 The high-precision, real-time and high-resolution photos, Orthophoto and video obtained by UAV aerial photography provide accurate basic geographic data support for 3D seismic acquisition in complex surface. Taking advantage of UAV aerial photography, we can accurately identify the obstacles on the ground, perform efficient indoor design and construction within a safe distance to improve the acquisition efficiency. Combining the characteristics of 3D high-precision seismic survey acquisition, the application of UAV aerial photography in exploration are summarized, including the overall planning of sub-areas, efficient design, accurate reconnaissance, optimized route, fine implementation and HSSE management, etc. Taking an actual project for example, using high-definition image as the base map, we overlay and analyze various kinds of geographic information data to achieve the key deployment for key areas, explicate target layers and guide the field arrangement and route planning of vibro-seis. With the UAV aided field collection process, vectorized and evidence-based management and traceable process operation, field construction time frame will be greatly reduced to improve efficiency and construction safety.
