Abstract

The invention discloses a method for solving the singular problem of a three-axis stabilization system with each axis thereof close to a vertical plane. The method is used for regulating and controlling the stability of the three axes. According to the invention, based on the method, a table body is prevented from shaking or turning over when each axis of the three-axis stabilization system is close to the vertical plane. As a result, objects borne by the table body are prevented from being damaged. In addition, under the singular working state, the orientation and the lateral rolling of the table body can still be kept stable. As a result, the stabilizing effect of the table body applied in many application occasions can still be acceptable.

Description

technical field [0001] The invention belongs to the field of photographing, and in particular relates to a method for solving the singular problem that each axis of a three-axis stabilization system is close to a vertical plane. Background technique [0002] The three-axis stabilization system generally consists of a table body, an inner ring, an outer ring, and a base. The table body and the inner ring are hinged through the inner ring shaft; the inner ring and the outer ring are hinged through the inner shaft; The space is hinged by the outer shaft, and the attitude sensor combination for measuring the relative earth inclination and orientation of the platform is installed on the platform body. A motor is installed on the platform axis, inner axis and outer axis respectively, and the platform axis, inner axis and outer axis are respectively installed. Install one shaft angle sensor each. [0003] When the axis of the three-axis stabilization system coincides with the oute...
