Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body shape analyzer.

[0002]

2. Description of the Related Art Conventionally, as a body shape analyzer, Japanese Patent Laid-Open No. Sho 62 has been proposed.
The body shape analyzer described in Japanese Patent No. 243535 has been known. The body shape analyzer described in this publication is an imaging device that captures images of the front and side silhouettes of the examinee with an optical camera, and an operator traces the surface of the photograph taken with this imaging device with an digitizer to convert it to an electrical signal. An input device comprising a contour contour extraction means for converting the contour of the examinee, 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, and weight. Calculate the body balance, body fat percentage and obesity degree based on the input data from the input device, compare and calculate these calculated values with the data of a standard healthy person of the same age and the same age as the examinee, and compare these data. And a processor for calculating the body index of the examinee.

[0003]

However, in the method described in the above publication, although the operator usually traces the surface of the photograph such as the silhouette of the front and side taken by the operator with a digitizer, it is converted into an electric signal. Since the contour tracing of the body shape of the examinee differs depending on the patient, there is a problem that an accurate contour cannot be extracted and the operator's burden is heavy for performing the tracing operation. In addition, there is a problem that it takes time because an image is taken, developed, and then converted into an electric signal by a digitizer or the like. Therefore, an object of the present invention is to provide a body shape analyzer which analyzes a body shape easily, quickly and accurately.

[0004]

The present invention has been made to solve the above problems and achieve the above objects.
An imaging device that captures the image of the examinee with an electronic camera from the front or side of the examinee, an input device that inputs data such as the gender, age, height, weight, etc. of the examinee, and data input from this input device The data of the standard healthy person of the same age and the same age of the examinee is taken out from the recorded data from the record data, and the contour line is automatically extracted from the data of the standard healthy person and the image of the examinee photographed by the photographing device to obtain the contour line. It comprises an arithmetic processing unit for calculating the physical balance of the examinee and comparing the calculated data, and an output unit for outputting the compared data.

In the present invention, the electronic camera is a device such as a television camera or a video camera which directly outputs an image to a monitor television or stores the image on a magnetic tape. It is not developed.

[0006]

In the body analyzer of the present invention, the examinee is photographed by the electronic camera from the front or side of the examinee. Therefore, the image photographed by the electronic camera can be directly input to the arithmetic processing unit such as a computer or the It is possible to record on a storage medium such as a tape or a floppy disk, and input to the arithmetic processing unit from this storage medium. Therefore, it is not necessary for an operator to input a photograph taken by an optical camera or the like with a digitizer as in the conventional case. Therefore, the contour of the examinee can be accurately input without being deformed by tracing the photograph. Further, since an image taken by a television camera can be directly input, the measurement can be performed extremely quickly, or the image can be stored in a storage medium such as a magnetic tape and can be used for future diagnosis.

When the image thus photographed is directly or through a storage medium such as a magnetic tape and inputted into the arithmetic processing unit, the contour line of the figure is automatically detected from the image inputted by the arithmetic processing unit. Then, the figure balance of the examinee is calculated from the contour line. On the other hand, data such as the sex, age, height, and weight of the examinee is input from the input device. Then,
From the input data, the data of the normal healthy person of the same age and the same age stored in the arithmetic processing unit is extracted from the recorded data.

Then, in this arithmetic processing unit, the calculated body balance is compared with the data of a normal healthy person. The result of this comparison is output by the output device, which diagnoses the health condition of the examinee. Since an arithmetic processing unit such as a computer is used until the image and the data of the examinee are input and output, the result can be obtained extremely quickly.

Reference numeral 5 denotes a monitor television. The monitor television 5 displays the contour lines extracted by the arithmetic processing unit 4 as an image, and the data input from the input unit 3 indicates the standard health of the same-aged and the same age of the examinee. It is for displaying the data of a person or the like. Reference numeral 6 denotes an output device such as a printer, which outputs data comparing the physical balance of the examinee calculated by the arithmetic processing device 4 and the data of the standard healthy person of the same age and the same age of the examinee.

Next, the state in which the examinee is being analyzed by this figure analysis device will be described. First, the examinee stands in front of the background 1 and photographs with the photographing device 2 from the front and the side. When shooting, it is convenient to watch while watching the monitor TV 5. The image photographed by the photographing device 2 is directly input to the arithmetic processing device 4 or recorded in a storage medium such as a magnetic tape or a floppy desk, and then input into the arithmetic processing device 4 from this storage medium.

Then, this data is stored in the arithmetic processing unit 4 as A
It is converted by the / D conversion unit, the contour of the examinee is extracted by the image memory unit, and the figure balance is calculated. There are various methods for extracting the contour, but a general image processing method such as a combination of binarization processing and boundary tracking processing or edge extraction processing can be used. On the other hand, the input device 3 inputs the sex, age, height, weight, etc. of the examinee. Then, the data of the standard healthy person of the same age and the same age as the examinee recorded in the arithmetic processing unit 4 is taken out, and the data of the standard healthy person and the body balance data calculated by the arithmetic processing unit 4 are taken out. And are compared.

Then, the compared data is output from the output device 6. At this time, if there is no data of the same height as the examinee in the recorded data, it is advisable to compare the standard body shape close to this height by enlarging or reducing it so that the heights match. For comparison, the body shape data of the diagnostician and the data of the normal healthy person are monitored separately.
May be output, or both may be output in an overlapping manner. In any case, it should be easy for the examinee to understand. Also, the compared data can be shown immediately or can be stored and shown in the future. Alternatively, past data may be stored, and the stored past data and current data may be compared and output.
