The invention relates to a transformer substation simulation training technology and specifically relates to a power transformation simulation human body motion capturing method based on optical and inertial body feeling data fusion. The invention solves the problems that an existing motion capturing system is complex in data processing algorithm, large in calculation amount, unable to work when marking points are confused or shielded and unable to carry out human body positioning and accumulated error control. The power transformation simulation human body motion capturing method based on optical and inertial body feeling data fusion comprises the following steps of: 1) obtaining a group of human body motion data respectively through a Kinect body feeling device and an inertial sensor; 2) utilizing a Kalman filtering algorithm carry out data fusion on the two groups of human body motion data, and obtaining a high quality human body skeleton model; and 3) extracting human body motion characteristic identification actions, and then driving virtual humans in a power transformation simulation virtual environment to complete the corresponding actions. The power transformation simulation human body motion capturing method based on optical and inertial body feeling data fusion is applicable to transformer substation simulation training.
Description
technical field [0001] The invention relates to substation simulation training technology, in particular to a substation simulation human motion capture method based on fusion of optical and inertial somatosensory data. Background technique [0002] The substation is an important part of the power system. With the improvement of its automation, higher requirements are put forward for the operation and maintenance personnel. Due to the particularity of the power system, training cannot be conducted directly by operating the power equipment in actual operation, so it is necessary to carry out simulation training. Transformer Training Simulator is an effective means of substation training, and it is an improvement and supplement to theoretical study and on-site practical study. The current substation simulation training software mainly uses conventional multimedia methods such as wiring diagrams, equipment photos and on-site video as the means of expression, and its sense of r...
