The next detection areas 37 are collected one by one, after one row of information is collected, the information is driven by the motor 45 behind the head, and the supporting belt 20 is scanned to move back or forward by half the detection unit 36 under the drive of the driving belt 43, so that the next row of information is collected, and the edges of the upper detection area 37 and the lower detection area 37 are overlapped with each other, so that the integrity of the information collection of the hair, the scalp and the like of the head top and other parts of the tested person is ensured. Because the hair of the head of the person to be tested can fall back or forward at the same time when the scanning support belt 20 moves back or forward, the quality of image information collection is affected, a circle of pulling teeth 25 can be preferably uniformly distributed outside the lower end of the detection column 24, and the detection column 24 is driven to rotate by the pulling teeth driving wires 26 at the upper part of the detection column to pull out the uniformly backward or forward falling hair, so that the hair is oriented with the detection column 24 as the center, and the quality of image collection is improved. The six teeth-pulling driving wires 26 on the scanning support belt 20 are contacted with the upper parts of all the detection posts 24 on the six teeth-pulling driving wires one by one, and then pass through the driving belt 43 and then are wound on the teeth-pulling driving wire driven wheel 47.
Further, in the preferred embodiment, the top of the scanning support belt 20 is connected to the driving belt 43, the lower end of the driving belt 43 contacts with the driven belt wheel 44, the post-head motor 45 drives the post-head motor driving wheel 46 to rotate, and when the post-head motor driving wheel 46 contacts with the driven belt wheel 44, the top of the scanning support belt 20 is driven to move back and forth on the median sagittal plane of the top of the head of the person to be tested. Because the detection column 24 disposed on top of the scanning support belt 20 is always running on the mid-sagittal plane of the head of the person under test, the mid-sagittal plane boundary of the head of the person under test can be marked in the image acquired by this fixed detection column 24. The post-head motor 45 and the post-head motor driving wheel 46 can translate under the control of a similar switch circuit, and the post-head motor driving wheel 46 can be selectively contacted with the driving driven wheel 44 or the tooth-pulling driving wire driven wheel 47. When contacting with the tooth-pulling driving wire driven wheel 47, the tooth-pulling driving wire 26 is driven to move, so that all the detection columns 24 on the six scanning support belts 20 are integrally driven to rotate, and the tooth-pulling 25 at the lower end of the detection column 24 pulls out hairs which fall backwards or forwards uniformly in rotation.
Further, a head cover 53 can be arranged outside the acquisition device, as shown in fig. 8, so as to prevent external light from entering, corresponding parts of the hair scanning mirror 30 can be exposed, the replacement, the installation or the disassembly of operators are convenient, different light source groups 31 can be freely replaced before the scanning detection of the parts such as the head top and the like of the detected personnel, polarizing plates and wave plates can be freely installed or removed, light sources with corresponding parameters can be selected for specific detection, and specific light sources and standards are arranged for different detection, so that the comparability of the acquired images and detection results is ensured; further, the components with weight bias such as the head motor 41 and the back motor 45 can be arranged in the shoulder support 50, the components such as the device main power supply 51 and the control system 52 are also arranged in the shoulder support 50, the shoulder support 50 is connected with an external computer system through a connecting wire, the collected image information is transmitted into the computer system in real time for processing, and the information such as the result and the image is stored in a local memory after the processing is finished, or is uploaded into a server or a network cloud system for later calling.
Still preferably, the scanning detection column 21 and the hair scanning mirror 30 according to another preferred embodiment of the present invention may be integrally connected, the light source column support 23 is not connected to the light source column 22, and is directly and dispersedly disposed on the outer edges of both sides of the scanning support belt 20, so as to support the scanning support belt 20 to maintain a constant distance from the scalp of the person to be detected, and then the middle of the scanning support belt 20 is grooved, the light source column 22 and the detection column 24 are directly and fixedly connected to the front end of the hair scanning mirror 30, and run together with the hair scanning mirror 30 in the groove of the scanning support belt 20, and when the detection is disposed, the distance between the adjacent detection areas 37 may be smaller, so that the detection is finer, and the image magnification may be higher. Except for this variation, the same as in the above preferred embodiment can be used; the scanning detection column 21 in the preferred embodiment may be replaced by an optical fiber image transmission bundle, one end of which is inserted into the hair of the person to be tested like the scanning detection column 21, and transmits the image information of the hair and scalp on the top of the head to the other end, and an optical lens system may be provided in front of the lower end of the optical fiber image transmission bundle. Then the upper end of each optical fiber image transmission beam is intensively arranged at any proper position of the device according to a certain sequence, and then the hair scanning mirror 30 collects the image information uniformly. The information collection can be more concentrated by arranging the structure, the head of the person to be tested can be separated from the track arrangement of the hair scanning mirror 30, the structure is simpler, the number of the motors and the hair scanning mirror 30 can be reduced, and the information collection efficiency is improved.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
