Vision is an important sensory modality for navigation in roaming animals. In contrast to most vertebrates, insects usually must cope with low resolution retinal images and the inability to infer spatial features using accommodation or stereovision. However, during locomotion, the retinal input is dominated by characteristic panoramic image shifts, termed optic flow, that depend on self-motion parameters and environmental features. Therefore, optic flow provides a rich source of information guiding locomotion speed as well as the position and orientation of animals over time relative to their surroundings. Here, focusing on flight behavior, we describe the strategies and putative underlying neuronal mechanisms by which insects control their course through processing of visual motion cues.

昆虫中基于光流的过程控制。

视觉是漫游动物航行时的重要感觉方式。与大多数脊椎动物相反，昆虫通常必须应对低分辨率的视网膜图像以及无法通过调节或立体视觉来推断空间特征。然而，在运动过程中，视网膜输入受特征性全景图像位移（称为光流）的控制，该位移取决于自运动参数和环境特征。因此，光流提供了丰富的信息来指导运动速度以及动物相对于周围环境随时间的位置和方向。在这里，着重于飞行行为，我们描述了昆虫通过视觉运动线索的处理控制其进程的策略和潜在的潜在神经元机制。
