Description

Technical Field

[0001] The utility model belongs to the technical field of vision acquisition, and in particular relates to a positioning structure of a vision acquisition camera. Background Art

[0002] A visual acquisition camera is a device used to capture images or videos. It consists of an image sensor, a lens, an image processor, and an interface. The main function of a visual acquisition camera is to convert images in the real world into digital signals for processing by computers or other devices. Visual acquisition cameras can be used in scenarios such as video calls, video conferencing, and remote monitoring to achieve real-time visual communication between people. Visual acquisition cameras can capture real-time images, enabling computers to recognize and analyze objects, faces, text, etc. in images, and are widely used in face recognition, object detection, image search, and other fields. Visual acquisition cameras can be used for real-time monitoring and recording, and are used in security fields, such as monitoring public places, home security, etc. Visual acquisition cameras can capture users' real-time actions and environmental information for virtual reality and augmented reality applications, such as games, immersive experiences, etc. Visual acquisition cameras can shoot high-definition videos and photos for personal photography and professional photography. In short, visual acquisition cameras play an important role in various fields, enabling computers and other devices to process and understand visual information by capturing images and videos.

[0003] The visual acquisition camera can be focused by light entering the camera through the lens and then focusing through the lens system. The lens system focuses the light onto the image sensor, which is the core component of the visual acquisition camera and usually adopts CMOS or CCD technology. When light is irradiated on the image sensor, each pixel will generate a corresponding electrical signal according to the intensity of the light. After the image sensor converts the light signal into an electrical signal, it converts the analog signal into a digital signal through an analog-to-digital converter (ADC). These digital signals represent the brightness and color information of the image. The collected digital images can be subjected to a series of image processing operations, such as denoising, enhancement, color correction, etc. These image processing operations can improve the image quality and accuracy, and the processed image data is transmitted to a computer or other device through an interface. Common interfaces include USB, HDMI, network interface, etc. The computer or device that receives the image data can display the image, and the user can watch the image in real time. At the same time, the image can also be stored for subsequent analysis or playback. In general, the visual acquisition camera converts the light in the real world into a digital image through optical imaging, image sensors, signal conversion and image processing, and transmits it to a computer or other device through an interface for display and storage. The problem with the above technology is that the visual acquisition camera needs to be supported and positioned by a back plate during installation, but when the visual acquisition camera is assembled with the back plate, multiple connectors and fixings are required for assembly and fixing. The assembly process requires the user to spend a long time and energy. Therefore, there is a problem that the assembly process of the visual acquisition camera and the back plate is relatively cumbersome, and it is not convenient for the user to quickly position and install the visual acquisition camera.

[0023] The working principle of this utility model:

[0024] When in use, the transmission rod 804 is pressed to move according to the opening trajectory of the movable hole 15, and the transmission rod 804 will drive the movable block 801 to move during the movement. When the movable block 801 moves, it will stretch the tension spring 803 and drive the traction rods 802 on both sides to move.
