A Self-stabilized Aerial Camera Platform Based on Parallel Mechanism

Abstract

The invention relates to a connecting device adapting to aerial photography, in particular to a self-stabilization aerial photography pan-tilt device based on a parallel-connection mechanism. The self-stabilization aerial photography pan-tilt device comprises a suspension bracket, a parallel-connection self-stabilization device, a rotation device, a swing device, an overturn device, a movement device and a photographing device. The suspension bracket is located over the parallel-connection self-stabilization device and connected with the parallel-connection self-stabilization device through a fixed seat. The rotation device is installed between the parallel-connection self-stabilization device and the swing device. The overturn device is located right in front of the swing device. The movement device is connected with the overturn device. The photographing device is fixed to the movement device. According to the self-stabilization aerial photography pan-tilt device, the jittering problem in the aerial photography process is effectively solved through the parallel-connection self-stabilization device; omnibearing photography can be realized through the pan-tilt device with four degrees of freedom, namely one degree-of-freedom horizontal movement and three degree-of-freedom rotation, so that the photography efficiency and quality are improved. The self-stabilization aerial photography pan-tilt device further has the advantages of being compact in structure, convenient and fast to disassemble and assemble, high in safety performance and the like, and is suitable for aerial photography by various types of aircrafts.

Description

Technical field [0001] The invention relates to a connecting device suitable for aerial photography, in particular to a self-stabilizing aerial photography platform based on a parallel mechanism. Background technique [0002] The pan-tilt is a commonly used support device for installing and fixing cameras in surveillance systems. It does not directly receive images, but the pan-tilt controls the direction of rotation of the camera or other equipment. Aerial photography gimbal is a category of gimbal. It is mainly used for practical aerial photography such as construction planning, engineering survey, disaster survey, emergency rescue and disaster relief, such as shooting during the Wenchuan earthquake and Ya'an earthquake, and before road construction in high mountains and mountains. Environmental survey, etc. [0003] In the actual application process, due to the continuous change of the drone's own attitude during the flight, the entire fuselage is brought to a certain degree of...

Problems solved by technology

At present, the stability enhancement measures for aerial photography gimbals are generally realized through electronic equipment detection systems, but the electronic detection systems all have a certain lag, and cannot adjust the aerial photography gimbals in time according to the changes in the attitude of the UAV during flight. Compensation for the attitude of the aerial photography gimbal, only a few of the existing Chinese patents propose to solve the problem of stabilization of the aerial photography gimbal through the mechanical structure

[0004] The new type of aerial photography cloud platform published by the Chinese patent No. ZL201220429927.3 proposes a technical solution that combines the camera frame pillar and one of the legs of the tripod into one. Although the weight of the platform is reduced, it does not solve the problem of cloud The problem of increasing the stability of the platform; the application number is the Chinese patent of ZL201210072223.X, which discloses the aerial photography platform of the aircraft, which solves the stability problem of the aerial photography platform in the three directions of XYZ by adopting the X-axis knot, the Y-axis structure and the Z-axis structure , but the adjustment range and angle are limited; the Chinese patent application number ZL200910258080.X discloses a three-degree-of-freedom inertial stabilized aerial photography platform. To ensure the stability of the aerial photography platform, but because the high-speed rotor is prone to mass imbalance, is easily affected by acceleration, and needs a period of warm-up time to stabilize the speed, it is not convenient in practical applications.
