## 3 Experiment Validation and Analysis
### Experiment and Analysis of Glare Suppression for Orientation Information  
The experimental setup for glare suppression using real-time orientation calculation is shown in Figure 11. This setup includes a Daheng Mercury second-generation MERCURY2 polarization camera, a halogen light source with polarization characteristics, and an MEMS inertial sensor. The MEMS inertial sensor is placed indoors to simulate a fluctuating sea surface. Using the real-time orientation information calculation method provided in Section 2.2.2, the orientation information of sea surface fluctuations is obtained. This orientation information is used to compensate for the impact of sea surface fluctuations on the monitoring platform. During the experiment, the glare polarization angles before and after orientation information compensation under the same light incidence angles are recorded. The relationship curves between incidence angles and polarization angles before and after orientation information compensation are shown in Figure 12, and the fitted experimental data are presented in Table 4. \begin{table}

Table 3: Real-time positioning glare suppression experimental relative error. We compared the polarization angles for the same incidence angles in Table 4 with those in Table 1, and calculated the relative error of the experimental data in Table 4 with respect to Table 1. The results of the relative error calculation are presented in Table 5.  
As shown in Figure 12, in the experiment of glare suppression using real-time orientation information, the relationship curve between the incidence angles and the glare polarization angles exhibits a pattern similar to the correlation observed in Figure 8. According to Table 5, the average relative error of the glare polarization angles before orientation information compensation is 4.12%. After orientation information compensation, the average relative error of the glare polarization angles decreases to 1.70%. Therefore, there is
