Resumo

Remotely Piloted Aircrafts (RPAs) are commonly used as a platform for collecting images which can be processed with Structure from Motion-Multi View Stereo (SfM-MVS) to generate 3D mod-els. However, mobile applications for mapping planning are not designed for image acquisition of vertical surfaces, such as quarry walls or large cliffs, leaving the user to a manual flight operation, which does not ensure optimal overlap between images. Here we describe a workflow, based on the Litchi App, for automated RPA missions designed to acquire images of vertical surfaces or structures.center dot An easy-to-follow 8 steps method to survey vertical surfaces using a Remotely Piloted Aircraft.center dot It can be applied to outcrops, quarry walls, high cliffs and virtually any other type of vertical surface.center dot The workflow is flexible and can be adapted to a variety of target configurations and user -defined parameters.
