无拼接盲区的图像拼接光学布局及系统设计

Optical Layout and System Design of Image Mosaic Without Splice Blind Area

现有的图像拼接系统具有拼接盲区的缺陷,对于监控系统会造成观察盲区,形成信息缺失,对监控安全造成威胁。本文为了消除图像拼接系统的拼接盲区,提出了一种新的无拼接盲区的图像拼接布局型式。首先,对具有拼接盲区的图像拼接布局型式与无拼接盲区的图像拼接布局型式的优缺点进行分析;其次,以3个非制冷长波红外摄像机图像拼接系统为例,对非制冷长波红外摄像机镜头进行设计分析;最后,为了得到比较好的拼接图像,对待拼接的红外摄像机的畸变提出相应的处理措施。

Existing image mosaic systems exhibit the defect of blind area,which causes blind spots in the monitoring system,leads to information loss,and poses a threat to monitoring security.In order to eliminate the mosaic area resulting from the processing by the image mosaic system,a new mosaic pattern without splicing the blind area is proposed in this work.First,the advantages and disadvantages of the image stitching layout patterns with and without stitching blind areas are analyzed.Second,using the image mosaic of the images obtained from three uncooled longwave infrared cameras as an example,the design and analysis of the uncooled longwave infrared camera lens is carried out.Finally,in order to obtain a better stitched image,a corresponding treatment measure is provided for the distortion of infrared cameras.
