Automatic route selection and exposure device for aerial survey camera

Abstract

The invention discloses an automatic route selection and exposure device for an aerial survey camera. The device comprises a data collection module which is used for obtaining real-time navigation data and route planning data, a data preprocessing module which is used for performing Gaussian projection preprocessing on the real-time navigation data and the route planning data, a flight mission maintenance module which is used for constructing a flight mission matrix according to the route planning data subjected to Gaussian projection preprocessing, a route selection module which is used for carrying out route judgment according to the real-time navigation data subjected to Gaussian projection preprocessing and the flight mission matrix, a fixed-point exposure module which is used for carrying out exposure judgment after Gaussian projection preprocessing, and a hardware control module which is used for sending a corresponding instruction according to the route judgment result and the exposure judgment result. The flight state of the aerial survey camera can be automatically judged, exposure of the camera and opening and closing of the stable platform are automatically controlled, full-automatic operation of flight missions can be achieved, the exposure point location precision is high, and the variable baseline aerial photography requirement can be met.

Description

technical field [0001] The invention belongs to the technical field of aerial photogrammetry and remote sensing, in particular to an automatic route selection and exposure device for an aerial survey camera. Background technique [0002] Aerial photogrammetry has the advantages of strong autonomy, high precision, flexibility and convenience, etc. It is an effective means to quickly obtain high-precision terrain data. With the rapid progress of technology, advanced aerial photogrammetry systems are generally equipped with stable platforms, which further improves aerial photography The geometric quality of the photo. [0003] Traditional aerial survey cameras use timing or manual exposure methods. These exposure methods will cause differences in exposure intervals, unstable overlapping rates of aerial photos or even missed shots due to factors such as uneven flight speeds and airflow changes, and cannot adapt to variable baseline aviation in hilly areas. photography needs.
