Field Environment Sky Polarization Modeling Alignment Measurement Device

Abstract

The field environment sky polarization modeling alignment measurement device provides a direction reference and detects sky polarization patterns in complex environments. The device consists of a polarization image measurement module, a rotation drive module, a laser marking module, a platform alignment module, and a user control and processing module. During detection, the platform alignment module aligns the imaging optical axis with the central axis of the laser marking instrument; based on the laser marking module, the reference direction of the device is aligned with the external reference vector measured by GPS, and the sky polarization image is obtained. Direction reference; the user control and processing module transmits user instructions, so that the rotation drive module controls the polarizer to rotate in an orderly manner, and adjusts the polarization state of the camera input light; at the same time, the polarization image measurement module measures polarization image information. The device and detection method are suitable for detecting the sky polarization mode in a complex field environment, and provide a reliable direction reference for sky polarization modeling.

Description

technical field [0001] The invention relates to the field of sky polarization modeling research and intelligent information acquisition, in particular to a field environment sky polarization modeling alignment measurement device, which provides a modeling basis for bionic polarization navigation. Background technique [0002] When sunlight radiates through the atmosphere, it will scatter and absorb with atmospheric particles, forming a polarization field with a specific distribution pattern throughout the sky, which contains spatial information rules and is used for bionic polarization navigation. At present, the establishment of sky polarization models is usually based on the Rayleigh scattering theory, which is suitable for clear and cloudless weather conditions, but is not applicable in complex weather such as cloudy, fog, and haze. Therefore, the establishment of a polarization model for environmental adaptation is one of the important issues to be solved in the study of...
