A single-axis stable pan-tilt with roll angle motion isolation and its control method

Abstract

A roll angular motion-isolated single-axis stable pan-tilt, comprising a pan-tilt handle (1), a motor (2), a photographing device fixture (6), and a circuit bin (3). A circuit board (4) and a power module (5) are provided in the circuit bin (3); a master control module, a gyroscope, and an accelerometer are provided on the circuit board (4); the motor (2) comprises a motor rotor and a motor stator; the pan-tilt handle (1) is fixedly connected to the motor rotor; the motor stator is fixedly connected to the circuit bin (3); the photographing device fixture (6) is fixedly connected to the circuit bin (3); the photographing device fixture (6) is used for clamping a photographing device. The single-axis stable pan-tilt inhibits the influence of angular motion of a carrier in an axial direction of a roll of a photographing device on the photographing device, thereby effectively improving the definition and stability of a photographed image. In addition, the single-axis stable pan-tilt is scientific and reasonable in design, safe and effective, low in costs, small and portable, free of noise, and energy-saving, and is widely applicable to various photographing scenes, and particularly applicable to handheld photographing scenes such as a mobile phone and a motion camera.

Description

technical field [0001] The invention belongs to camera carrier equipment, and in particular relates to a single-axis stable pan-tilt with roll angle motion isolation. Background technique [0002] The stable gimbal is a bearing device that can provide a stable direction for the camera in a moving state, and is widely used in drone-mounted shooting systems, vehicle-mounted shooting systems and handheld shooting systems. During the motion shooting process, the angular movement of the carrier (UAV, vehicle or photographer) is isolated, so that all (three) or part (one or two) angles of the camera to the ground are free to change or change according to dynamic laws , so as to improve the clarity and stability of the shooting picture. Stabilized gimbals are divided into three-axis stabilized gimbals, dual-axis stabilized gimbals, and single-axis stabilized gimbals according to the number of degrees of freedom that can be isolated. [0003] The existing single-axis stabilized gi...
