Aerial oblique camera is equipped with five high-pixel lenses, which can break through the limitations of single-angle images on traditional mapping camera. By mounting multiple camera sensors on the same flying platform, it will acquiring real images with spatial information from multiple different angles, vertical and tilt. To present more details of the texture feature.The 3D data of oblique camera can realistically reflect the appearance, position, height and other attributes of ground features. Enhance the high immersion and to make up for the shortcomings of low artificial simulation of traditional modeling. It can bring revolutionary efficiency improvements to the mapping filed by using UAV and automatic modeling systems.
