Camera adjusting device based on parallel mechanism two-degree-of-freedom redundant driving

Abstract

The invention relates to a camera adjusting device based on parallel mechanism two-degree-of-freedom redundant driving. The camera adjusting device is used for solving the problem that the movement precision of a mechanism is declined due to accumulative error of a driving shaft in an existing camera adjusting mechanism. In the camera adjusting device, a movable platform assembly comprises a movable platform and a rotary support, the upper surface of the movable platform is used for mounting a sealed camera, the rotary support is arranged on the lower surface of the movable platform; one end of a middle constraint branched chain is hinged to the rotary support, and the other end of the middle constraint branched chain is fixedly connected with a fixed support; the fixed support is fixedlyconnected with a mounting base plate; a first driving branched chain and a second driving branched chain are the same in structure, one ends of the first driving branched chain and the second drivingbranched chain are hinged to the rotary support, and the other ends of the first driving branched chain and the second driving branched chain and the fixed support form a sliding pair; a third drivingbranched chain and a fourth driving branched chain are the same in structure, one ends of the third driving branched chain and the fourth driving branched chain are hinged to the movable platform, and the other ends of the third driving branched chain and the fourth driving branched chain and the fixed support form a sliding pair; and a first motor assembly, a second motor assembly, a third motorassembly and a fourth motor assembly are the same in structure and are used for driving the sliding pairs to move.

Description

technical field [0001] The invention relates to a camera adjustment mechanism, in particular to a camera adjustment device based on two-degree-of-freedom redundant drive of a parallel mechanism, which can realize two-degree-of-freedom rotation of the camera, facilitate adjustment of the attitude of the camera, and realize clear shooting of a target object. Background technique [0002] When shooting with a camera, often due to its limited field of view, it is necessary to use a camera adjustment mechanism or a camera adjustment platform to adjust the camera attitude. The output motion of each front mechanism is the input of its rear mechanism, so the output motion error of each single-degree-of-freedom mechanism will accumulate to the end of the series mechanism, resulting in a decrease in the motion accuracy of the series mechanism, which in turn affects the high precision. camera pose adjustment.
