## 3 Experiment Validation and Analysis  
To validate the effectiveness of the proposed method, a series of experiments were conducted, including experiments on real-time positioning information glare suppression and real-time orientation calculation glare suppression methods, as well as glare suppression experiments using the geographic polarization model. The results of these experiments were analyzed to confirm the feasibility and effectiveness of the proposed algorithm.  
The experimental setup for measuring the relationship between the light incidence angle and the glare polarization angle is shown in Figure 7. A halogen light source with polarization characteristics was used to simulate sunlight for illumination [25; 26; 27], and the glare was captured using the Daheng Mercury second-generation China MERCURY2 polarization camera (Beijing, China). Based on the polarization images obtained from four directions using the polarization camera, the Stokes vector S was calculated, from which the angle of polarization (AOP) of the glare was determined. The calculation formulas are shown in Equations (21) and (22). The experiment covered the relationships between different light incidence angles and the polarization degree angle of glare, with the results shown in Figure 8. By fitting these experimental data, the experimental data in Table 1 were obtained.  
\[S=\begin{bmatrix}S_{0}\\ S_{1}\\ S_{2}\\ S_{3}\end{bmatrix}=\begin{bmatrix}I_{0}+I_{90}\\ I_{0}-I_{90}\\ I_{45}-I_{135}\\ I_{L}-I_{R}\end{bmatrix} \tag{21}\]

\[AOP=\frac{1}{2}\arctan\left(\frac{S_{2}}{S_{1}}\right) \tag{22}\]  
In this study, the original experimental data were subjected to smoothing and fitting processing. As can be observed from Figure 8, there is a distinct incident-polarization relationship between the light incidence angle and the glare's polarization angle in the fitted polarization angle curve. This relationship is of significant importance for the glare suppression method.

The data from Figure 8 and Table 1 are used as benchmark data, which are then compared with the experimental data collected in Sections 3.1-3.3. By calculating the error in the experimental data, the effectiveness of the identified incident-polarization relationship for glare suppression is verified.
