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 disclosed in Japanese Patent Laid-Open No. 62-243535 discloses a photographing device for photographing an image of a front silhouette and a side silhouette of a person to be measured such as a medical examinee with an optical camera and a photograph taken by this photographing device. The operator traces the surface with a digitizer and converts it into an electric signal to obtain the contour of the examinee.The contour extraction means and the skin fat thickness detecting means for detecting the skin fat thickness of the examinee and the sex, age, height and weight of the examinee are input. An input device consisting of an input means and a body balance, a body fat percentage, and an obesity degree are calculated based on the input data from the input device, and these calculated values are data of a standard healthy person of the same age and the same age as the examinee. And a calculation processing device that calculates the body index of the examinee from these comparison data.

[0003]

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. In addition, in order to obtain sufficient lateral resolution, it becomes necessary to use an extremely high-resolution image pickup device and processing device. For example, when trying to correspond to a height of 2 m so that the head comes in from the toes of the toes, when a 512 × 480 quantized digital image is obtained from the captured image, the resolution in the waist direction (lateral direction) is 4 It is only 0.17 mm, resulting in a large measurement error. Therefore, an object of the present invention is to provide a body shape analyzer capable of photographing a vertically long body with substantially the same accuracy in the vertical and horizontal directions.

[0004]

The present invention has been made to solve the above problems and achieve the above objects.
A photographing device that photographs the person to be measured through a zoom lens,
A drive device that changes the lens magnification of this zoom lens,
An arithmetic processing unit including an image processing unit for analyzing the body shape of the person to be measured from the image of the person measured by the image capturing apparatus, a control unit for controlling the drive unit and the whole, and an output for outputting the result of body shape analysis. It consists of a device.

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. This electronic camera is a camera 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 like a normal optical camera. is there. The body shape analyzer of the present invention is
As described in the above publication, it can be used as a diagnostic device for comparing with data of a standard healthy person or for measuring the degree of obesity, or as a device for analyzing a figure for tailoring clothes, etc. Available.

[0006]

In the body shape analyzer of the present invention, the image of the person to be measured is taken through the zoom lens, so that the necessary portion can be taken with the optimum size by changing the magnification of the zoom lens. For example, when measuring the height, the height of the entire image can be taken, and when the waist is necessary, the image can be taken at a larger size than when the height is measured. Therefore, the accuracy is extremely high, and the accuracy of the entire measurement data can be made almost the same.

EXAMPLES Next, examples of the present invention will be described. Figures 1-3
1 shows an embodiment of the present invention for diagnosing a person to be measured using the figure analyzer, FIG. 1 is a block diagram of the figure analyzer, and FIG. 2 is the height of the person to be measured by the figure analyzer of FIG. 3 is an explanatory view showing an image when measuring the whole body, and FIG. 3 is an explanatory view showing an image when measuring a portion such as a waist length of the measurement subject by the body shape analyzer of FIG.

In FIGS. 1 to 3, 1 is a background of a screen, a surface lighting device having a uniform illuminance, and the like. Reference numeral 2 denotes a photographing device including a television camera for photographing through the zoom lens 21, and the driving device 22 can change the magnification of the zoom lens 21. Reference numeral 3 denotes an input device for inputting data such as the sex, age, height, and weight of the subject, 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. In addition, data of healthy persons of various ages of men and women are recorded in the arithmetic processing unit 4, and a control unit for issuing a command for changing the zoom lens 21 to the drive unit 22 is also included.

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 determine the standard of the same sex and age of the person to be measured. The data of a healthy person are displayed. An output device 6 such as a printer outputs data obtained by comparing the physical balance of the examinee calculated by the arithmetic processing device 4 and the data of a standard healthy person of the same age and the same age as the person to be measured. Reference numeral 7 is an image of the person to be measured.

Next, a state in which the person to be measured is analyzed by this body shape analyzer will be described. First, the person to be measured stands in front of the background 1 and photographs with the photographing device 2 from the front and the side. At this time, the zoom lens 21 is used to take an image of an appropriate size. For example, when it is desired to obtain data of a vertically long image such as height, as shown in FIG.
When it is desired to obtain the data of the image, and to obtain the data of the image that is short in the lateral direction such as the waist, the data is obtained from the image 7 enlarged by increasing the magnification as shown in FIG. Further, it is possible to further expand it when it is desired to obtain partial data. When taking this image, it is convenient to perform it while watching the monitor TV 5.

As described above, when an image is taken, the zoom lens 21 is driven and the image can be taken in the optimum size, so that the vertical and horizontal data can be taken with substantially the same accuracy. The image photographed by the photographing device 2 is directly input to the arithmetic processing device 4 or recorded on a storage medium such as a magnetic tape or a floppy desk, and input from the storage medium into the arithmetic processing device 4.

The input data is converted by the A / D converter in the arithmetic processing unit 4, the contour of the person to be measured is extracted in the image memory, 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, and edge extraction processing is preferably used.

On the other hand, the input device 3 inputs the subject's sex, age, height, weight and the like. Then, the processor 4
The data of the standard healthy person of the same age and the same age as that of the person to be measured, which is recorded in, is taken out, and the data of the standard healthy person is compared with the data of the body balance calculated by the arithmetic processing unit 4. . Then, the compared data is output from the output device 6. At this time, if the recorded data does not include data of the same height as the measurement subject, it is advisable to compare the standard body shape close to this height by enlarging or reducing it so that the heights match.

In the case of comparison, the data of the figure balance of the diagnostician and the data of the standard healthy person may be separately output to the monitor 5, or both may be output in an overlapping manner. In any case, the output should be easy 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 figure analysis apparatus of the present invention photographs through a zoom lens, it is possible to photograph a subject whose length is long and width is short, such as height, with substantially the same vertical and horizontal precision. Therefore, the data of the photographed image can be processed with substantially the same accuracy, which is convenient.
