立体摄像是一种用于量化动物运动学和行为的强大技术，但在户外环境中使用可能具有挑战性。我们在这里提出了一种工作流程和相关软件，用于执行放置在现场环境中的摄像机的校准，并估计所产生的立体重建的精度。我们通过蝙蝠和鸟儿飞行的实例立体重建演示了工作流程。我们提供用于计划实验和处理结果校准的软件工具，其他研究人员可以使用这些工具来校准他们自己的相机。我们的现场协议可以在一个下午部署，只需要轻便的校准对象的短视频剪辑。
Stereo videography is a powerful technique for quantifying the kinematics and behavior of animals, but it can be challenging to use in an outdoor field setting. We here present a workflow and associated software for performing calibration of cameras placed in a field setting and estimating the accuracy of the resulting stereoscopic reconstructions. We demonstrate the workflow through example stereoscopic reconstructions of bat and bird flight. We provide software tools for planning experiments and processing the resulting calibrations that other researchers may use to calibrate their own cameras. Our field protocol can be deployed in a single afternoon, requiring only short video clips of light, portable calibration objects.
