摘要
自然界中的鹰眼具有视觉敏锐和大视野等优点,可为视觉信息处理技术提供借鉴.本文首先对比了鹰眼和其他类型眼睛之间的不同,介绍了生物学中鹰眼的研究现状;其次,对鹰眼的双中央凹、视觉敏锐度,鹰的对数螺旋运动以及视觉注意机制等仿鹰眼技术进行了阐述,介绍了仿鹰眼视觉技术的典型应用,包括感兴趣目标提取、动态目标跟踪、大视场相机、高分辨率器件以及自动调焦;最后,对仿鹰眼视觉技术的未来研究方向进行了展望.
Eagle-eye has the characteristics of large visual filed and high visual acuity, which can provide reference for visual information processing technology. Firstly, the differences between eagle-eye and other types of eyes are given, and the current progresses of eagle-eye are introduced. Then, the eagle-eye mechanisms are presented in detail, including the dual fovea, visual acuity, the logarithmic spiral movement of the eagle and eagle-eye visual attention mechanism. Some of the main application directions of biological eagle-eye vision technology are discussed, including cameras, high-resolution devices and automatic focusing. Finally, discussed. interested target extraction, dynamic object tracking, large field the new orientations of biological eagle-eye vision technology are
