Haze-degraded image full-polarization sharpening device

Abstract

The invention discloses a haze-degraded image full-polarization sharpening device. A method for actively transmitting light beam including circular polarization information is adopted; the circular polarization information is acquired by a high-definition camera module, and transmitted to a computer terminal through a data line; therefore, the situation that the circular polarization information in target reflected light is difficultly acquired is broken; then, according to an atmospheric physical attenuation model, the computer terminal solves a sharp image by utilizing the Stokes vector detection principle according to unknown parameters in a dark-channel prior knowledge estimation model; the haze-degraded image full-polarization sharpening device is mainly composed of an LED lamp outgoing device, a synchronous adjustment mechanism, a polarizer frame, the high-definition camera module and the computer terminal; the LED lamp outgoing device is connected outside the whole image acquisition device through threaded connection; the polarizer frame sleeves outside the high-definition camera module; the high-definition camera module is connected to the synchronous adjustment claw of the synchronous adjustment mechanism; the image information acquisition angle can be adjusted; the high-definition camera module is connected with the computer terminal through a data line; and data information is provided for defogging treatment.

Description

technical field [0001] The invention relates to a full polarization image information acquisition device. Background technique [0002] The acquisition of polarization image information plays an important role in atmospheric polarization model testing and weather degradation image restoration methods based on physical models. Polarization defogging technology is mostly based on linear polarization information, and the polarization information of light is generally described by Stokes vectors (I, Q, U, V). Since circularly polarized light is difficult to obtain, current polarization defogging methods based on physical models mostly make V=0, process the image containing polarization information to solve the polarization parameters I, Q, U, estimate the ambient light value and atmospheric polarization degree, and then invert the model to realize dehazing. Studies have shown that circularly polarized light has more potential advantages than linearly polarized light, especially...
