A system and method for real-time display of position and posture of large-scale construction machinery

Abstract

The invention discloses a pose real-time display system and method of large engineering machinery. The pose real-time display system comprises a multi-sensor information acquisition system, a data processing center and a pose display system body. Linear acceleration information and angular acceleration information of moving parts are acquired by a plurality of pose measuring units in real time andpreliminarily fused to obtain attitude angle information of the moving parts, fused attitude information is transmitted to the data processing center, attitude information of different portions is further fused by the data processing center, spatial coordinate relations of different parts of the engineering machinery are reconstructed according to a 3D (three-dimensional) model file of the engineering machinery and transmitted to the pose display system body, and 3D reconstructing and displaying of pose information of the engineering machinery is further performed, so that real-time pose display of the large engineering machinery is achieved. According to the system, the pose information of the large engineering machinery is monitored and displayed in real time by the aid of a measuring device which is low in cost and easy to disassemble, requirements in severe environments can be met, and safety and the human-computer interaction performance of the large engineering machinery are greatly improved.

Description

technical field [0001] The invention relates to the fields of sensor technology, mechanical dynamics, engineering vehicles, virtual reality, and human-computer interaction, in particular to a system and method for real-time display of position and posture of large-scale engineering machinery. Background technique [0002] Large-scale construction machinery is widely used in construction sites, emergency rescue and disaster relief and other places. It has the characteristics of variable structure, variable load, random change of center of mass position, and driving on non-structural terrain, so it is prone to accidents. The real-time display of the position and orientation of large-scale construction machinery has important research significance and practical application significance for enhancing its human-vehicle interaction and remote control performance. [0003] At present, posture capture and reconstruction technology have been widely used in important research fields ...
