Image alignment is an essential step for 3D reconstruction of organs from serial sections. The conventional means are proved to be either unsuitable or inefficient for microscopies of pulmonary alveolus. A technical description of the alignment problem for micro-section of soft tissues is presented. An efficient automatic alignment algorithm for 3D reconstruction of pulmonary alveolus sections, based on pyramid structure, is proposed. The resultant images of 3D reconstruction demonstrate that our algorithm is promising.
