At this point, the criteria matching the healthcare worker may be selected as: the patient sends the measured parameter results to a designated expert for diagnosis, either by matching the local doctor registered in the App or by social software.
In addition, before the steps S1 and S2, i.e. before the first image and/or the second image are acquired, the following steps are performed: if the horizontal axis of the photographing surface of the photographing apparatus is adjusted to be parallel to the ground surface, no image can be obtained.
Specifically, the apparatus has built-in an image pickup apparatus and an electronic level, wherein the electronic level and the image pickup apparatus are arranged in the following positions: the base measuring surface of the electronic level is parallel to the horizontal axis of the shooting surface of the shooting equipment, and the base measuring surface of the electronic level is horizontal to the ground surface. In addition, the electronic level and the image pickup apparatus are communicatively connected to the processor, and the processor acquires the horizontal state of the electronic level, thereby acquiring the horizontal state of the image pickup apparatus image pickup surface, and can determine whether the horizontal axis of the image pickup apparatus image pickup surface is parallel to the ground surface. The image pickup apparatus is controlled to acquire an image only when the horizontal axis of the image pickup surface of the image pickup apparatus is parallel to the ground surface.
In an embodiment of the present invention, the processor processes the information and displays the information in a displayable data form on a display screen, so as to remind a user of the current horizontal state of the image capturing apparatus. Such as: the image acquisition focusing area of the image pickup device is displayed on the display screen in a block diagram mode, a datum line corresponding to the measuring surface of the base is displayed, and the user is reminded of the current horizontal state of the image pickup device through visual comparison of the block diagram and the datum line. Alternatively, the display screen displays the image acquisition focus area of the image pickup apparatus at this time in a block diagram, the block diagram displaying the error mark when the horizontal axis of the image pickup apparatus photographing surface is not parallel to the ground surface, and the block diagram displaying the correct mark when the horizontal axis of the image pickup apparatus photographing surface is parallel to the ground surface. In this way, the user is allowed to more intuitively view the horizontal state of the current image capturing apparatus.
In the embodiment of the invention, the reference measuring surface of the electronic level is arranged to be parallel to the horizontal plane of the equipment, so that a user can more conveniently control the horizontal state of the image pickup equipment and can also be reminded of the horizontal angle of the equipment at the moment.
In addition, in order to better identify the images, the following steps are performed before the steps S1 and S2, i.e. before the first image and/or the second image is acquired: the distance between the photographing surface of the photographing apparatus and the face of the measured person is adjusted within a set range. If not, the position of the image pickup apparatus is adjusted until the above distance condition is satisfied.
In the embodiment of the present invention, the distance between the photographic subject and the image capturing apparatus is determined with the subject distance of the image capturing apparatus. Specifically, the image capturing apparatus is communicatively connected to the processor, the processor acquires the object distance of the image capturing apparatus at this time, and when the object distance displays the photographed object and the photographing surface is greater than the set distance, error information is displayed on the display screen, and the image capturing apparatus is set to be unable to acquire an image; when the distance between the focal length display photographic subject and the photographic surface is not greater than the setting data, correct information is displayed on the display screen, and the image pickup apparatus can acquire an image at this time.
In an embodiment of the present invention, it may be displayed in the following manner: the image acquisition focusing area at this time of the image pickup apparatus is displayed in a block diagram on the display screen, and the conversion of the error information and the correct information is displayed in a color change of the block diagram.
The order of the two steps of "adjusting the distance between the imaging apparatus imaging surface and the subject within the set range" and "adjusting the horizontal axis of the imaging apparatus imaging surface parallel to the ground surface" is not taught.
The second case is different from the first case in that: in the second case, only one image needs to be acquired, and the non-contact measurement method for the head and face, the limb movement angle and the body posture of the human body comprises the following steps:
a1, acquiring an image of a measured person, processing the image, wherein the measured person is positioned at a measuring position, marking a measuring reference line and a measuring line, and overlapping coordinate axes of the measuring reference line and a measuring coordinate system; and
a2, calculating an included angle between the measuring line and the measuring datum line, and obtaining the inclination angle of the measuring part.
When the measurement content is the facial tilt angle of the human head, the measurement reference line refers to the connecting line between the eyebrow points and the lip bead points of the human body, namely, the positions of the eyebrow points and the lip bead points of the human body of the measured person need to be identified at the moment.
Measurement lines include, but are not limited to, eyebrow alignment, canthus alignment, nasal midline, mouth angle alignment, and dental midline. Correspondingly, the eyebrow trimming horizontal line needs to mark the highest points of eyebrows at two sides; the nose midline is required to mark a mark point on the nose midline, and the mouth angle horizontal line is required to mark the highest points on two sides of the mouth angle; the midline of the tooth requires marking points for marking the teeth in the upper and lower middle.
Of course, steps identical to steps S4 and S5 remain included at this time. The standard for normal inclination angle of the five sense organs should be: the eyebrow trimming horizontal line, the canthus horizontal line and the mouth angle horizontal line are perpendicular to the measuring datum line; the nasal midline and the dental midline are parallel to the measurement reference line.
Of course, two steps of "adjusting the distance between the imaging apparatus imaging surface and the subject within the set range" and "adjusting the horizontal axis of the imaging apparatus imaging surface parallel to the ground surface" are still included.
When the measured inclination angle is poor body posture, the measurement position is as follows: the person to be measured is positioned at the position where the body is vertical, the feet are gathered, the arms naturally drop, and eyes are opened in front of the head-up. The measurement reference line is a human midline, and at this time, the positions of the vertex middle point and the sole middle point of the measured person need to be identified.
Measurement lines include, but are not limited to: nasal tip connection line, shoulder connection line, earlobe connection line. Correspondingly, the nose tip connecting line needs to mark the nose tip position, the shoulder connecting line needs to mark the shoulder position, and the earlobe connecting line needs to mark the earlobe position.
In other embodiments, the measurement locations are: the measured person leans against the wall body and keeps the upright state. The measuring datum line is a vertical line perpendicular to the ground, and the measuring line comprises, but is not limited to, a rear brain scoop wall-leaning mark point, a scapula wall-leaning mark point, a buttock wall-leaning mark point, a shank wall-leaning mark point and a connecting line between any two of the heel wall-leaning mark points. The scores of the five-point line, the four-point line, the three-point line and the two-point line can be obtained respectively through the measurement of the angles of the measurement line and the measurement reference line.
The non-contact measurement method for the head and face, the limb movement angle and the body posture of the human body has wide application in medical assistance. The measured person can perform self-test by using equipment provided with the non-contact measurement method of the head and face, the limb movement angle and the body posture of the human body, and obtain accurate diagnosis results and adaptive medical staff according to an accurate diagnosis database. The medical staff can discard the original manual distance measurement mode of the physical ruler to measure the inclination angle, so that the accuracy of detection and the comfort level of the measured person are improved, and an effective disease diagnosis result is obtained in an auxiliary mode.
The present invention is not limited to the above-described preferred embodiments, and any person who can obtain other various products under the teaching of the present invention, however, any change in shape or structure of the product is within the scope of the present invention, and all the products having the same or similar technical solutions as the present application are included.
