Description

  The present invention relates to an apparatus for measuring the circumference of a human body, and more particularly to a technique for measuring the circumference of a human body by an optical method.

  A tape measure has been used as a normal method of measuring around the waist and hips of the human body. However, when measuring around the waist or hips of a human body using a tape measure, various external personnel such as how much the measurer applies to the tape measure, whether the subject takes a breath, or exhales As a result, the measurement results changed and the measurement error was very severe.

  Therefore, the present inventor has repeatedly conducted research on a technique that can accurately measure the circumference of the human waist and the hips irrespective of the external environment of the person to be measured and the person to be measured using optical technology. As a part of such research, the human body circumference measuring apparatus according to the present invention was proposed.

  The present invention has been invented for the purpose described above, and an object thereof is to provide a human body circumference measuring apparatus capable of accurately measuring the human body circumference using an optical technique.

  According to an aspect of the present invention for achieving the above object, the human body circumference measuring device according to the present invention photographs an outline image formed around the human body by horizontal light irradiated on the human body, and the photographed human body It is characterized by analyzing information around the human body from the outline image.

  Therefore, the present invention has an advantage that it is possible to accurately measure around the waist and buttocks of the human body almost regardless of the external environment of the measurer or the person to be measured using the optical technique.

  The apparatus for measuring the circumference of a human body according to the present invention can capture an outline image formed around the human body by horizontal light irradiated on the human body, and can analyze information around the human body from the captured outline image of the human body. Therefore, it has a useful effect that it is possible to accurately measure the waist circumference and the hip circumference of the human body almost regardless of the external environment of the measurer or the subject using the optical technique.

  Hereinafter, the present invention will be described in detail so that those skilled in the art can easily understand and reproduce the present invention through preferred embodiments described with reference to the accompanying drawings.

  FIG. 1 is a schematic diagram of an apparatus for measuring around the human body according to the present invention, and FIG. 2 is a perspective view illustrating a configuration of an apparatus for measuring around the human body according to an embodiment of the present invention. As shown in FIG. 1, the measurement apparatus 100 around the human body according to the present invention includes at least one horizontal light irradiation unit 110, at least one photographing unit 120, and a control unit 130.

  At least one horizontal light irradiation unit 110 is provided to irradiate the human body 200 with horizontal light. At this time, the horizontal light irradiation unit 110 may be configured to irradiate light such as visible light or infrared light classified according to the light wavelength. It is desirable that the laser beam (Laser Beam) emitted with light of one wavelength is irradiated. Since the laser beam has optical characteristics such as monochromaticity, coherence, high brightness, directivity, and energy concentration, it forms a clear outline when irradiated to the human body.

  Meanwhile, the horizontal light irradiation unit 110 may be configured to irradiate the human body with horizontal light from a plurality of positions around the human body, thereby minimizing an error due to the position of the human body. It is preferable to provide a plurality of light irradiation units 110 so as to be symmetrical on both sides of the human body. That is, if the human body is irradiated with horizontal light from a plurality of positions around the human body, an outline is formed around the entire human body, and the outline formed around the human body is constant regardless of the position of the human body. The error due to the position of the human body can be minimized when measuring around the human body.

  The photographing unit 120 is provided with at least one height different from that of the horizontal light irradiation unit 110 to photograph an outline of the human body 200 formed by the light emitted from the horizontal light irradiation unit 110. . At this time, the reason why the photographing unit 120 is provided at a height different from that of the horizontal light irradiation unit 110 is to accurately photograph the outline shape formed on the human body. If the photographing unit 120 is provided at the same height as the horizontal light irradiating unit 110, the outline formed on the human body is photographed in a straight line, so the outline shape cannot be determined. It is.

  On the other hand, the photographing unit 120 may use a special camera such as an infrared camera depending on the type of light emitted by the horizontal light irradiation unit 110, but recently adopts a CCD camera that can be easily used. Is desirable. When a laser beam is used as the light irradiated by the horizontal light irradiation unit 110, an image exposed on a solid-state imaging device (CCD: Charged Coupled Device) is transmitted by changing it into an electrical form, thereby achieving a clear image quality. By adopting a CCD camera that can obtain an image, an outline image formed around the human body can be taken at a lower cost than a special camera.

  The controller 130 analyzes information about the outline of the human body from the outline image of the human body 200 photographed by the photographing unit 120. At this time, the information around the outline of the human body analyzed by the controller 130 may be the size around the outline of the human body and the shape around the outline of the human body. From the information around the outline of the human body analyzed by the control unit 130, the measurement site, for example, the circumference of the human body such as the waist and the buttocks can be known.

