〔overall structure〕
As shown in FIG. 1, the apparatus includes an imaging apparatus A that captures an image of the person H to be measured and obtains an imaging angle and an imaging distance at the time of imaging, and the person to be measured from the captured image information captured by the imaging apparatus A. A body size measurement system is configured including an information processing apparatus B that acquires the size of each part of the body of H.

  As shown in the figure, this body size measuring system sets a photographing device A on a tripod 3 and performs photographing in a studio environment in which a screen-like background 1 for photographing and a lighting device 2 are set. However, the dedicated background 1 and the illumination device 2 are not necessarily required. For example, an indoor wall surface (planar object) may be used as the background 1 and a camera strobe may be used as the illumination.

  As the background 1, it is preferable to use a retroreflective sheet in order to clarify the outline of the body image information included in the photographed image information, and the tripod 3 is not necessarily used for photographing. A may be taken by holding A.

  In particular, when photographing with the photographing apparatus A, it is desirable to arrange the person H to be measured at the center of the photographing area. For example, a rectangular frame indicating an ideal photographing area with respect to the finder or the live view monitor of the photographing apparatus A And the composition at the time of shooting may be determined so that the person to be measured H is included in this frame.

  In the figure, the communication cable 4 for transmitting information from the photographing apparatus A to the information processing apparatus B is shown. However, in order to transmit the information, a communication technique such as a wireless LAN or Bluetooth (registered trademark) is used. Also good. Further, in order to pass information from the photographing apparatus A to the information processing apparatus B, a medium M such as a flash memory used for photographing by the photographing apparatus A may be used. In this case, an operation for artificially setting the medium M in the drive of the information processing apparatus B is required.

  In this measurement system, after the operator has photographed only the background 1 with the photographing apparatus A, the person H to be measured stands in front of the background 1, and the photographing apparatus A photographs the front and the side. By performing this imaging, the imaging apparatus A extracts body image information from the captured image information of the front and side surfaces acquired by imaging. Thereafter, body image information and the like are transferred to the information processing apparatus B, and the information processing apparatus B obtains the body height, bust, waist, hips, and other sizes of the measurement subject and displays them on the monitor 24. Below, the structure and process form which implement | achieve this process are demonstrated.

[Photographing device]
As shown in FIGS. 2 and 3, the photographing apparatus A converts the optical information from the optical lens 11 provided in the body 10 into a digital signal using a photoelectric conversion element (not shown) in the body, thereby capturing photographed image information. The imaging part 12 which produces | generates is provided. Externally, there is no significant difference from a commercially available digital camera, but the body 10 has a shooting angle acquisition means 13 for acquiring shooting angle information in the tilt direction at the time of shooting, and a subject H at the time of shooting. Distance measuring means 14 for measuring the distance.

  When photographing with the photographing apparatus A, the angle around the vertical axis Y in the vertical direction of the body 10 is referred to as a yaw angle, and the angle around the horizontal axis X in the horizontal direction of the body 10 is referred to as a tilt angle. An angle around the longitudinal axis Z in the longitudinal direction is referred to as a roll angle.

  The photographing angle acquisition unit 13 includes three distance sensor units 13S that measure the distance to the measurement subject H by using ultrasonic waves, and the distance to the background 1 that is measured by the plurality of distance sensor units 13S. If there is a difference, the yaw angle and tilt angle are measured by the principle of triangulation, and the measured value is output as shooting angle information. The measurement by the distance sensor unit 13S is preferably performed when only the background 1 is photographed. As a result, preparation for photographing of the measurement subject can be efficiently performed. The distance measuring unit 14 measures the distance from the person to be measured H using ultrasonic waves. Note that the photographing angle acquisition unit 13 and the distance measurement unit 14 may use infrared rays or radio waves such as microwaves instead of ultrasonic waves.

  Further, the imaging angle acquisition means 13 combines the weight and an angle sensor such as a potentiometer so as to measure the imaging direction with respect to the gravitational direction in order to measure the tilt angle, whereby a signal from the angle sensor is used as imaging angle information. It may be output.

  The captured image information captured by the imaging unit 12 is assumed to be in the RAW data format of the 8-primary gradation of the three primary colors R (red), G (green), and B (blue). For example, the data may have a gradation exceeding 9 bits such as JPEG format or GIF format. The captured image information may be gray scale information as long as it has a multi-gradation such as 8 bits.

