Introduction
LiMapper is an aerial photogrammetry software which can reconstruct 3D geometry structure from overlapping images and subsequently generate a series of standard products of surveying and mapping. The key advantages of the software include automated process, high efficiency, robust performance, and professional accuracy. All this stems from the state-of-the-art photogrammetry and computer vision algorithms implemented in LiMapper, which are accelerated by fully exploiting hardware resources such as multi-core CPU and high-performance GPU. Based on data-processing experience, the algorithms are further optimized to handle not only traditional aerial images of large frames, but also UAV-images with unstable orientations and unknown lens distortions. Considering user friendliness the well-designed software interface is kept simple and easy to use for both novice and expert users.
LiMapper has the scalability to process more than 10000 photos in a project. Supported source data types are nadir, oblique, and multispectral photos. The core functions/modules of the software include feature point extraction/matching, bundle block adjustment, camera self-calibration, dense reconstruction, DEM/DSM generation, smart ortho-mosaicking, true orthophoto generation, stitching line editing, data visualization and analysis.
