Description

Technical Field

[0001] The invention relates to campus management equipment, and in particular to a self-adaptive height-adjustable photographing mechanical arm and a control method thereof. Background Art

[0002] In the campus management system, it is often necessary to update and enter student information, and facial information is also a particularly critical piece of student information. Therefore, the recognition and entry of student facial information is also a particularly critical step. Whether the relevant facial information can be effectively entered and the clarity of the facial information will affect the subsequent use and management of the campus.

[0003] At present, students' facial information is generally recorded by individual photography or simple robotic arm photography. Individual photography can easily lead to uneven shooting angles and quality, affecting subsequent use. Although robotic arm-assisted photography can ensure the shooting angle and quality, due to the different heights of each student, the staff needs to constantly adjust the height of the camera, affecting the efficiency of recording. Summary of the invention

[0004] The purpose of the present invention is to provide a photographing robot arm with adaptive height adjustment and a control method thereof in view of the deficiencies and defects in the prior art. The photographing robot arm can automatically identify the height of the person photographing and automatically adjust the relative height position of its photographing camera so that its photographing camera can accurately enter the facial information of the person photographing, which not only ensures its optimal shooting angle but also does not require manual adjustment, thereby reducing the workload of its staff.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a self-adaptive height-adjustable photographing mechanical arm, which includes a mechanical arm main body, a control main board and a lifting mechanism are installed inside the mechanical arm main body, a photographing camera is installed on one side of the lifting mechanism, and the photographing camera is slidably matched with the shell of the mechanical arm main body, a top panel is fixedly connected to the top of the mechanical arm main body, a top ranging sensor is provided below the top panel, and the bottom of the mechanical arm main body is installed on a supporting base, and a standing panel is installed above the supporting base; the lifting mechanism and the top ranging sensor are electrically connected to the control main board respectively, and the control main board controls the lifting mechanism to drive the photographing camera to move to a desired height position according to the data measured by the top ranging sensor.

[0006] Furthermore, the bottom of the support base is provided with universal movable wheels for facilitating the movement of the equipment, and the sides of the support base are installed with side support columns for facilitating the fixing and supporting of the equipment.

[0007] Furthermore, the lifting mechanism includes a driving wheel, a power motor, a rotating belt, a belt limiting plate, and a driven wheel. The output end of the power motor is mechanically connected to its driving wheel. The outer wall of the driving wheel cooperates with the outer wall of the driven wheel through a rotating belt, and a photo camera is installed on the outer wall of one side of the rotating belt. A belt limiting plate is provided on the side of the rotating belt away from the photo camera.

[0008] Furthermore, the driving wheel, the power motor and the driven wheel are all fixedly mounted on the robot arm main body shell through a support frame, and a limit baffle is installed on the side of the robot arm main body shell close to the belt limit plate.

[0009] Furthermore, a useful movable groove is provided on the main body of the robotic arm.

[0010] Furthermore, the top distance measuring sensor, camera and power motor are all electrically connected to the control mainboard, and the control mainboard is provided with a power supply module.

[0011] The invention discloses a control method for a self-adaptive height-adjustable photographing mechanical arm, which comprises the following operation steps: obtaining current relevant data through a top distance-measuring sensor; calculating the distance that a photographing camera needs to move through a formula; controlling a power motor to operate, and driving a driving wheel and a rotating belt through the power motor; controlling the photographing camera to move to a specified height through the rotating belt; controlling the photographing camera to take photos; giving voice prompts and repeatedly obtaining current relevant data through the top distance-measuring sensor, and repeating this process.

[0012] Furthermore, the data required to be obtained by the top distance measuring sensor is: the distance between the top of the human head and the top distance measuring sensor.

[0013] Furthermore, the calculation formula is: L=H0-(H1-H2), where L is the distance required to be moved, H0 is the current height of the camera, H1 is the longest distance the camera can move, and H2 is the distance between the top of the human head and the top ranging sensor.

[0014] Furthermore, if the calculation result is a positive number, the camera is controlled to move downward; if the calculation result is 0, the position of the camera is kept unchanged; if the calculation result is a negative number, the camera is controlled to move upward.

[0015] After adopting the above technical scheme, the beneficial effect of the present invention is: the photo-taking robot arm can automatically identify the height of the person being photographed, and automatically adjust the relative height position of its photo-taking camera, so that its photo-taking camera can accurately enter the facial information of the person being photographed, which not only ensures its optimal shooting angle, but also does not require manual adjustment, thereby reducing the workload of its staff.

DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 4 As shown, the technical solution adopted in this specific embodiment is: it includes a mechanical arm body 4, a control main board 8 and a lifting mechanism 9 are installed inside the mechanical arm body 4, a photo camera 3 is installed on one side of the lifting mechanism 9, and the photo camera 3 is slidably matched with the shell of the mechanical arm body 4, a top panel 1 is fixedly connected to the top of the mechanical arm body 4, a top distance sensor 2 is provided below the top panel 1, and the bottom of the mechanical arm body 4 is installed on a support base 6, and a standing panel 7 is installed above the support base 6.

[0023] To be more specific, the bottom of the support base 6 is provided with universal movable wheels 5 for facilitating the movement of the device, and the side of the support base 6 is installed with side support columns 601 for facilitating the fixing and supporting of the device.

[0024] More specifically, the lifting mechanism 9 includes a driving wheel 91, a power motor 92, a rotating belt 93, a belt limiting plate 94, and a driven wheel 95. The output end of the power motor 92 is mechanically connected to the driving wheel 91. The outer wall of the driving wheel 91 cooperates with the outer wall of the driven wheel 95 through the rotating belt 93, and the outer wall on one side of the rotating belt 93 is installed with a photo camera 3. A belt limiting plate 94 is provided on the side of the rotating belt 93 away from the photo camera 3. When adjusting the shooting height of the photo camera 3, the power motor 92 will drive the driving wheel 91 to rotate, and through the cooperation between the driving wheel 91 and the driven wheel 95, the rotating belt 93 is driven to move, and the rotating belt 93 is used to drive the photo camera 3 to rise and fall, thereby adjusting the shooting height of the photo camera 3, wherein the belt limiting plate 94 can limit the rotating belt 93, thereby preventing the photo camera 3 from colliding with the housing.

[0025] More specifically, the driving wheel 91, the power motor 92 and the driven wheel 95 are all fixedly mounted on the housing of the mechanical arm body 4 through a support frame, and a limit baffle is installed on the housing of the mechanical arm body 4 near the belt limit plate 94. The limit baffle cooperates with the belt limit plate 94 to limit the rotation of the rotating belt 93.

[0026] More specifically, a useful movable groove 401 is provided on the mechanical arm body 4. The movable groove 401 can facilitate the movement of the camera 3 so that the camera 3 can be quickly adjusted in height.

[0027] More specifically, the top distance measuring sensor 2, the camera 3 and the power motor 92 are all electrically connected to the control mainboard 8, and a power supply module is provided on the control mainboard 8. The top distance measuring sensor 2, the camera 3 and the power motor 92 are controlled by the control mainboard 8, so that the top distance measuring sensor 2, the camera 3 and the power motor 92 can cooperate with each other to complete the photo operation, and the control mainboard 8 provides power supply to the top distance measuring sensor 2, the camera 3 and the power motor 92.

[0028] A control method for a self-adaptive height-adjustable photographing mechanical arm comprises the following steps: S1, obtaining the distance between the top of the human head and the top distance measuring sensor 2 through the top distance measuring sensor 2; S2, calculates the distance that the camera 3 needs to move by the formula, where the calculation formula is: L=H0-(H1-H2), where L is the distance that needs to be moved, H0 is the current height of the camera 3, H1 is the longest distance that the camera 3 can move, and H2 is the distance between the top of the human head and the top ranging sensor 2 (if the calculation result is a positive number, the camera 3 is controlled to move downward; if the calculation result is 0, the position of the camera 3 is kept unchanged; if the calculation result is a negative number, the camera 3 is controlled to move upward).

[0029] S3, controlling the power motor 92 to operate, and driving the driving wheel 91 and the rotating belt 93 through the power motor 92; S4, using the rotating belt 93 to control the camera 3 to move to a specified height; S5, controlling the camera 3 to take photos; S6, give voice prompts and repeat S1, and repeat this process over and over again.

[0030] The working principle of the present invention is as follows: when it is necessary to take pictures and record facial information, the photographing robot arm can be used. When in use, the user only needs to stand on the standing panel 7. At this time, the top distance measuring sensor 2 will detect the distance between the top of the person's head and the top distance measuring sensor 2, and transmit it to the control main board 8. The control main board 8 will control the lifting mechanism 9, and use the lifting mechanism 9 to adjust the shooting height of the camera 3. After adjusting the camera 3, the camera 3 will perform the shooting operation, thereby completing the shooting and recording of facial information. Among them, the staff can move the equipment through the universal moving wheels 5, and support and fix the equipment through the side support columns 601.
