Handheld electronic circumference measuring instrument

Abstract

The invention belongs to the field of measuring instruments, and particularly relates to a handheld electronic circumference measuring instrument which comprises a shell, an arc-shaped groove is formed in one side of the shell, a displayer is fixedly connected to one side of the shell, two control switches are fixedly connected to one side of the shell, keys are installed on the two control switches, the two keys are movably connected to the shell, an induction circuit board is fixedly connected in the shell, a ruler belt wheel lower fixing plate is fixedly connected to the inner wall of one side of the shell, and a motor is fixedly connected to the ruler belt wheel lower fixing plate. According to the invention, a high-precision grating counting scheme is adopted, the counting is accurate, the handheld electronic circumference measuring instrument is a handheld device, the movement is convenient, the operation is simple, one-key ruler collection, one-key data locking and automatic data uploading are realized, the measurement method is simple, the requirements on use scenes are not too many, the popularization and the use are convenient, a traditional measurement mode is electronized and standardized to the maximum extent, and the use requirements of current measurement are better met.

[0002] Measurements are the collective name of bust, waist and hip circumference. The horizontal circumference of the chest from the nipple point, the horizontal circumference of the waist through the center of the navel, or the circumference of the midpoint line between the lowest point of the rib and the upper edge of the iliac crest. , measured at the end of exhalation and before inhalation, there are currently two common methods of measuring circumference: one is traditional manual measurement, which is read by human eyes and recorded manually, and the other is high-end measurement For the human body shape, the 3D depth-of-field camera is used to take image synthesis technology to establish a human body model; for the measurement of the human body shape, most of the traditional manual measurement uses a soft ruler for measurement, which is read by the human eye and recorded manually. Due to the reading by the human eye, The possibility of deviation is greater, and the measurement data can only be recorded manually, and finally manually entered and uploaded. There are too many intermediate links and errors are prone to occur. However, the scheme of using 3D depth-of-field camera to shoot image synthesis technology and establish a human body model is too expensive. Heavy equipment, poor portability
