This paper explores the influence of various camera settings on the quality of 3D reconstructions, particularly in indoor crime scene investigations. Utilizing Neural Radiance Fields (NeRF) and Gaussian Splatting for 3D reconstruction, we analyzed the impact of ISO, shutter speed, and aperture settings on the quality of the resulting 3D reconstructions. By conducting controlled experiments in a meeting room setup, we identified optimal settings that minimize noise and artifacts while maximizing detail and brightness. Our findings indicate that an ISO of 200, a shutter speed of 1/60 s, and an aperture of f/3.5 provide the best balance for high-quality 3D reconstructions. These settings are especially useful for forensic applications, architectural visualization, and cultural heritage preservation, offering practical guidelines for professionals in these fields. The study also highlights the potential for future research to expand on these findings by exploring other camera parameters and real-time adjustment techniques.
本文探讨了各种相机设置对三维重建质量的影响，特别是在室内犯罪现场调查中。利用神经辐射场（NeRF）和高斯点渲染进行三维重建，我们分析了感光度、快门速度和光圈设置对所得三维重建质量的影响。通过在会议室环境中进行对照实验，我们确定了能在最大限度减少噪声和伪影的同时，最大化细节和亮度的最佳设置。我们的研究结果表明，感光度为200、快门速度为1/60秒、光圈为f/3.5能为高质量三维重建提供最佳平衡。这些设置对法医应用、建筑可视化和文化遗产保护特别有用，为这些领域的专业人员提供了实用指南。该研究还强调了未来研究通过探索其他相机参数和实时调整技术来扩展这些发现的潜力。
