Processing Technology for Bioinspired Polarization Compass Noise

According to the static and dynamic test results for the bioinspired polarization compass, the heading accuracy is seriously affected by the compass noise. This noise comes not only from the AoP image acquired by the compass polarization image sensor, but also from the compass circuit. Therefore, this chapter concentrates the noise analysis and denoising methods for the bioinspired polarization compass. Firstly, different types of noise and their generation mechanism of the bioinspired polarization compass are explored and the noise characteristics are analyzed. Secondly, the denoising algorithm based on Multi-scale Transform (MST) is presented for the bioinspired polarization compass. Finally, the denoising methods for AoP image and heading angle data in significantly improving the orientation accuracy of the polarization compass are verified and analyzed in detail in the way of various experiments.
