Description of the invention (6) The front surface layer 252/352 and an opaque back layer 254/354 and a flat light 256/356 are sandwiched between the front surface layer and the back layer. In use, the light emitted by the light source 256/356 diffuses through the front surface layer 252/352 and provides a uniform, bright and clear background on the inner surface of the captured image. As an alternative design, each background board 250/350 can also be a simple blue wooden board with an inner surface to provide a flat blue background for capturing images. The clear background provided by both background boards can enhance the sharpness of the image outline captured on the monitor screen 452, so that the image outline can be more easily recognized by the image processing unit 420. As shown in Figs. 4 and 5, "the cubicle 1 of the present invention has an internal space to accommodate the customer 20", and a chair 150 can be placed at a predetermined position, and the customer 20 can sit directly on the chair after entering. The chair 150 has a seat 152 and a backrest 154, and a support bar 156 fixed on the platform 05. The customer 20 sits upright on the chair 150 with his back (shoulders) resting on the backrest 154 of the chair 150. The height of the seat 152 is adjusted so that the neck of the customer 20 is approximately at or very close to the intersection of the image capturing axes X and Y (see FIG. 7). The cameras 200 and 300 are used to capture the front image A and the side image B of the upper body of the customer 20 with the corresponding background plates 25 and 35 as the background, and display them on the monitor screen 452 one by one (Figure 8 and Article 9 囷). Image a and image B should have a head and a shoulder including the upper end of the arm. In order to select a suitable pillow for the customer 20, three biometric data or dimensions of the customer 20 must be known, from which the obtained pillow can be used to the head of a sleeping person lying on his back and side. The size of the paper is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 public love) 9 561034 A7 B7. 5. The invention description (7) can give support. The first dimension D1 (ie shoulder width) is the distance from the ear on either side, preferably the earlobe to the shoulder on that side, that is, the distance between the vertical lines 21 and 22 in Figure 8; The two dimensions D2 (the depth of the occipital bone) is the distance between the occipital bone and the scapula, that is, the distance between the vertical lines 23 and 25 in the 9th iliac crest. The distance from the shoulder blades is the distance between the vertical lines 24 and 25 in Figure 9. The computer 400 is loaded with a program that can measure three sizes D1 to D3 based on the images A and B captured by the cameras 200 and 300 and displayed on the monitor screen. The customer 20 is asked to sit down before the measurement is actually started And keep the spine straight up and the head inclined forward so that the upper body seems to be lying on an imaginary vertical bed. In order to make it clear how the head should be tilted at a certain angle, the better solution is to On the monitor screen 452, a set of equidistant parallel lines 26 is superimposed on the image B as a reference. As shown in FIG. 10, these parallel lines 26 are inclined about 100 relative to the vertical lines, and the head should be tilted to the mouth and The plane on which the chin or face lies generally overlaps a reference line 26. Measured by the image processing unit 420, first identifying the positions of the ears and shoulders, the occipital bone and the shoulder blades, the back of the neck and the shoulder blades, and identifying the contour and origin of the image A / B or more accurately The clear background provided by the panel 250/350 requires good contrast, such as brightness and / or color. Once the relevant positions are determined, they can be measured for their horizontal resolution or sizes D1 to D3. These dimensions D1 ~ D3 are calculated and calibrated 10 based on the distance between the cameras 200, 300 and customers 20 determined in advance (please read the precautions on the back before filling out this page) This paper size applies Chinese National Standard (CNS) Α4 Specifications (210X297 public attack *) 561034 A7 B7 5. The invention description ((calibration) is transformed into the actual body value of the customer and displayed on the monitor screen 452. The vertical lines 21 to coincide with the identified parts of the customer's body 25 is best displayed on the monitor screen 452 for more visual reference or verification. The three vertical lines 21 to 25 can be moved manually and laterally by the mark icon 27 marked on the upper end of the line. If the vertical line does not coincide with the corresponding part of the customer ’s body, it should be manually moved to the correct position. The database 430 stores a large amount of Pillow size data. These pillows are based on physical therapy research and statistics. They have a wide range of coverage, even if they are not suitable for everyone. Suitable for most people. These materials include the aforementioned dimensions D1 ~ D3, which correspond to the actual thickness of the lower half of the pillow (used to support the back of the neck), and the actual thickness of the middle part (used to support the back of the brain). ), The actual thickness of the left / right half (used to support the side of the building head). Based on the measured dimensions D1 ~ D3, the data in the database 430 is automatically compared with it, and selected for each customer 20 The most suitable pillow.
