近年来积累了大量证据，表明导航昆虫在何种程度上依赖于路径整合或地标指导时，流离失所取决于其特定栖息地的导航信息内容。因此，有必要量化这一信息内容。在这里，我们提出了一种实现这一目标的方法，通过使用激光扫描仪和纯粹基于相机的方法构建自然环境的3D模型，使我们能够在任何位置渲染全景。我们提供（1）地面实况重建的意见，对全景图像记录在相同的位置;（2）他们的潜力，以映射自然栖息地的导航信息内容的证据;（3）方法，这些模型与GPS或立体摄像机记录和（4）他们的使用在重建的视觉信息提供给步行和飞行昆虫的例子。我们讨论了目前的3D建模的局限性，包括缺乏光谱和偏振信息，但也有机会，这些模型提供地图的自然栖息地的导航信息内容，并在“现实生活”的条件下测试视觉导航算法。
Much evidence has accumulated in recent years, demonstrating that the degree to which navigating insects rely on path integration or landmark guidance when displaced depends on the navigational information content of their specific habitat. There is thus a need to quantify this information content. Here we present one way of achieving this by constructing 3D models of natural environments using a laser scanner and purely camera-based methods that allow us to render panoramic views at any location. We provide (1) ground-truthing of such reconstructed views against panoramic images recorded at the same locations; (2) evidence of their potential to map the navigational information content of natural habitats; (3) methods to register these models with GPS or with stereo camera recordings and (4) examples of their use in reconstructing the visual information available to walking and flying insects. We discuss the current limitations of 3D modelling, including the lack of spectral and polarisation information, but also the opportunities such models offer to map the navigational information content of natural habitats and to test visual navigation algorithms under 'real-life' conditions.
