Detecting looming motion directly towards the insect is vital to its survival. Looming detection in two insects, flies and locusts, is described and contrasted. Pathways using looming detectors to trigger action and their topographical layout in the brain is explored in relation to facilitating behavioural selection. Similar visual stimuli, such as looming motion, are processed by nearby glomeruli in the brain. Insect-inspired looming motion detectors are combined to detect and avoid collision in different scenarios by robots, vehicles and UAVs.

3D 世界中昆虫视觉的最新进展：迫在眉睫的刺激和逃避行为

检测直接朝向昆虫的迫近运动对于其生存至关重要。描述并对比了两种昆虫（苍蝇和蝗虫）中迫在眉睫的检测。探索使用迫在眉睫的探测器触发动作的通路及其在大脑中的拓扑布局，以促进行为选择。类似的视觉刺激，例如若隐若现的运动，由大脑中附近的肾小球处理。受昆虫启发的若隐若现的运动探测器相结合，可以检测和避免机器人、车辆和无人机在不同场景下的碰撞。
