Referring to fig. 1, fig. 1 is a schematic view of a scene for adjusting the lifting and lowering of a display screen according to an embodiment of the present disclosure, where the scene includes a user 101, an image sensor 102, an apparatus 103, a display screen and a linkage component 1031, where the image sensor 102 is a camera, and the apparatus 103 is a mobile diagnostic table. The camera may perform data transmission with a mobile diagnostic table through a Universal Serial Bus (USB) communication interface or other interfaces, or the camera is a component in the mobile diagnostic table; the screen and linkage unit 1031 is a unit in the mobile diagnostic table, and the mobile diagnostic table controls the elevation of the screen by the screen and linkage unit 1031.
The camera collects dynamic imaging information and static imaging information of a user 101 and sends the dynamic imaging information and the static imaging information to the mobile diagnosis platform, the mobile diagnosis platform identifies gesture information in the dynamic imaging information, and when the gesture information is matched with a first instruction, the mobile diagnosis platform carries out operation of calculating the height of the user; the mobile diagnosis platform receives the static imaging information, obtains the distance between the user 101 and the display screen through an infrared sensor, and calculates the height of the user according to the static imaging information and the distance; the mobile diagnosis platform automatically adjusts the height of the display screen according to the height of the user until the difference between the height of the center of the display screen from the ground and the height of the user is within a preset range (for example, the difference between the height of the center of the display screen and the height of the user is 5cm or-8 cm).
It can be seen from the above-mentioned scene that above-mentioned equipment can be according to the height of above-mentioned user's body automatically regulated display screen, and when above-mentioned user's height is higher or shorter, above-mentioned equipment can be adjusted above-mentioned display screen to suitable position, and this kind of regulation mode efficiency is higher more intelligent.
Referring to fig. 2, fig. 2 is a schematic flow chart of another XX method according to an embodiment of the present invention, which includes, but is not limited to, the following steps.
Referring to fig. 2, fig. 2 is a schematic flow chart of a method for adjusting the lifting of a display screen according to an embodiment of the present application, where the method includes, but is not limited to, the following steps.
Step S201: the device acquires imaging information of a user through the image sensor.
The imaging information includes static imaging information and dynamic imaging information of the user, the image sensor is exemplified by a camera, and the apparatus is exemplified by a mobile diagnostic table.
Specifically, the camera acquires static imaging information of the user, the static imaging information including an imaging focal length f (e.g., 35cm), coordinates (e.g., a '(247, 709)) of a highest pixel point a' of the user, and a lowest pixel point B '(e.g., B' (281, 152)) of the user; the camera acquires dynamic imaging information of the user, which includes gesture information of the user (e.g., "waving hand", "bartering"), and the like. The camera sends the static imaging information and the dynamic imaging information to the mobile diagnostic table, and the mobile diagnostic table obtains the static imaging information and the dynamic imaging information of the user.
Step S202: the device calculates the height of the user based on the imaging information.
Specifically, before the mobile diagnostic table calculates the height of the user, the mobile diagnostic table needs to recognize gesture information in the dynamic imaging information of the user, and match a first instruction from pre-stored operation behaviors according to the gesture information (for example, the gesture information of the first instruction is set to be "than heart"), when the user performs an operation of "waving hands" or "waving hands", the first instruction cannot be matched, and only when the user performs a gesture of "than heart", the mobile diagnostic table of the mobile diagnostic table starts to calculate the height of the user, so that interference of some other gesture information is avoided, and a device continuously performs the calculation operation to bring large technical overhead. .
In addition, the mobile diagnosis platform acquires the distance between the user and the display screen sent by the infrared sensor, and calculates the height of the user according to the static imaging information of the user and the distance between the user and the display screen by the imaging principle. Referring to fig. 3, fig. 3 is a schematic view of a scene for acquiring imaging information of a user, where the scene is taken while the user is standing, and the scene includes a plane 301 of the user, a plane 302 of a display screen, and a focal plane 303 of a camera, where a point E is in the plane 301, a point O is in the plane 302, a point F is in the focal plane 303, and the point E, the point O, and the point F are on the same straight line. From the scene diagram, it can be derived that the distance between the user and the display screen (i.e. the object distance u) is LOEThe distance between the display screen and the image of the user (i.e., the distance f) is LOFDue to LOERatio LOFWhen the image is 2 times larger, the static imaging information of the user appears on the focal plane of the camera and is a real image reduced in an inverted state.