  For example, the controller 130 can measure the outline of the human body using a software algorithm that measures the length of the closed curve. As an example, the outline image of the human body 200 photographed by the photographing unit 120 is processed by software to extract only the outline portion, and the x and y coordinates of each point constituting the extracted outline are obtained and adjacent to each other. By calculating the x-coordinate difference value and the y-coordinate difference value between the points, the distance between the two adjacent points is known, and by calculating the sum of the distances between the adjacent points, an approximate value around the outline of the human body 200 Can be calculated.

  Accordingly, when the horizontal light irradiation unit 110 irradiates the human body 200 with horizontal light, the human body circumference measuring apparatus 100 according to the present invention forms an outline around the human body in the horizontal direction due to the horizontal light. If the outline image formed on the human body is photographed through the photographing unit 120, the control unit 130 analyzes the surrounding information of the human body from the photographed outline image of the human body so that the size and shape of the human body can be known. Using the optical technique, it is possible to accurately measure around the waist and buttocks of the human body almost regardless of the external environment of the measurer or the subject.

  Referring to FIG. 2, the mechanical configuration according to an embodiment of the measurement apparatus 100 around the human body according to the present invention will be examined. As shown in FIG. 2, the measurement apparatus 100 around the human body according to the present invention includes a lower body 10 that supports the bottom and simultaneously places the human body 200, the horizontal light irradiation unit 110, and the imaging unit 120. And an upper body 20 that can be raised and lowered to adjust its height. The control unit 130 illustrated in FIG. 1 is provided in the form of an IC chip inside the lower body 10 or the upper body 20.

  At this time, the upper body 20 has, for example, a substrate 21 in a form in which one side is opened, such as a donut shape opened on one side, a 'U' shape, and the human body can go in and out of the opened portion, At least one horizontal light irradiation unit 110 provided inside the substrate 21 and at least one photographing unit 120 provided at a different height from the horizontal light irradiation unit 110 inside the substrate 21 are included. On the other hand, the upper body 20 including the substrate 21 having an opening on one side may further include an opening / closing part 22 for opening and closing the opening.

  Therefore, when measuring around the human body 200, the person to be measured enters and exits a portion where the one side of the substrate 21 is opened and puts his / her foot on the lower body 10, for example, a desired measurement site, for example, waist, buttocks. If the height of the upper body 20 is adjusted to such a height and the measurement button 196a is pressed, the human body is irradiated with light from the horizontal light irradiation unit 110 provided inside the substrate 21 of the upper body 20. Next, an outline is formed in the human body by the light applied to the human body, and if an outline image of the human body is photographed through the photographing unit 120 provided inside the substrate 21 of the upper body 20, the control unit 130 performs the photographing. The outline image of the human body can be analyzed to obtain information about the human body such as the size or shape of the human body. Therefore, the present invention uses an optical technique to externally measure a person or a person to be measured. It is possible to accurately measure around the waist and hips of the human body almost regardless of the condition.

  On the other hand, according to the additional aspect of the present invention, the surrounding measuring apparatus 100 according to the present invention may further include a light progress blocking unit 140. The light progress blocking unit 140 blocks the progress of the light irradiated from the horizontal light irradiation unit 110 and passing through the human body 200. That is, in this embodiment, various problems that may occur when the light irradiated from the horizontal light irradiation unit 110 and passed through the human body 200 continues to progress, such as discomfort and other problems. In order to prevent malfunction of the electronic device, the light passing through the human body 200 is absorbed through the light progress blocking unit 140 or irregularly reflected so that the light progress can be blocked. is there.

  For example, as shown in FIG. 2, the light progress blocking unit 140 is provided inside the substrate 21 on the side facing the horizontal light irradiation unit 110 provided inside the substrate 21 of the upper body 20 with respect to the human body. Is desirable. At this time, the light progression blocking unit 140 may be integrated with the inside of the substrate 21 by implementing the inside of the substrate 21 on the side facing the horizontal light irradiation unit 110 as a material that absorbs or diffusely reflects light. . Therefore, the present invention can effectively block the progress of the light irradiated from the horizontal light irradiation unit 110 through the light progress blocking unit 140 and passing through the human body 200.

  On the other hand, according to the additional aspect of the present invention, the measurement apparatus 100 around the human body according to the present invention may further include a transfer unit 150. The transfer unit 150 moves the horizontal light irradiation unit 110 up and down according to a human body condition so that light can be applied to a certain part of the human body. In other words, when measuring around the human body, the human body condition, that is, the height of the person to be measured is different for each person to be measured. The horizontal light irradiation unit 110 must be moved up and down according to human body conditions so that light can be irradiated. The measurement apparatus 100 around the human body according to the present invention moves the horizontal light irradiation unit 110 up and down through the transfer unit 150.

