METHODS AND APPARATUS FOR PROCESSING IMAGE STREAMS

摘要

Apparatuses and related methods for obtaining 3-dimensional spatial data associated with civil infrastructure. The method includes obtaining a stereo videogrammetric video, via a first and second video camera. The video includes a first plurality of video frames of the infrastructure. The method further includes calibrating the first and second video camera. The method also includes detecting a second plurality of features of the infrastructure selected from the group consisting of lines, points, and planes of the infrastructure in a third plurality of video frames from the first plurality of video frames of the infrastructure. The method further includes matching the second plurality of detected features of the infrastructure in the third plurality of video frames.