The mobile diagnostic table processes the background of the received static imaging information and only obtains the imaging information of the user. Referring to fig. 4, fig. 4 is a schematic view of a user's geometric imaging scene. According to the imaging principle in fig. 3, a ' in fig. 4 corresponds to the highest pixel point of the user, and B ' corresponds to the lowest pixel point of the user, wherein as can be seen from fig. 4, the coordinates of the pixel point at a ' point are (247, 709), the coordinates of the pixel point at B ' point are (281, 152), and the imaging height of the user is the distance between a ' and B ' in the figure, wherein the euclidean distance L between a ' and B ' can be calculated according to the coordinates of the points a ' and BA′B′Comprises the following steps:
Figure BDA0002395395500000061
according to the Euclidean distance L of the user in the imaging informationA′B′The Pixel Per Inch (PPI) may be calculated to obtain the actual distance H in the imaging information of the userA′BThe above PPI is used to characterize how many pixels per inch are present, namely:
Figure BDA0002395395500000062
as can be seen from FIG. 4, the imaging focal length f is 35cm, the distance u between the user and the display screen is 110cm, and then in the case of Δ AOB and Δ A 'OB' in FIG. 4, the height H of the user can be calculated by using a similar method of trianglesABWherein, the height H of the userABComprises the following steps:
Figure BDA0002395395500000063
substituting the PPI (260), u (110 cm), and f (35 cm) into the above formula to obtain HABApproximately 171cm, i.e. the above-mentioned usersIs 171cm in height.
It can be seen that the height calculation utilizes the imaging principle, and the calculation method is simple.
Step S203: the equipment controls the lifting of the display screen on the equipment according to the height.
Please refer to fig. 5, fig. 5 is a schematic structural diagram of a device for adjusting the elevation of a display screen, the schematic structural diagram includes a display screen 501, an electric push rod 502, a slider 503 and a slider support 504, the electric push rod 502, the slider 503 and the slider support 504 form a linkage mechanism, when the mobile diagnostic table calculates the height of the user and inputs a start signal to a driving device, the electric push rod 502 in the linkage mechanism starts to operate, so that the linkage mechanism controls the elevation of the display screen, when the mobile diagnostic table inputs a stop signal to the driving device, the electric push rod 502 stops operating, so that the difference between the height from the ground of the center position of the display and the height of the user is within a preset distance range, wherein the preset distance range is determined by the distance u between the user and the diagnostic table, the upward gazing angle β of the user and the downward gazing angle γ of the user, for example, the distance u is 30cm, the upward gazing angle β of the user is 30 h, and the upward gazing distance is determined by the distance γ of the user↑Distance of downward line of sight is h↓And then:
Figure BDA0002395395500000071
Figure BDA0002395395500000072
is calculated to obtain h↑Is 17.3cm, and h is calculated↓And when the preset range is 30cm, the preset range is 17.3 cm-30 cm. If the height of the user is 171cm, the height of the center of the display screen from the ground is 141cm (171cm-30cm) at the lowest and 188.3cm (171cm +17.3cm) at the highest. In addition, ifIf the user does not adapt to the adjusted height of the display screen, the user may perform fine adjustment on the display screen in a "blinking" manner (for example, when the user performs two consecutive "blinks", the display screen may be adjusted by 2cm upward, and when the user performs three consecutive "blinks", the display screen may be adjusted by 2cm downward), and the user may perform the "blinking" operation for a plurality of times so that the display screen is adjusted to the height that the user considers appropriate.
In the method described in fig. 2, the device can automatically adjust the height of the display screen according to the user's body, and when the user's body is tall or short, the device can adjust the display screen to a proper position, which is more efficient and intelligent.
