Thermal video camera equipped with wide-angle FOV lens has been used to acquire mufti-angular thermalimagery. In order to extract the directional infonmation for individual pixels at different view angles

image merging isneeded to co-register mufti-view angle imagery. This paper describes an automated image merging procedure toaccomplish this task. After analyzing the relationship between TIR image's correlation coefficients

spatial resolution

image texture and image overlap ratios

a mufti-step automatic merging algorithm procedure is described. The method istested using mufti-angular airborne thenmal infrared imagery for an experimental site characterized by agricultural landuse. Results from these tests show that the accuracy is better than one pixel.
