Abstract

The invention discloses a prediction needle type camera based on audio frequency orientation and a support adjusting assembly thereof. The prediction needle type camera comprises a positioning seat, a supporting rod rotating shaft seat, a deflection shaft rod assembly, a video recording deflection mechanism and a sound source positioning assembly, wherein the bottom end of the supporting rod rotating shaft seat is movably connected with the surface of the positioning seat; the sound source positioning assembly is fixedly installed on the surface of the video recording deflection mechanism; the two ends of the deflection shaft rod assembly are fixedly connected with one end of the supporting rod rotating shaft seat and one end of the video recording deflection mechanism respectively; a processor is arranged in the sound source positioning assembly; and the supporting rod rotating shaft seat comprises a deflection shaft seat, a bearing bush protection block and a longitudinal deflection seat. According to the prediction needle type camera based on audio frequency orientation, the face position of a person is directed through audio frequency recognition according to the oral sound of a user, the multi-axis linkage structure is automatically controlled according to sound source positioning, and the opposite direction of the camera is adjusted, so that the camera accurately faces the face of the human body and records facial biological information for biological recognition, the structure is simple, the practicability is high, and intelligent tracking identification of the human body can be realized.

Description

technical field [0001] The invention relates to the technical field of camera adjustment, in particular to a predictive needle camera based on audio frequency orientation and a bracket adjustment assembly thereof. Background technique [0002] Micro camera is a product of modern high technology, also known as micro monitor, which has the characteristics of small size, powerful function, good concealment, and is widely used in biometric identification of various anti-theft access control. Biometrics is a technology that uses biological characteristics to identify an individual. Biometric features include fingerprints, hand shapes, retinas, iris, and human faces, as well as human behavioral features such as signatures, voice, and gait. Among these features, the iris has gradually become one of the most unique features because of its uniqueness, stability, and security. Valid biometrics. Iris-based automatic identification and verification systems have become more and more po...

Problems solved by technology

[0003] With the rapid development of computer vision technology, the application of computer vision technology is becoming more and more extensive. Cameras are used to collect images or video streams containing human faces, and automatically detect and track human faces in the images, and then analyze the detected human faces. Perform face recognition, but the range of tracking faces is still limited to the viewfinder range of still cameras. In the process of biometric recognition, the other camera adjusts the angles horizontally and vertically according to the elevation of the person and the position of the face to realize the detection of the human face. Accurate scanning and recognition of biometric features, the angle adjustment procedure is cumbersome, and at the same time, multiple horizontal and vertical angle control devices increase the cost, and the camera cannot be rotated, which actually limits the three-dimensional space of the camera, which greatly affects the camera effect in practical applications. and the current cameras are very short and cannot be extended, but in actual use, this greatly limits the angle of the camera, so the camera effect is extremely bad. If the camera can change in a large range of spatial stereo , the existing camera is absolutely not acceptable

[0004] In addition, in the existing mechanism design for multi-degree-of-freedom motion adjustment of the camera, the driving structure responsible for multiple degrees of freedom is often A telescopic cylindrical metal hose is used to connect, but in this design, although the metal hose itself can be deformed in multiple directions, it can make a good multi-dimensional adjustment and transition, but after the adjustment is in place, it is formally due to the metal hose Due to its own deformability, external forces, especially accidental forces, such as accidental collisions of limbs, or accidental contact with the user's posture adjustment during the process of taking avatars, will make the original adjusted optical lens undesired. deflection, thereby making the inevitable repeated adjustments

In addition, the direction of some optical lenses is relatively special, and the driving structure on both sides of the metal hose needs to be offset to a large extent, so that the center of gravity of the adjustment structure where the entire metal hose is located changes greatly, so that after the adjustment is in place, the entire camera The cast cannot get a stable support, even if it is barely static and can maintain its posture, it will shake violently after receiving an external force, which further aggravates the difficulty of repeated adjustments

[0005] In view of this, the existing problems are studied and improved, and a predictive needle camera and its bracket adjustment components based on audio frequency orientation are provided to solve the current problem that the existing camera cannot be oriented to identify motion tracking. Through this technology, To achieve the purpose of solving problems and improving practical value
