Integrated unshielded cradle head driven in offset mode

Abstract

The invention discloses an integrated unshielded cradle head driven in an offset mode. The invention comprises an offset driving mechanism, a fixed main shaft, a rotary main shaft mechanism, a pan-tilt movement structure and a synchronous pulley tensioning mechanism, wherein the offset driving mechanism is arranged on a mounting base, the synchronous pulley tensioning mechanism is connected with the offset driving mechanism through the fixed main shaft and rotary main shaft mechanism, and the cradle head moving structure is connected with the fixed main shaft and rotary main shaft mechanism. The invention is compact and exquisite in structure, and the space required for installation is reduced; meanwhile, due to the fact that the visual occlusion problem does not exist, an extra sensor isnot needed for compensating for the occluded visual field, the hardware cost is greatly saved, and the calculation cost of a software algorithm is greatly reduced; due to the offset driving mode, theinterference problem of the fixed stand column and the movable cradle head is solved, and meanwhile the requirement that a laser radar is fixed and a visual camera needs 360-degree omni-directional movement is met.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicles, in particular to an integrated non-shielded pan-tilt driven by bias. Background technique [0002] Vision cameras and lidar are important sensing parts of unmanned vehicles, which mainly provide information on maps and road conditions for unmanned vehicles. In traditional unmanned vehicles, the vision camera and the lidar are installed on two pillars respectively, which causes the fields of view of the lidar and the vision camera to block each other. Traditional solutions often require multiple cameras or lidars to be installed on both sides of the column, and data fusion is used to solve the problem of occlusion of the field of view. This solution not only greatly increases the hardware cost, but also increases the complexity of the algorithm and reduces the robustness.