  The imaging unit 12 provides identification information to the photographed captured image information, and also provides a photographing timing signal and identification information to the photographing angle acquisition unit 13 and the distance measurement unit 14.

  The body 10 includes a body image extraction unit 15 that extracts body image information from captured image information, an image correction unit 16 that corrects distortion of the body image information, and a communication unit 17 that sends information through the communication cable 4. The storage information generation means 18 for generating information to be stored in the medium M, and the media drive 19 for storing information in the medium M such as a flash memory are provided.

  The body image extraction means 15, the image correction means 16, and the stored information generation means 18 are configured by software, but some or all of these are configured by a combination of software and hardware. It may be configured only by hardware such as logic.

  The body image extraction unit 15 performs background storage processing 15a for storing background image information in a storage such as a semiconductor memory, and determines a density difference between the stored background image information and captured image information obtained by photographing the person H to be measured. A density difference determination process 15b is performed, a contour specifying process 15c for specifying the contour of the measurement subject in the captured image information is performed based on the density difference, and the body image is obtained from the captured image information based on the identified contour. A body image extraction process 15d for extracting information is performed. These processes are performed in this order, and body image information is extracted from the captured image information by these processes.

[Information processing equipment]
The information processing apparatus B includes a general-purpose computer 21, a keyboard 22 on which an operator inputs information, a mouse 23 that functions as a pointing device, and a monitor 24 that displays image information. The general-purpose computer 21 is connected to the database 25 and the printing device 26.

  In the information processing apparatus B, a configuration in which the database 25 is provided outside the general-purpose computer 21 is shown, but the database 25 may be built in the general-purpose computer 21. The database 25 may be connected to the general-purpose computer 21 via a network such as the Internet.

  The general-purpose computer 21 has a basic configuration including a CPU that processes information, a semiconductor memory, and an operating system, and a media drive 31 that acquires information from the media M. The general-purpose computer 21 includes a communication unit 33 that acquires information via the communication cable 4, an information acquisition unit 32 that acquires information from the communication unit 33 or the media drive 31, and body image information based on the distance information.

  The size correcting unit 34, the body shape processing unit 35, the 3D image generating unit 36, the display processing unit 37, the GUI processing unit 38, and the information management unit 39 are configured by software. Some or all of these may be configured by a combination of software and hardware, or may be configured only by hardware.

  The body shape processing unit 35 obtains a corresponding body shape from the database 25 based on the front and side body image information corrected by the size correcting unit, and a measurement for specifying the measurement position in the acquired body shape. A position specifying process 35b and a size acquiring process 35c for acquiring the size of the body at the measurement position are performed.

[Process type]
The outline of the measurement process in the measurement system of the present invention is shown in the flowchart of FIG. 4, the process form in the photographing apparatus A is shown in the flowchart of FIG. 5, and the process form in the information processing apparatus B is shown in the flowchart of FIG.

[Measurement processing]
In the measurement process, the background device 1 is photographed by the photographing apparatus A, and photographed image information of the front and side surfaces of the measurement subject H is acquired by photographing with the photographing apparatus A (steps # 01 and # 02). Next, a body image information generation routine for extracting body image information from the captured image information and correcting distortion of the body image information is executed in the image capturing apparatus A (step # 100).

  When the subject H is photographed from the front by the photographing device A, a part of the back of the subject H is lightly brought into contact with the background 1 and the subject H is photographed from the side. It is effective to bring a part of the body such as the shoulder of the body into contact with the background 1 in terms of eliminating the variation in distance and eliminating the change in the size of the body image information included in the captured image information.

  Next, the body image information and the distance information are transferred to the information processing apparatus B (step # 03), and the information processing apparatus B corrects the size of the body image information based on the distance information. The body shape corresponding to the corrected body image information is determined, the size of each part of the body (including the designated part) is acquired, and a size measurement routine for displaying the acquired size on the monitor 24 is executed (#) 200 steps).

[Body image information generation routine]
In this body image information generation routine, background image information obtained by photographing the background 1 is acquired from the imaging unit 12, and the background storage process 15a stores it in a semiconductor memory (not shown) in the apparatus. Next, photographed image information obtained by photographing the person to be measured H is acquired from the imaging unit 12, and the body image extracting means 15 stores it in a semiconductor memory in the apparatus. In addition, the shooting angle information at the time of shooting is acquired from the shooting angle acquisition unit 13, the distance information at the time of shooting is acquired from the distance measurement unit 14, and the information is stored in the semiconductor memory in the apparatus (# 101 to ##). 103 steps).

