摘　　要：无人机载小型多光谱成像仪是一种小型化的多镜头多光谱成像仪。采用重心法对平行光管出射光在该成像仪各通道所成像点作亚像元定位,得到精度高、分布均匀的大量控制点对,有效的实现了多光谱图像的配准处理。UAV-borne compact multi-spectral imager is a multi-camera imager. Image processing is needed to match the images grabbed by multi channels. Putting the imager in front of the collimator tube; adjusting the source of light into a point, the images containing a spot will be grabbed by each channel of the imager. Applying barycenter method of subpixel location, accurate control point pairs can be calculated and be used to perform image registration effectively.
