Description

Technical Field

[0001] The utility model relates to the technical field of image acquisition, in particular to an AI dynamic image acquisition device. Background Art

[0002] The AI ​​dynamic image acquisition device is a technical device designed specifically for capturing computer screen content. Its main uses include monitoring security, education and training, user behavior analysis, and software development and testing. Its core structure includes a high-definition camera, a data transmission interface, an image processing unit, a back-end analysis system, and a data storage device. The image acquisition camera is the core component of the device, usually a high-definition camera that is used to capture images on the computer screen in real time. It transmits the captured image data to the back-end processing system. Before the data is transmitted to the back-end, some preliminary image processing is usually performed, such as denoising, contrast enhancement, etc., to improve the accuracy and efficiency of subsequent analysis. The back-end analysis system receives and processes the image data transmitted from the camera;

[0003] For example, the AI ​​dynamic image acquisition device and image acquisition system disclosed in the authorization announcement number CN208386763U include: a lens, an image sensor and a USB2.0 control module; the center of the photosensitive matrix of the image sensor is opposite to the focusing center of the lens; the FIFO memory of the USB2.0 control module is electrically connected to the image sensor, the FIFO memory is electrically connected to the 8051 core of the USB2.0 control module, the 8051 core is electrically connected to the RAM of the USB2.0 control module, and is also electrically connected to the serial interface engine of the USB2.0 control module. By directly processing the image collected by the image sensor, the processing link of the FPGA module is omitted. However, this technical solution still needs to use a camera to cooperate in image acquisition of the computer screen display screen. Therefore, the camera needs to be set up in front of the screen using structures such as a tripod and a bracket, and the use of the tripod and the bracket occupies a large space area. In places such as offices or classrooms, the space is often limited. When multiple screens or multiple angles need to be covered, more cameras and brackets mean more space occupation, and additional installation and wiring work may be required, increasing the overall complexity and cost.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5The utility model provides an embodiment: an AI dynamic image acquisition device, comprising an inverted U-shaped frame 1 and a U-shaped card holder 4 installed on one side of the back of the inverted U-shaped frame 1, wherein the inverted U-shaped frame 1 and the U-shaped card holder 4 are both made of hard plastic material, which is usually lighter than metal material, and can reduce the weight of the overall component;

[0020] A screw clamping structure 5 for pressing against the upper frame of the screen is installed inside the U-shaped card holder 4, a right-angle slider 2 is slidably installed on the front and rear outer walls of the inverted U-shaped frame 1, a front H-shaped frame 6 is arranged on one side of the inverted U-shaped frame 1, a connecting rod swing lifting structure 7 that can swing relative to each other is installed between the front H-shaped frame 6 and the right-angle slider 2, a screw lifting structure 3 for controlling the height of the right-angle slider 2 is installed inside the inverted U-shaped frame 1, an angle adjustment structure is installed at the bottom end of the front H-shaped frame 6, and an image acquisition camera 10 is installed at the bottom end of the front H-shaped frame 6 through the angle adjustment structure;

[0021] The screw clamping structure 5 includes a threaded shaft 501 rotatably mounted on the outer wall of one side of the U-shaped card holder 4, and a rubber disc 502 fixed at the top of the threaded shaft 501. In the process of fixing and limiting the device, the U-shaped card holder 4 is clamped on the upper frame of the screen, and the staff continuously rotates the threaded shaft 501, so that the threaded shaft 501 drives the rubber disc 502 to approach the back of the screen until the U-shaped card holder 4 is pressed against the screen frame, so as to ensure the position of the device is stable, and the installation process is simpler and faster;

[0022] The screw lifting structure 3 includes a knob rotatably mounted on the top of the inverted U-shaped frame 1 and a screw rotatably mounted inside the inverted U-shaped frame 1. The top of the screw is fixedly connected to the bottom of the knob. A nut pair is installed at a threaded portion at one end of the screw surface. One side outer wall of the nut pair and one side outer wall of the right-angle slider 2 are connected to each other through a straight plate. Straight grooves for the straight plate to slide are provided on the front and rear outer walls of the inverted U-shaped frame 1.

[0023] The connecting rod swing-up structure 7 includes a connecting rod monomer 702 hingedly mounted on the outer wall of one side of the right-angle slider 2 and two elastic telescopic arms 701 hingedly mounted on the front and rear outer walls of the inverted U-shaped frame 1. The bottom end of the connecting rod monomer 702 is hingedly connected to the outer wall of one side of the front H-shaped frame 6, and the end of the elastic telescopic arm 701 away from the inverted U-shaped frame 1 is hingedly connected to the outer wall of one side of the front H-shaped frame 6. By screwing the knob at the top of the inverted U-shaped frame 1, the knob drives the screw rod to rotate, and then the screw rod drives the nut pair and the right-angle slider 2 to move downward. The ends of the connecting rod monomer 702 are respectively hingedly mounted on the outer wall of the same side of the right-angle slider 2 and the screw lifting structure 3, and the right-angle slider 2 forces the front H-shaped frame 6 and the elastic telescopic arm 701 to swing downward through the connecting rod monomer 702 until the lens of the image acquisition camera 10 moves down to a reasonable position to ensure that it can capture the dynamic image on the screen. Through simple lifting or swinging operations, the height and angle of the camera can be quickly adjusted to optimize the capture of the content on the screen without re-adjusting the entire supporting structure;

[0024] The angle adjustment knot includes an inverted T-shaped seat 8 fixed to the bottom end of the front H-shaped frame 6, and a clamp 9 hingedly installed at the bottom end of the inverted T-shaped seat 8. The lens of the image acquisition camera 10 is fixed inside the clamp 9. The image acquisition camera 10 is manually rotated so that the image acquisition camera 10 drives the clamp 9 and adjusts the angle with the inverted T-shaped seat 8 as the central axis, so that the lens of the image acquisition camera 10 faces the screen at a suitable angle.

[0025] When the embodiment of the present application is in use, the staff first takes out the device, and sets the inverted U-shaped frame 1 on the upper frame of the screen to be used for capturing dynamic images through the U-shaped holder 4 and the screw clamping structure 5, and uses the screw clamping structure 5 to firmly clamp the U-shaped holder 4 on the upper frame of the screen. Then the staff adjusts the height and angle of the image acquisition camera 10. During this process, the staff manually operates the screw lifting structure 3, and the screw lifting structure 3 drives the right-angle slider 2 to slide down. Since the front H-shaped frame 6 is connected to the inverted U-shaped frame 1 and the right-angle slider 2 through the connecting rod swing lifting structure 7, the sliding movement of the right-angle slider 2 is converted into a swinging downward movement or a swinging upward movement of the front H-shaped frame 6 through the connecting rod swing lifting structure 7. Lifting action, after the relative heights of the current H-shaped frame 6, the image acquisition camera 10 and the screen are adjusted, the staff manually rotates the image acquisition camera 10, so that the image acquisition camera 10 drives the clamp 9 and adjusts the angle with the inverted T-shaped seat 8 as the central axis, so that the lens of the image acquisition camera 10 is facing the screen at a suitable height and angle, so as to capture the screen content. The device directly installs the camera on the upper frame of the display screen without the need for additional supporting equipment, greatly saving desktop space and making the overall layout of the space more concise, especially when multiple screens or multiple pictures are required to acquire images simultaneously, effectively reducing the space occupancy range.
