摘 要：In order to realize omnidirectional real-time detection and awareness in thermal infrared (IR) region,a kind of biomimetic miniature IR imaging detection system (BMIRIDS) has been successfully *** is classified as a long wave IR(LWIR) system and a mid-wave IR(MWIR) *** former consists of a LWIR fish-eye lens and a LWIR focal plane array (FPA)-biomimetic electronic module,the latter consists of a MWIR fish-eye lens and a MWIR FPA-biomimetic electronic *** can provide complete hemispherical staring field of view,and have the capability to determine target bearings,to remove all stationary scene clutter and only detect moving targets,to sense targets range and their *** capability closely approximates the vision process performed in nature by biological ***,an additional biomimetic module block has been integrated into *** module block imitating the function of human vision produces the logarithmic brightness image,and enhances the target image outline by virtue of the Roberts gradient *** logarithmic transform permits expanding the dynamic range of optical incidence without saturating the electric circuit,and makes the image more suitable for *** and FPGA perform the aforesaid vision functions that are advantageous to detect and track ***,BMIRIDS can perform more powerful real-time signal and image processing on the resulting image data than the ordinary previous systems mainly by the aid of software-only *** BMIRIDS has a 2π-steradian (sr.) staring field-of-view,two of such systems opposed to one another would provide a complete view of space around the sensor *** addition,its low power consumption makes itself meet the manifold platforms’ *** practice has proved that BMIRIDS can truly realize omnidirectional real-time situation awareness and dynamic information *** virtue of biomimetic technology,some limitations of the current photoe
