Planning airborne photogrammetry and remote-sensing missions with modern platforms and sensors

Abstract

The mission planning in airborne Photogrammetry and Remote Sensing applications, depending on the system of acquisition and by the adopted platform (such as rotary and fixed wing aircrafts, glider, airship, manned or unmanned), is the first and essential step to ensure the success of a survey mission. The purpose of this paper is to provide an overview on mission planning techniques using passive optical sensors. The basic concepts related to the usage of the most common sensor technologies are described, along with the several possible scenarios that may be afforded by using modern airborne sensors. Several examples of flight plans are illustrated and discussed to highlight correct methods, procedures and tools for data acquisition in the case of different types of manned and unmanned airborne missions. In particular, the flight planning with more recent technologies of digital passive optical airborne sensors will be dealt with, including frame cameras and multi-/hyperspectral push-broom sensors. Furthermore, in order to ensure the complete success of an airborne mission, some up-to-date solutions to know in advance the weather conditions (cloud cover, height of the sun, wind, etc.) and the GNSS satellite configuration are illustrated.

3d Modeling of Roman Bridge by the Integration of Terrestrial and Uav Photogrammetric Survey for Structural Analysis Purpose

“…Once established the tolerable error, the next step concerns the determination of the Ground Sample Distance (GSD) using the equation 1. Therefore, taking into account a planning = 1 and the features of the sensors follows that to realize this geometric resolution, the maximum distance between object and sensor is 42 m for the dSLR camera and 8m for the camera supplied with Xiaomi Mi drone, as show in the following (Pepe et al, 2018). In addition, flight lines (FL) inclined at 30° and 45° were designed in a longitudinal direction to the bridge in order to increase the rigidity of the aerial photogrammetric block in the bridge part and, at the same time,…”

Automatic Processing of Many Images for 2D/3D Modelling

“…This data set belongs to the SIFET benchmark described in Piras et al (2017). Since the use of Unmanned Aerial Vehicles (UAVs) allows to predefine the acquisition points, thanks to the GNSS navigation system onboard, the geometry of camera poses can be carefully planned in advance (Pepe et al 2018).…”

Technical Aspects Related to the Application of SFM Photogrammetry in High Mountain

“…Readers are addressed to the specific literature, in particular to O'Connor et al (2017) and Pepe et al (2018).…”

“…The immediate step after the use of satellite data is given by standard airborne sensors, mainly encompassing aerial photogrammetry (Pepe et al, 2018) and airborne LiDAR (Shan & Toth, 2009). While increased performances maybe achieved, these consolidated techniques involve the organization of a tailored flight mission in the case new data acquisition is necessary.…”
