Photogrammetry is a method for obtaining virtual 3D models of objects and scenes. The technique is increasingly used to record the crime scene in its original, undisturbed state for mapping, analytical and reconstruction purposes. Recently, it was shown that it is possible to visualize and/or chemically analyze latent traces by using advanced cameras which either operate in wavelength ranges beyond the visible range, and/or are able to obtain spectrally resolved images. The combination of these advanced cameras and photogrammetric techniques enables the 3D registration of valuable information. We successfully explored the feasibility to obtain visible, infrared, hyperspectral and thermal 3D registrations of simulated crime scenes using photogrammetry, and demonstrate the possibilities and practical challenges for use in forensic practice.
摄影测量法是一种获取物体和场景虚拟三维模型的方法。该技术越来越多地用于记录原始、未受干扰状态的犯罪现场，以进行绘图、分析和重建。最近的研究表明，使用工作在可见光范围之外的波长范围，和/或能够获得光谱分辨图像的先进相机，可以可视化和/或化学分析潜在痕迹。这些先进相机与摄影测量技术的结合，能够对有价值的信息进行三维配准。我们成功探索了使用摄影测量法对模拟犯罪现场进行可见光、红外、高光谱和热三维配准的可行性，并展示了在法医实践中应用的可能性和实际挑战。