  In the case of FIG. 2, since the horizontal light irradiation unit 110 is provided inside the substrate 21 of the upper body 20, the transfer unit 150 is implemented so that the substrate 21 of the upper body 20 moves up and down with respect to the lower body 10. Accordingly, the horizontal light irradiation unit 110 can be moved up and down. At this time, the transport unit 150 may be transported up and down by a specific distance with reference to a specific part of the human body. For example, if the measurement device 100 around the human body according to the present invention is a device that measures the circumference of the waist, the transfer unit 150 is configured so that the horizontal light irradiation unit 110 is only about a specific interval up and down based on the average waist height of the human body. It may be implemented to limit the transfer of the horizontal light irradiation unit 110 to be transferred.

  Meanwhile, the horizontal light irradiation unit 110 is manually moved up and down by the hand of the measurer or the person being measured, the semi-automatic type in which the horizontal light irradiation unit 110 is automatically moved up and down by a user's button operation, etc. The horizontal light irradiation unit 110 may be automatically moved up and down automatically by a sensor operation without any operation.

  For example, in the case of the manual transfer unit 150, a handle (not shown) is provided at an appropriate position of the upper body 20, and a vertical bar supported by the lower body 10 is provided in the transfer unit 150. If an insertion groove to be inserted into the vertical bar is provided on the substrate 21 and the friction surface between the vertical bar and the insertion groove is embodied to have a friction coefficient capable of resisting gravity, the operator or the subject When the measurer takes the handle by hand and moves the substrate 21 of the upper body 20 up and down, the horizontal light irradiation unit 110 provided inside the substrate 21 of the upper body 20 moves up and down.

  For example, in the case of the semi-automatic transfer unit 150, an adjustment button 196 c is provided at an appropriate position above the substrate 21 of the upper body 20, and if the measurement person or the person to be measured presses this adjustment button 196 c, the motor ( By driving a hydraulic or pneumatic cylinder (not shown) supported by the lower body 10 by driving (not shown), the substrate 21 of the upper body 20 is moved up and down to raise the substrate 21 of the upper body 20. The horizontal light irradiation unit 110 provided inside moves up and down.

  For example, in the case of the automatic transfer unit 150, if the case of measuring the circumference of the waist is taken as an example, the adjustment button is not provided, and the imaging unit 120 operates as a sensor for detecting the waist position, and the imaging unit 120. The control unit 130 detects the measurement subject's umbilicus from the human body image photographed by the control unit in software and drives a motor (not shown) to support the lower body 10 with a hydraulic or pneumatic cylinder. The horizontal light irradiation unit 110 provided inside the substrate 21 of the upper body 20 is moved up and down to the detected umbilical height by compressing or expanding (not shown) the substrate 21 of the upper body 20. Goes up and down.

  On the other hand, according to an additional aspect of the present invention, the human body circumference measuring apparatus 100 according to the present invention may further include a fixing unit 160. The fixing unit 160 simultaneously fixes the horizontal light irradiation unit 110 and the imaging unit 120 so that the relative position between the horizontal light irradiation unit 110 and the imaging unit 120 is always constant. That is, when the relative position of the horizontal light irradiation unit 110 that irradiates light to the human body and the imaging unit 120 that captures the outline image of the human body formed by the light irradiated to the human body is changed, the image is captured at the same magnification. Even the outline image has a different size. If the size of the captured outline image is different even at the same magnification, this results in a measurement error, so the relative position between the horizontal light irradiation unit 110 and the imaging unit 120 is always set. It is important to keep it as well. Accordingly, the measurement apparatus 100 around the human body according to the present invention holds the relative position between the horizontal light irradiation unit 110 and the photographing unit 120 through the fixing unit 160 so as to be always constant.

  For example, the horizontal light irradiation unit 110 and the imaging unit 120 may be fixedly installed inside the substrate 21 of the upper body 20 so that the substrate 21 itself performs the role of the fixing unit 160. Differently, the horizontal light irradiation unit 110 and the fixing unit 160 in which the photographing unit 120 is fixedly installed may be provided inside the substrate 21 of the upper body 20. By doing so, the size of the outline image captured at the same magnification is maintained so that the relative position between the horizontal light irradiation unit 110 and the imaging unit 120 is always constant, and the horizontal light irradiation unit 110 Since the difference does not occur depending on the relative position between the image capturing unit 120 and the photographing unit 120, it is possible to prevent surrounding measurement errors.

  On the other hand, according to the additional aspect of the present invention, the surroundings measuring apparatus 100 according to the present invention may further include a light diffusing unit 170. The light diffusion unit 170 diffuses light emitted from the horizontal light irradiation unit 110 in the horizontal direction to form a slit beam. For example, when the light irradiated to the human body from the horizontal light irradiation unit 110 is a laser beam, the laser beam has energy concentration due to the characteristics of the laser beam. This must be diffused to form a slit beam. Accordingly, the measurement apparatus 100 around the human body according to the present invention diffuses the light emitted from the horizontal light irradiation unit 110 through the light diffusion unit 170 in the horizontal direction to form a slit beam, thereby uniformly distributing light to the human body.
