an overall block diagram of an imaging device according to Embodiment 3 of the present invention. First, refer to the aforementioned image 3 Description of characteristics Picture 12 . in Picture 12 In the microscope box 100, a three-dimensional measurement light source 40 that irradiates the subject 1, a normal light source 80 containing excitation light, an objective lens 30, and an illumination dichroic mirror 3 are provided below the main dichroic mirror 7. .

[0092] In addition, in normal visual observation, the optical image of the subject 1 obtained by epi-illumination from the normal light source 80 containing excitation light passes through the left-use naked-eye dichroic mirror 6 and the right-use naked-eye dichroic mirror 8 on the left. Images are formed in the eyepiece 4 and the right eyepiece 5. On the other hand, the imaging optical axis is reflected by the main dichroic mirror 7 and then split by the imaging sp...

Abstract

Provided is image information for appropriately verifying and ascertaining a shape and state of a surface and an interior of a photographic subject which is an operation object. An image capture device comprises: light source units (2, 40) further comprising light sources which have wavelengths of a plurality of bands; an image capture unit (15) which electrically converts a measured light source optical image of a plurality of bands from the light source units which is reflected with a surface and an interior of a photographic subject into a plurality of measured image capture signals; computation units (13, 16, 19) which, on the basis of the plurality of measured image capture signals which are converted with the image capture unit, measure a shape of the surface and a shape of the interior of the photographic subject; and a composite processing unit (19) which composite processes the shape of the surface and the shape of the interior which are measured with the computation units, and generates either two-dimensional image data or three-dimensional image data relating to the photographic subject.

Description

technical field [0001] The present invention belongs to the field of medical cameras used in surgery, and relates to an imaging device and an imaging method for three-dimensional image measurement of an imaging object. Background technique [0002] In the three-dimensional measurement device used in medical treatment such as surgery, the prior art uses ultraviolet light, visible light or near-infrared light to measure the three-dimensional position of a specific part of the human body based on imaging information obtained from a plurality of cameras (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Publication No. 3152810 [0004] However, the prior art has the following problems. [0005] According to Patent Document 1, it is suitable for measurement of a specific site by using a special probe. Therefore, it is not suitable for measuring a certain range related to the surgical site. In addition, three-dimensional information as a meas...
