This paper presents a method to build ne resolution digital terrain maps, on the basis of a set of low altitude aerial stereovision images. Stereovision images are the only data available: to build a global map, we i n troduce an algorithm that uses interest point m a t c hes between successive images to estimate their relative position. Experimental results are presented and discussed, they show h o w one can build thousands square meters ne resolution maps, integrating hundreds of stereovision images acquired by a tethered blimp.
Early research of Lacroix REF presents a method to build fine resolution digital terrain maps on the basis of a set of low altitude aerial stereo vision images.