  The body image extraction unit 15 determines the density difference between the background image information and the captured image information in the density difference determination process 15b, and specifies an area having a large density difference as the outline in the outline specifying process 15c. After the contour is specified in this way, the region surrounded by the contour in the body image extraction process 15d is extracted from the photographed image information as body image information. Further, in the body image extraction process 15d, the body image information The binarization (monochrome two gradations) with black as the person and white as the background (step # 104).

  In this body size measurement system, after the background 1 is photographed, a process for photographing the person H to be measured from the front and from the side is required. Therefore, the person H to be measured is also included in the processes of # 102 to # 104. Similar processing is repeated for the captured image information captured from the front and the captured image information captured from the side (step # 105).

  Next, the image correction unit 16 corrects the distortion of the body image information from the body image extraction unit 15 by processing such as affine transformation based on the shooting angle information acquired from the shooting angle acquisition unit 13 (step # 106).

  For example, when photographing from the direction of looking down at the person to be measured H, distortion of the characteristic that is enlarged toward the upper part of the person to be measured H is generated. The distortion of the characteristic that is enlarged toward the lower part of the region is generated. For this reason, the image correction means 16 corrects the body image information based on the photographing angle information so as to correct this distortion.

  Thereafter, two types of body image information (binarized information) of the front and side corrected by the image correcting unit 16 and the distance information from the distance measuring unit 14 are transmitted from the communication unit 17 to the information processing apparatus B. Is transmitted. At the same time, the stored information generating means 18 transmits the two types of body image information of the front and the side corrected by the image correcting means 16 and the distance information from the distance measuring means 14 to the media drive 19, and Is stored in the medium M (step # 107).

[Size measurement routine]
In this size measurement routine, the information acquisition unit 32 performs processing for acquiring body image information and distance information via the media drive 31 or the communication unit 33, and information such as a name for identifying the person H to be measured. Is obtained from the keyboard 22 (step # 201).

  Next, the size correcting means 34 corrects the size of the body image information based on the distance information (Step # 202). This size correction processing is not limited to processing for simply enlarging or reducing the size of the body image information. For example, for example, an enlargement rate of body image information (a numerical value less than 1 is a numerical value exceeding 1 and a reduction rate). May be a process of calculating information indicating the enlargement ratio) and storing the information on the enlargement ratio in a header of a file constituting the body image information. Incidentally, when the enlargement ratio is given in this way, the body shape processing means 35 determines the size of the body image information by calculation based on the enlargement ratio.

  The body shape processing means 35 acquires the corresponding body shape information from the database 25 based on the front and side body image information, and displays the body image information on the monitor 24 as shown in FIG. Further, the 3D image generation means 36 generates 3D image information corresponding to the body image information based on the body shape information acquired in this way (step # 203).

  In the database 25, a large number of body shape information (specifically, a three-dimensional shape of the body can be specified) for identifying one body shape based on the front body image information and the side body image information. Information such as parameters and information on a three-dimensional model of the body) are stored in advance, and one three-dimensional shape (3D shape) is inevitably determined by determining the body shape. It is assumed that information on the size of fixed positions such as bust, waist and hip is associated with this body shape information, and the information on the size thus associated is also stored in the database 25.

  The 3D image generation means 36 performs processing to generate a 3D image corresponding to the body shape acquired from the database 25, but this 3D image is not displayed until the body shape comparison tab 50C shown in FIG. 9 is selected.

  In step # 203, an output screen 50 shown in FIG. Front body image information is displayed in the front image display area 51 of the output screen 50, and side body image information is displayed in the side image display area 52. In the information display area 53 at the lower position, the name of the person to be measured, the measurement date and time, and the numerical value of the size of the designated position are displayed. In particular, the sizes of fixed positions such as bust, waist and hip are displayed in the initial stage.

  It should be noted that the processing form may be set so that the outer peripheral length of the set portion of the body shape information is calculated by calculation and displayed as a dimension even at a predetermined position such as bust, waist, hip, and the like.

