Description

Technical Field

[0001] The present invention relates to the technical field of bracket equipment, and in particular to an adjustable bracket suitable for a photographing device and a use method thereof. Background Art

[0002] In the fields of industrial production, product inspection, traffic security, elevator control, outdoor monitoring, etc., video and picture shooting and recognition are important auxiliary means, and in order to better install the shooting device, it is generally necessary to use an external bracket for fixed connection. The existing bracket system is generally a fixed structure, which has the advantages of being relatively stable and low cost, but it cannot adapt to some environments where the position needs to be adjusted, especially in the process. The environment where the height and left and right position need to be adjusted frequently, such as elevator control, dormitory access control and other environments that require face recognition, there are many inconveniences for people of different heights, disabled people who need to use wheelchairs, people with neck injuries who cannot raise their heads, people with waist and leg injuries who are inconvenient to bend, etc., and they need to retreat to a longer distance. However, at this time, if the camera clarity or light cannot meet the requirements, or in a small space such as an elevator, corridor access control, etc., when the retreat distance cannot be provided, external personnel are often required to assist in real-time adjustment of the shooting device to achieve control and recognition.

With this design, the entire bracket body 1 can be directly erected in an unsupported environment on flat ground, so that it can be used in more scenarios, such as open scenarios such as venue security doors.

[0060] Attached Fig.12 and Fig.13 This is just an example. According to actual needs, the length of the bottom support mechanism groove 102 can be larger than the proportion shown in the figure, so as to meet a wider range of support requirements. When necessary, threaded holes can be set on the sides of the two main support bars 801 and the secondary support bar 802, and a structure similar to the cross bar of the bracket body 1 can be separately connected to increase the stability of the entire bracket body 1.

[0061] Embodiment 6: Based on Embodiment 5, adhesives or magnetics are provided on the back and outer side of the bracket body 1. Such a design is mainly used in certain use environments, such as elevators, etc. When the elevator needs to be controlled so that different users need to go to different floors, the adhesives (such as stickers) or magnetics can be attached and fixed to the inner wall of the elevator car. At this time, the bottom support mechanism 8 does not need to be opened, and the bracket can be fixed, and the internal space can be better occupied. It has excellent adaptability to relatively small areas such as elevator cars, and is convenient for adjustment to elevator cars of different sizes, such as freight elevators and passenger elevators.

[0062] Embodiment 7: A method for using an adjustable bracket for a photographing device, using the adjustable bracket for a photographing device of the aforementioned embodiment 6, comprising the following steps:

[0063] Step 1: According to the required higher position of conventional height (such as the elevator door area, set to a height of 1.8-2.2m), install the auxiliary bracket plate 2 to the quick-release fixing hole 101 of the bracket body 1, and fix the telescopic support rod 3, then install the shooting device 4 and ensure that the whole is powered on, and then adjust the angle of the damping universal joint 4051 according to the general angle (such as keeping the horizontal angle, or tilting downward 10-30°) to ensure that the shooting angle is appropriate;

[0064] In step 1, firstly, the installation method and size need to be designed according to the required environment. For example, if it is used in an elevator, there is no need to open the bottom support mechanism 8. After adjusting the bracket body 1, the entire bracket body 1 can be installed to the inner side of the elevator door directly by fitting or magnetic attraction; and the position of the shooting device 4 is set according to the use environment. For example, if it is used in an elevator, the telescopic support rod 3 generally needs to be placed on the far right. If it is used on a product assembly line, it is more appropriate to place it in the middle.

[0065] Step 2: Install the bracket body 1 to the desired position, and choose whether to open the bottom support mechanism 8 and the auxiliary support bar 802 according to the nature of the position;

[0066] In step 2, generally for use on an open flat ground, after the bottom support mechanism 8 is opened and fixed, the secondary support bar 802 is opened, so that the entire support body 1 can be fixed without the help of external force, achieving a fixing effect, and the structure is simple, which is easy to install and recycle;

[0067] Step 3: When the user is using the camera, if there is no need to adjust the height and left and right position of the camera, the user can directly adjust the height and left and right position of the camera through the bracket body 1; if the left and right position of the camera needs to be adjusted, the user can adjust the left and right position by pulling the horizontal adjustment rope 9; if the height of the camera needs to be adjusted, the user can lower or return the secondary telescopic rod 302 through the telescopic rod rope 303;

[0068] In step 3, the specific operations are as follows:

[0069] Step 301, when the height of the camera device cannot recognize a human face, for example, if the height of the user is lower than that of the camera device, the user manually operates the telescopic rod pull rope 303, and at this time the release rod 3012 is lifted upward and separated from the primary fixing slot, so that the secondary telescopic rod 302 is freed from restraint and moves downward slowly, and the human face can be photographed in the process to achieve recognition; if necessary, the damping universal joint 4051 can also be manually adjusted to achieve the required shooting angle;

[0070] When the left and right positions of the camera device cannot recognize a human face, in addition to the person's active left and right movement, if there are many people or people and goods are mixed, and it is inconvenient for people to move, the horizontal sleeve pull rope 9 can be pulled to allow the first-level telescopic rod 301 to be pushed into place by the horizontal sleeve pull rope 9 under manual operation. If it needs to be returned to its original position after use, the recovery pull rope 7 is pulled again. The recovery pull rope allows the retractable drum 6 to start rotating to retract the horizontal sleeve pull rope 9 after receiving the instruction, so that the entire first-level telescopic rod 301 is returned to its original position, and the entire horizontal area is photographed and recognized during the process;

[0071] Step 4: When the camera 402 is contaminated, adjust the lens cleaning strip 401 to move left and right to wipe the surface of the camera 402 to keep it clean;

[0072] This operation can be completed through the built-in algorithm of camera 402, or through manual operation of the control system. Especially in areas with large traffic flow, due to the influence of dust, oil smoke, etc., the camera 402 needs to be cleaned from time to time. The existing technology generally requires manual adjustment of the bracket and manual erasing. The present solution can be combined with the power supply of the bracket body 1 itself to achieve relatively convenient cleaning.

[0073] In summary, the present invention can be used in environments where people or goods are photographed in a variety of scenarios, such as elevator control, access control identification, crowd counting, and goods circulation. Taking elevator control as an example, in a confidential unit environment that requires elevator control, such as the core floor area of ​​a research and development institution, it is necessary to limit the floor control authority of other people. When some authorized staff members have damaged lumbar or cervical vertebrae and cannot bend over or lower their heads, and there are no assistants around to help with the operation, if face recognition in the elevator is needed, the present invention can be used to complete the recognition by itself. Similarly, in the case of goods circulation, when it is necessary to photograph and identify items of different sizes, the up, down, left, and right positions and angles of the shooting device 4 can be adjusted to achieve relevant shooting to avoid poor shooting positions or obstacles to logistics transportation.
