Description

Technical Field

[0001] The present invention relates to the technical field of measuring rulers, and in particular to a facial measuring ruler. Background Art

[0002] At present, with the rapid development of medical, cosmetology, plastic surgery and other fields, facial measurement has become an indispensable part of these fields. Facial measurement is of great significance for evaluating facial structure, making surgical plans, and designing orthodontic and orthognathic plans.

[0003] At present, there are two methods for measuring the face: direct measurement and indirect measurement. The direct measurement method is to use tools such as rulers and calipers to measure directly, while the indirect measurement method is to obtain an optical image of the face of the person being measured through two-dimensional or three-dimensional photography, and then measure on the optical image through software.

[0004] The direct measurement method requires a physical measuring tool. Patent CN214856715U discloses a facial measuring ruler, which includes a measuring ruler body, a ruler handle, a spring, a finger buckle, a fixed ruler screw, a finger ring, a ruler, and a flat ruler scale. The ruler handle is placed in the spring and connected to the ruler. The finger buckle is placed on the top of the ruler handle to press the spring. The ruler is slid into the measuring ruler body, and the ruler is fixed by the fixed ruler screw to read the value. There are finger holes on the measuring ruler body and a flat ruler scale is marked. The device is mainly used for measuring facial data before and during surgery. It can quickly and accurately measure the length, width and concave and convex height of the required measurement position, which can not only shorten the operation time, but also accurately measure the data and reduce medical risks. It is simple, convenient and low-cost to operate. Patent CN210077667U discloses a face measuring ruler, including a fixed frame, a vertical plate located in the vertical direction of the fixed frame, and a horizontal plate located in the horizontal direction of the fixed frame. The surfaces of the horizontal plate and the vertical plate are sleeved with movable blocks, and the bottom of the movable block is fixedly connected to the vertical plate. The fixed frame is provided with a slide groove, and a slider is slidably connected in the slide groove. The bottom of the slider is connected to a telescopic sleeve. The face measuring ruler can measure the length and width of the face by placing the horizontal plate and the vertical plate, and the slider slides on the slide groove, and the width and height of the nose can be measured by cooperating with the telescopic sleeve. It can be operated by one person, and the measurement method is simple and the measurement data is accurate.

[0005] With the different progress of scientific and technological development, the form of the ruler is no longer limited to the form of physical objects such as rulers and compasses. With the rise of 3D face recognition technology, the way of measuring and designing facial data such as plastic surgery has become more convenient. Invention patent CN101347332 discloses a digital measurement system and method for three-dimensional face shape. The method is based on composite structured light projection technology. The composite structured light stripes are formed by modulating several frames of sinusoidal stripes with phase difference perpendicular to their direction by several carrier frequencies of different frequencies and superimposing them. It only needs to collect a frame of composite structured light stripe grating image modulated by the face, through two-dimensional Fourier transform and frequency domain two-dimensional bandpass filtering, and inverse Fourier transform, it is possible to extract several frames of simple sinusoidal stripes with phase shift from one frame of composite stripes, and then use the traditional phase shift technology in phase measurement profilometry to reconstruct the three-dimensional face shape of the target face. The method can easily obtain accurate digital three-dimensional contours of the face, bring new measurement methods and evaluation methods to facial plastic surgery, and promote the digitalization process of medical plastic surgery. After completing the three-dimensional scanning of the face, it is necessary to adjust the data of the reconstructed real face through relevant technical means to bring a satisfactory experience to customers. Patent CN111127642A involves a method for three-dimensional reconstruction of the face. The method uses the RGB laser scanning method to perform color three-dimensional reconstruction. First, the mapping relationship between the pixel coordinate system of the digital camera sampling picture and the world coordinate system is established by the direct calibration method; the standard color plate image under the three-color laser illumination taken by the camera is used to calibrate the photosensitive curve of the digital camera to the three primary colors, that is, to establish the relationship between the camera's three primary color recording value and the standard value. Then, with the face as the target, a complete method from obtaining scanning data to three-dimensional reconstruction is proposed. Finally, the target parameters adjusted in the process of generating the postoperative preview model of the face are input into the host computer, and the size, depth, and angle of the specific facial area to be adjusted are prompted in real time when the doctor is performing the operation, assisting the doctor to complete the facial plastic surgery more finely and perfectly, and the reconstructed digital face three-dimensional model is used for the formulation of plastic surgery plans, advance previews, and assisting the surgical process. Effectively improve users' participation and satisfaction with cosmetic surgeries, and enhance doctors' accuracy in performing cosmetic surgeries.

[0006] The traditional direct measurement method uses physical measuring tools, which is convenient for clinical application, but is greatly affected by factors such as the head position of the subject and the skills and experience of the measurer, so the repeatability is poor and the accuracy is not high. The improved technology has improved the measurement accuracy to a certain extent and achieved multiple uses of one ruler, but the measured data is not comprehensive enough, and the measurement of facial symmetry and subfacial part is not convenient enough. The emerging digital indirect measurement method has high accuracy, but it requires the help of professional equipment and measurement software, and the procedure is cumbersome and not convenient for clinical use. In particular, three-dimensional photography equipment is often expensive, which limits its promotion and application. Utility Model Content
