Real-time synchronous acquisition device for image type sky polarized light distribution modes

Abstract

The invention relates to the technical field of navigation and positioning, in particular to a real-time synchronous acquisition device for image type sky polarized light distribution modes. The acquisition device comprises three cameras with linear polaroids, and a computer processing system, wherein the cameras are provided with independent kilomega network ports, and connected in the computer processing system by exchangers; the exchangers perform IP (Internet Protocol) address setting and serial number distribution; the cameras are arranged on mechanical supporting frames; central axes of lenses of the cameras are parallel; projections of the three central axes in a vertical plane form an equilateral triangle; the side length d of the equilateral triangle is obtained by the following calculation formula as shown in the specification; the three cameras are connected with the three prime lens respectively; the prime lens are equipped with the linear polaroids; and polarization polarity angles of the linear polaroids satisfy the following formula: alpha 1 is greater than or equal to 0 degree and less than alpha 2, and alpha 3 is greater than alpha 2 and less than 180 degrees. The acquisition device can acquire an overlapped part of public areas shot by the three cameras, the area displays polarization degree and polarization angle information, real-time synchronous acquisition of the polarization information is realized. The acquisition device is simple in structure, convenient to process, good in real-time synchronization, and higher in practicability.

Description

technical field [0001] The invention relates to the technical field of navigation and positioning, in particular to an image-based real-time synchronous acquisition device for polarized light distribution patterns in the sky. Background technique [0002] The distribution pattern of polarized light in the sky is relatively stable, and animals such as sand ants and bees can use polarized light for orientation and navigation. Inspired by the ability of these animals to use polarized light to orient themselves, researchers have conducted research on the distribution of polarized light in the sky and polarization-based navigation methods, and have gradually begun to apply polarized light bionic navigation methods to mobile robots, ships, and aircraft Various moving objects in the atmosphere. Therefore, the acquisition of polarized light distribution pattern in the sky is of great significance for the method of bionic navigation using polarized light. [0003] At present, domes...

Problems solved by technology

Since this method cannot be collected synchronously in real time, rotating the linear polarizer will inevitably bring time delay and hysteresis, resulting in the polarization distribution pattern obtained by calculation and synthesis is not from the sky polarization image picture at the same time, while rotating the angle of the polarizer Inaccurate will also bring errors