  Moreover, it is also possible to display the size of the designated position by designating and clicking an arbitrary position of the body image information with the cursor Cu displayed on the monitor 24. In this way, the measurement position can be arbitrarily set. When set, the size is acquired by calculating the outer peripheral length of the designated part of the body shape information by calculation. If there is no designation, the size of the measurement position set as the initial position (default) of bust, waist, hips, etc. is acquired and displayed on the monitor 24 (steps # 204 to # 207).

  As described above, when displaying the size information of the position designated by the cursor Cu on the monitor 24, a processing mode for obtaining the size by calculation based on the body shape every time the click is performed is set. The information may be stored in the database 25 in association with the body shape information and acquired together with the body shape information. In this case, the size of each part of the body can be immediately displayed on the monitor 24 without performing calculation.

  In the information display area 53, a height input area 53a and a weight input area 53b are formed, and a cursor Cu is set in these areas so that information can be input from the keyboard 22.

  FIG. 7 shows a default state of the output screen 50 displayed on the monitor 24. In this default state, the basic information tab 50A is selected.

  Then, by selecting and clicking the save button 54 formed at the bottom of the output screen 50 with the cursor Cu, the information displayed on the output screen 50, the body shape information generated by the 3D image generating means 36, and Is stored as a history associated with the name of the person being measured (steps # 208 and # 209).

  By selecting and clicking the history display tab 50B of the output screen 50 with the cursor Cu, the history information stored in association with the name can be displayed as shown in FIG. In this screen, a period input unit 55 is formed. In the period input unit 55, a date and time indicating the past of several months with reference to the present is displayed as a default, and the history in this period is extracted from the database 25, and the history The history is graphed and displayed in the display area 57.

  Further, in a state where the history display tab 50B is selected, the date and time is input from the keyboard 22 after the period input unit 55 is selected with the cursor Cu, and the OK button 56 is selected with the cursor Cu and clicked. The history in the period is extracted from the database 25 and displayed in the history display area 57 (Steps # 210 and # 211).

  Next, by selecting and clicking the body shape comparison tab 50C of the output screen 50 with the cursor Cu, it is possible to display a 3D image stored in association with the name as shown in FIG. In this screen, a period input unit 58 is formed. In the period input unit 58, a date and time indicating a past of several months based on the present is displayed as a default, and a 3D image in this period is extracted from the database 25. It is displayed on the comparison display unit 60.

  Further, in the state where the body shape comparison tab 50C is selected, the date and time is input from the keyboard 22 after selecting the period input unit 58 with the cursor Cu, and the OK button 59 is selected with the cursor Cu and clicked. The 3D screen in the period is extracted from the database 25 and displayed on the comparison display unit 60 (steps # 212 and # 213).

  These displays are continued until the end button 61 of the output screen 50 is selected and clicked with the cursor Cu (step # 214).

[Effect of the embodiment]
As described above, after the background 1 is captured by the photographing apparatus A and the background image information is acquired, the person H to be measured stands in front of the background 1 and continuously photographs the front and side surfaces with the photographing apparatus A. The captured image information is acquired, and the imaging angle information and the distance information at the time of the imaging are acquired. In the photographing apparatus A, body image information is extracted from the density difference between the background image information and the photographed image information, and binarized. Further, the distortion of the body image information is corrected based on the photographing angle information. By correcting the distortion in this manner, for example, even when the operator performs shooting with the imaging apparatus A held by hand, the distortion can be appropriately removed.

  Next, in the general-purpose computer 21 of the information processing apparatus B, the size of the body image information is corrected based on the distance information. By correcting the size in this way, for example, the distance between the body image information on the front side and the body image information on the side surface at the time of shooting can be reduced as in the case where the operator has taken the image with the imaging device A in hand. Even if they are different, the body image information can be converted into an appropriate size.

  Thereafter, body shape information corresponding to the corrected body image information of the front and side surfaces is acquired from the database 25, so that an appropriate body shape can be specified without performing any special calculation, and the size of each part of the body can be acquired. It becomes possible. By displaying the acquired size as a numerical value on the output screen 50 of the monitor 24, the size of each part of the body can be accurately grasped.

  In particular, it is possible to display information from the past to the present graphed as history information on the output screen 50, and in the same way, 3D shapes from the past to the present can be compared. By displaying it, it becomes possible to grasp the transition of the body shape visually.

  Although not shown in the flowchart, the display content of the output screen 50 can be printed out by the printing device 26.
