Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body type diagnostic device.
More specifically, the present invention relates to a body type diagnosing device for diagnosing a spine.

[0002]

2. Description of the Related Art Conventionally, as a body type diagnostic apparatus, Japanese Patent Laid-Open No. 62-62
The body shape diagnosis device described in Japanese Patent No. 243535 has been known. The physical examination apparatus described in this publication uses a photographing means for photographing an image of a front silhouette and a side silhouette of a examinee with an optical camera, and an operator traces the surface of the photograph photographed by this photographing means to an electric signal by an operator. Contour extraction means for obtaining the contour of the examinee by conversion, input means consisting of a skin fat thickness detecting means for detecting the skin fat thickness of the examinee and an input means for inputting the examinee's sex, age, height, weight, etc. Based on the data input from this input means, the body balance, the body fat percentage, and the obesity degree are calculated, and these calculated values are compared and calculated with the data of a standard healthy person of the same age and the same age as the examinee. And a calculation processing means for calculating the physical index of the examinee from the comparison data.
Moreover, as a lighting for photographing a person, Japanese Patent Publication No. 58-4
As described in Japanese Patent No. 2454, there is known a device in which a person is turned toward an image capturing device and light is emitted from both sides obliquely in front of the image capturing device.

[0003]

However, in the body shape diagnosing device described in the above publication, since the photographed front and side silhouettes are photographed, the spine is not photographed. Also, even if a person stands upright so that the spine can be photographed and the silhouette of the back is photographed, it is still a silhouette, so that the portion of the spine cannot be clearly photographed. Therefore, it cannot be used to diagnose the condition of the spine.

In the photographing apparatus described in the above publication, the person is directed toward the photographing apparatus and the light is irradiated from both diagonally front sides to photograph the person. Therefore, the spine is not photographed and cannot be used for diagnosis of the spine. . In addition, even if a person stands upright backwards and photographs the back surface with this device, the entire body is photographed brightly with the light emitted from both sides so that shadows cannot be formed, so the lines of the spine are not clearly visible. Therefore, it cannot be used to diagnose the condition of the spine. Further, there has been no suitable method for indicating the state of the spine by data. Therefore, an object of the present invention is to provide a body type diagnostic apparatus capable of photographing the examinee's spine with a means that clearly shows it and diagnosing the condition of the spine such as the bending of the spine from the photographed image. Another object of the present invention is to provide a body type diagnosing device capable of showing the state of the spine with data.

[0005]

The present invention has been made to solve the above problems and achieve the above objects.
Extraction means for extracting the contour of the examinee and the line of the spine by superimposing the image photographed by irradiating the examinee with light from the left oblique direction on the back side and the image photographed by radiating light from the oblique direction on the right side, An inference means for inferring a normal spine line in which the spine is not bent from the contour of the examinee extracted by this extraction means, and a normal spine line obtained by this inference means and a spine line extracted by the extraction means And a diagnostic means for diagnosing the state of the spine by comparison.

As the extraction means in the present invention, the operator may extract the photographed picture with a digitizer or the like, but it is convenient to use a computer or the like for extraction. In particular, when the photographing means is an electronic camera, and the extracting means is a extracting means for extracting with a computer, the image data obtained by the electronic camera can be directly input to the extracting means or stored in a storage medium and stored at a later date. Since it is possible to input to the extraction means from this storage medium, it is convenient. Here, the electronic camera is a camera such as a television camera or a video camera, which sends an image directly to an extracting means such as a computer, outputs it to a monitor television, or stores it in a storage medium such as a magnetic tape. Thus, the image is not developed on paper or the like like an ordinary optical camera.

The inference means in the present invention is means for inferring a normal line of the spine when the spine is not bent from a photographed image, and there are various means. For example, it may be inferred by looking at a display device such as a cathode ray tube, or may be inferred by being calculated by a computer or the like. Among these, if a suitable inference means is introduced, the left and right lines from the shoulder to the waist of the outline of the examinee extracted by the extraction means are divided into a plurality of lines, and the divided respective points are connected to each other to connect the lines. There is an inference means for inferring the line connecting the center points of the lines as the line of a normal spine in which the spine is not bent. Introducing another suitable inference means, the line connecting the center point between the scapulae of the contour extracted by the extraction means and the center point of the contour line of the waist is taken as a normal spine line in which the spine is not bent. There is an inference means to infer.

