Embodiment Construction

[0014] Such as figure 1 , 2 , 3, and 4, the present invention includes a base 1, a crossbeam 4, a vertical guide rod installed between the base 1 and the crossbeam 4, namely connected by the base 1, the crossbeam 4 and three vertical guide rods 8, 15, 23 Form the frame structure.

[0015] A scanning device that moves up and down along the three vertical guide rods 8, 15, 23 and a power drive device that drives the scanning device to move up and down along the vertical guide rods are set on the three vertical guide rods 8, 15, 23 to achieve vertical scanning. , the power drive device for driving the scanning device to move up and down along the vertical guide rod is: a lead screw nut 3 is fixedly installed on the scanning device, a lead screw 2 is installed between the beam 4 and the base 1, and a stepping motor 26 Drive screw 2 to rotate through gear. That is, the output shaft of the stepper motor 26 fixed on the base 1 and arranged downward is connected with a gear 17, and...

Abstract

The invention relates to a three-dimensional body dimension automatic measuring mechanism capable of measuring without taking off clothes of a measured person, which comprises a pedestal, a cross beam, and a vertical guide rod arranged between the pedestal and the cross beam, wherein the vertical guide rod is sleeved with a scanning device moving up and down along the vertical guide rod and a power drive device driving the scanning device to move up and down along the vertical guide rod to achieve vertical scanning, and the scanning device comprises a stepped motor base, a stepped motor arranged on the stepped motor base, a pulley base provided with a driven pulley, a transverse guide rod arranged between the stepped motor base and the pulley base, a toothed belt for connecting the stepped motor with the driven pulley, a sliding block connected on the toothed belt and moving transversely along the transverse guide rod, and an infrared thermodetector and a scanning head which are arranged on the sliding block. The measuring mechanism not only has the advantages of small volume, light weight and compact structure, but also can measure the naked human body dimension quickly and accurately under the condition that the measure person does not need to take off the clothes.

Description

technical field [0001] The invention relates to a mechanical moving part of a non-contact infrared measurement system, which can quickly and accurately measure the bare size of a human body, and is a three-dimensional automatic measurement mechanism for human body size that can be measured without removing the device. Background technique [0002] At present, traditional anthropometric methods mainly use manual tools such as soft feet, angle gauges, altimeters, distance gauges, and slide gauges to perform contact measurements on the human body based on measurement benchmarks. Most of these methods are based on manual measurement or by Due to empirical observation, it is difficult to obtain some feature point data of the human body, and the accuracy of the measurement results is poor. Due to different measurement principles, the existing 3D anthropometric systems generally occupy a relatively large space, and the movement mechanism is complicated, the mass is large, and the o...
