aerial-mapper

Overview

• Load camera poses from different formats (such as PIX4D, COLMAP)
• Generates a dense point cloud from raw images, camera poses and camera intrinsics
• Generates Digital Surface Models (DSMs) from raw point clouds and exports e.g. to GeoTiff format
• Different methods to generate (ortho-)mosaics from raw images, camera poses and camera intrinsics

Package Overview

• aerial_mapper: Meta package
• aerial_mapper_demos: Sample executables.
• aerial_mapper_dense_pcl: Dense point cloud generation using planar rectification.
• aerial_mapper_dsm: Digitial Surface Map/Model generation.
• aerial_mapper_google_maps_api: Wrapper package for Google Maps API.
• aerial_mapper_grid_map: Wrapper package for grid_map.
• aerial_mapper_io: Input/Output handler that reads/writes poses, intrinsics, point clouds, GeoTiffs etc.
• aerial_mapper_ortho: Different methods for (ortho-)mosaic generation.
• aerial_mapper_thirdparty: Package containing thirdparty code.
• aerial_mapper_utils: Package for common utility functions.
