Abstract

Abstract:

To provide a basis for the application research of Unmanned Aerial Vehicle-based Remote Sensing (UAVRS) in forest resources monitoring, we summarized the technical flow of UAVRS in forest resources monitoring, concluded the sensor types commonly used, and analyzed the application and performance of UAVRS in forest disease and pest monitoring, stand tree height measurement, forest canopy structure and attribute determination, tree species composition recognition, and forest biomass measuring. The conclusions show that using UAVRS equipped with various types of sensors to collect forest information will be an important research direction in forest resources monitoring in the future; and that the information extraction of the forest structure parameters in a manner of digitization, informationization and automation will be the development trend of UAVRS in forest resources monitoring. In addition, the UAVRS equipped with diversified sensors and the miniaturization and commercialization of sensors will further promote the precise monitoring of forest resources.
