Description

Technical Field

[0001] The utility model relates to the technical field of camera equipment, in particular to a camera with adjustable polarizing plate. Background Art

[0002] As we all know, light is a transverse wave whose plane of vibration is perpendicular to its propagation direction. It possesses numerous properties, including propagation direction, intensity, and wavelength. Furthermore, light possesses a remarkable property: polarization. Due to the physiological limitations of the human eye, the naked eye cannot perceive the polarization properties of light without the aid of optical devices. However, many compound-eyed insects in nature, such as bees, ants, dragonflies, crickets, and longhorn beetles, are masters of utilizing polarized light. They use the distribution of polarized light in the sky to navigate. Recognizing the importance of polarization, and hoping to enable compound-eyed insects to see polarized light, researchers developed specialized polarization imaging devices, known as polarization cameras. Compared to traditional imaging technologies, these cameras provide additional polarization information, expanding the information content from the three degrees of freedom (intensity, spectrum, and spatial) to seven degrees of freedom (DOP), including polarization degree, polarization azimuth, polarization ellipticity, and rotational orientation. Polarization cameras are widely used in civilian applications.

[0003] The problem with existing polarization cameras is that under certain light angles during shooting, exposure or white light will appear on the screen, which often leads to poor shooting effects and requires manual adjustment of the angle of the polarizer, which is very inconvenient. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art and provide a camera with an adjustable polarizer, so that the lens can be automatically extended and rotated, and the internal polarizer rotates synchronously to achieve the shooting of light at different angles and improve the picture effect of the camera.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is as follows:

[0006] A polarizing camera with adjustable orientation includes a housing, a lens body, and a lens mount within the housing. The housing includes a camera housing and a protective front cover, with a lens channel disposed in the center of the protective front cover. The lens body is provided with a polarizing film, and a plurality of spiral guide grooves are evenly spaced along its outer wall. A drive motor is mounted on the top of the lens mount, with a driving gear disposed at its output end. A ring gear meshing with the driving gear is disposed on the front of the lens mount, and a guide block corresponding to the spiral guide groove is disposed within the ring gear. The lens body is the lens of the polarizing camera, and the lens channel allows the lens body to pass through. The operation of the drive motor drives the driving gear to rotate, which in turn rotates the ring gear. The guide block moves along the spiral guide groove, causing the lens body to produce a telescopic and rotating motion, thereby causing the polarizing film to rotate synchronously.

[0007] Preferably, protective baffles are provided on the upper parts of both sides and the top of the shell, and limiting slots are provided on both sides of the camera cabin. The two sides of the protective baffles are recessed inward to form limiting strips corresponding to the limiting slots. The protective baffles have the function of preventing rainwater and the like from falling onto the shell and the lens.

[0008] Preferably, the front end of the protective baffle exceeds the end surface of the protective front cover.

[0009] Preferably, a plurality of support blocks are evenly arranged on the inner wall of the lens channel of the protective front cover, and the ends of the support blocks are in contact with the outer wall of the lens body. The support blocks allow the lens body to always maintain the same central axis during movement.

[0010] Preferably, a radiator and a control circuit board A are provided on the rear side of the lens mounting frame for controlling the cooling and heat dissipation of the circuit board A and the like.

[0011] Preferably, the radiator is a fan.

[0012] Preferably, mounting posts are provided on the top of the lens mounting brackets on both sides of the driving motor, and a control circuit board B is provided on the top of the mounting posts.

[0013] The advantages of the present invention are that the structural design of the present invention allows the lens to automatically extend and rotate, and the internal polarizer rotates synchronously, so as to achieve the shooting of light at different angles and improve the picture effect of the camera shooting.
