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 a photographing device for photographing images of the front and side silhouettes of a person to be measured such as a medical examinee with an optical camera, and an operator tracing the surface of the photograph taken by this photographing device with a digitizer. Contour extraction means for converting the electric signal into an electric signal to obtain the contour of the examinee,
An input device consisting of a skin fat thickness detecting means for detecting the skin fat thickness of the examinee and an input means for inputting the sex, age, height and weight of the examinee, and a figure balance and body fat based on the input data from the input device.

However, according to the method described in the above publication, since the body is narrow in the horizontal direction and long in the vertical direction, it is not possible to obtain information with the same accuracy. In particular, this accuracy becomes a problem particularly when shooting with an electronic camera such as a television camera or a video camera. That is,
If information is obtained with the same resolution in the vertical direction and the horizontal direction, the resolution of the system is determined in the vertical direction, and there are many unnecessary portions in the horizontal direction. On the contrary, in order to obtain sufficient resolution in the lateral direction, an extremely high resolution imaging device,
The need to use processing equipment arises. For example, when trying to reach a height of 2 m so that the head goes in from the tip of the toes,
When trying to obtain a 512 × 480 quantized digital image from the captured image, the resolution in the waist direction (lateral direction) is only 4.17 mm, and the measurement error increases. Therefore, the object of the present invention is to provide a body that is long in the vertical direction.
It is an object of the present invention to provide a body shape analyzer capable of capturing images in the vertical direction and the horizontal direction with substantially the same accuracy.

The present invention has been made to solve the above problems and achieve the above objects.
A photographing device for photographing the image of the person to be measured, an arithmetic processing device including an image processing unit for analyzing the body shape from the image of the subject measured by the photographing device, and a control unit for controlling the whole body,
In a body shape analyzer including an output device for outputting the result of body shape analysis, the photographing device is a device for photographing through a cylindrical lens, and the output device is a device for correcting and outputting an image distorted by the cylindrical lens. It is a thing.

In the present invention, the photographing device may be an optical camera, but it is preferable because the image photographed by the electronic camera can be directly processed by the arithmetic processing device. The electronic camera referred to here is one that outputs an image directly to a monitor TV or stores it on a magnetic tape like a TV camera or a video camera, and does not develop the image on paper or the like like an ordinary optical camera. It is a thing. The body shape analyzer of the present invention, as described in the above publication, is used as a diagnostic device for comparing with data of standard healthy people, measuring obesity, or for tailoring clothes and the like. It can be used as a device for analyzing the body shape of

[0006]

In the figure analysis apparatus of the present invention, since the image of the person to be measured is taken through the cylindrical lens, the length of the person to be measured is shortened so that the length and width are substantially the same as the body. You can shoot in size. In this way, since the vertical and horizontal images can be taken with substantially the same size, the data can be processed with the same accuracy.

In particular, in the case of the electronic photographing apparatus, the accuracy can be improved because the image can be processed on the entire screen. Then, in this way, the vertical direction is reduced to perform image processing or the like to perform a figure analysis, and the distorted image is corrected and output. Therefore, the output image is the same as a normal image, and in particular, there is no problem. Absent.

EXAMPLES Next, examples of the present invention will be described. Figures 1-3
1 shows an embodiment for diagnosing a person to be measured using the body shape analyzer of the present invention. FIG. 1 is a block diagram of the body shape analyzer, and FIG. 2 is a person to be imaged by the body shape analyzer of FIG. FIG. 3 is an explanatory view showing an image of FIG. 3, and FIG. 3 is an explanatory view showing an image obtained by correcting the image obtained in FIG.

In FIGS. 1 to 3, reference numeral 1 is a background of a screen, a surface illumination device having a uniform illuminance, and the like. Reference numeral 2 is an image pickup apparatus including a television camera with a cylindrical lens 21. Reference numeral 3 denotes an input device for inputting data such as the sex, age, height, and weight of the examinee, which may be a general-purpose input device such as a keyboard.

Reference numeral 4 denotes an arithmetic processing unit in which an image processing board having a video input / output section is incorporated in a personal computer, and this image processing board is provided with an A / D conversion section and an image memory section. Then, in the arithmetic processing unit 4, data of healthy persons of various ages of men and women is recorded. Reference numeral 5 denotes a monitor television. The monitor television 5 displays the contour line extracted by the arithmetic processing device 4 as an image, and the data input from the input device 3 is used to display a standard healthy person of the same age and the same age as the person to be measured. The data and the like are displayed.

Reference numeral 6 denotes an output device such as a printer, which outputs data obtained by comparing the body balance of the subject calculated by the arithmetic processing unit 4 and the data of a standard healthy person of the same age and the same age as the subject. Alternatively, the distorted image 7 photographed through the cylindrical lens 21 is corrected and output as an image 8 which is substantially equal to the actual image.

Next, a state in which the body shape of the examinee is analyzed by this body shape analyzer will be described. First, the measured person is the background 1
Stand in front of and shoot with the photographing device 2 from the front and the side. When shooting, it is convenient to watch while watching the monitor TV 5. This image is directly input to the arithmetic processing unit 4, or recorded on a storage medium such as a magnetic tape or a floppy disk, and input from the storage medium into the arithmetic processing unit 4. Although the actual body is long in the vertical direction and short in the horizontal direction, the image photographed by the photographing device 2 is a distorted image so that the photographed image 7 is substantially equal in the vertical and horizontal directions as shown in FIG. Therefore, when the image 7 is processed, it can be processed with substantially the same accuracy in the vertical and horizontal directions.

The data of the photographed image 7 is converted in the A / D converter in the arithmetic processing unit 4, the contour of the examinee is extracted in the image memory, and the figure balance is calculated. still,
There are various methods for extracting this 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 subject's sex, age, height, weight, and the like. Then, the data of the standard healthy person of the same age and the same age as the person being measured, which is recorded in the arithmetic processing unit 4, is taken out, and the data of the standard healthy person and the body balance calculated by the arithmetic processing unit 4 are calculated. The data is compared.

Then, the compared data and the image 7 photographed by being distorted by the cylindrical lens of the subject are corrected, and the image 8 is output from the output device 6. If there is no data for a standard healthy person with the same height, and if there is no data for the same height as the person to be measured in the recorded data, the standard body shape close to this height may be enlarged to match the height. It is good to reduce or compare.

In the case of comparison, the body balance data of the person to be measured and the standard healthy person data may be separately output to the monitor 5, 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.

[0016]

Since the body analysis apparatus of the present invention photographs through a cylindrical lens, it is possible to photograph a subject such as a body that is long in the vertical direction and short in the horizontal direction with substantially the same accuracy in the vertical and horizontal directions. This is convenient because it can process captured image data with almost the same accuracy. Then, when an image distorted by this cylindrical lens is output, there is no problem because it is corrected.