In the present invention, the diagnostic means is a diagnostic means for diagnosing the condition of the spine by comparing the line of the spine of the diagnostician extracted by the extracting means with the line of the normal spine inferred by the inference means, There are various means. For example, the state of the spine may be diagnosed by displaying it as an image on a suitable display device such as a cathode ray tube or a liquid crystal display device as illustrated. However, it is convenient to compare with other people and past data if it is indicated by numerical values for diagnosis. Introducing a suitable means indicated by this numerical value, multiple distances between the line of the spine of the diagnostician extracted by the extraction means and the line of the normal spine inferred by the inference means are obtained, and the value, distribution, and change amount are calculated. There is a diagnostic means for diagnosing the condition of the spine of the examinee from the maximum value, the average value and the like.
In addition, if another suitable means is introduced, a plurality of angles formed by the line of the normal spine inferred by the inference means and the line of the spine of the examinee extracted by the extraction means are obtained, and the value, distribution, change amount, There is a diagnostic means for diagnosing the condition of the spine of the examinee from the maximum value, the average value and the like.

[0009]

The operation of the present invention will be described in the order of diagnosis. First, in the physical examination apparatus of the present invention, the image taken by irradiating the back surface of the examinee with light from the left oblique direction and the image taken by irradiating light with the oblique direction on the right side are overlapped, so that the line of the spine of the examinee is overlapped. You can clearly shoot. The reason is that when the back surface of the examinee is irradiated with light obliquely from the left side, the shadow of the convex portion on the back surface clearly appears on the right side. When the back surface of the examinee is irradiated with light obliquely from the right side, the shadow of the convex portion on the back surface clearly appears on the left side. Therefore, by superimposing these two images, the line of the spine appears clearly.

Since the lines of the spine appear clearly by superimposing the images taken by irradiating light from the right and left diagonal directions in this way, the lines of the spine can be accurately and easily extracted by an extracting means such as a computer. it can. Further, the contour of the examinee is extracted by this extracting means. If the extraction means is such that an electronic camera takes a picture of these images and the extraction means is a computer, the data of the image taken by the electronic camera can be directly input, so the contours of the examinee and the line of the spine are extremely fast. It can be extracted or stored in a storage medium such as a magnetic tape and can be used for future diagnosis.

Next, the line of a normal spine in which the spine is not bent is inferred by the inference means from the contour thus extracted. This operation can be easily and automatically inferred by using a computer or the like. As this inference means, the left and right lines from the shoulder to the waist of the outline of the examinee extracted by the extraction means are divided into a plurality of parts, and the divided opposing points are connected to each other to connect the center points of the connected lines. If a line is used as an inference means for inferring a line as a normal line in which the spine is not bent, a computer or the like can automatically and accurately infer it. As this inference means, the line connecting the center point between the scapulae of the contour of the examinee extracted by the extraction means and the center point of the contour line of the waist is inferred as a normal spine line in which the spine is not bent. When the inference means is used, similarly to the inference means for dividing the contour line described above, it is possible to infer accurately and accurately automatically by a computer or the like.

Next, the normal spine line thus inferred is compared with the actual spine line extracted by the extracting means to diagnose the state of the spine by the diagnosing means. This diagnosis means may be shown in the figure or imaged on a video device or the like, but it is convenient to make a diagnosis with appropriate data because it can be compared with other people's data or past data. As a suitable diagnostic means for diagnosing the condition of the spine from the data, a plurality of distances between the line of the normal spine inferred by the inference means and the line of the spine of the examinee extracted by the extraction means are obtained, and its value and distribution There is a diagnostic means for diagnosing the state of the spine of the examinee from the change amount, the maximum value, the average value and the like. In this way, data can be obtained automatically and accurately by a computer or the like, and diagnosis can be performed quickly from these data.

Further, as another preferable diagnostic means for diagnosing the condition of the spine from the data, a plurality of angles formed by the line of the normal spine inferred by the inference means and the line of the spine of the examinee extracted by the extraction means. There is a means for obtaining and diagnosing the condition of the spine of the examinee from this value, distribution, amount of change, maximum value, average value and the like. By doing so, similar to the method of obtaining a plurality of distances described above, data can be obtained automatically and accurately by a computer or the like, and the state of the spine can be accurately and quickly diagnosed from these data. At this time, a plurality of distances and angles of this separation are obtained, but as a method of obtaining the plurality of distances, the accuracy can be improved by dividing the equidistant distance or finely dividing the distance. In this way, if the computer performs everything from photographing to diagnostic means, the results can be obtained extremely quickly and accurately.
