Parachuting control motion quantitative evaluation method and system

Abstract

The present invention discloses a parachuting control motion quantitative evaluation method and system. The method comprises the steps of: establishing a virtual human body model; obtaining attitude data of a head, trunks and limbs of a parachutist in the whole parachuting process; mapping the attitude data to the virtual human body model, and determining motions of a virtual human body in the virtual human body model; and performing comparison and matching of the motions of the virtual human body model and standard motions in an expert database, and giving a quantitative evaluation result according to a matching degree. The method and the system provided by the invention can achieve objective and effective quantitative evaluation of the normativity of the parachuting motions of trainers.

Description

technical field [0001] The invention relates to the field of skydiving training evaluation, in particular to a method and system for quantitative evaluation of skydiving manipulation actions. Background technique [0002] Skydiving is a sport with high technical requirements and a high risk factor, which has high physical and psychological requirements for skydivers. A series of operation actions of a parachute from the process of leaving the plane to landing involves personal safety and the accuracy of the landing site. Therefore, parachute manipulation is a basic skill that a parachute must master. , and pass the assessment before you can participate in the actual skydiving. [0003] At present, the evaluation method of parachuteman's maneuvering action in actual training is mainly that the coach visually observes the parachutist's action on the spot, and conducts qualitative scoring evaluation based on his own experience. This method is highly subjective and has no clear...

Problems solved by technology

[0003] At present, the evaluation method of parachuteman's maneuvering action in actual training is mainly that the coach visually observes the parachutist's action on the spot, and conducts qualitative scoring evaluation based on his own experience. This method is highly subjective and has no clear scoring standard , the result is greatly affected by human factors, and the trainer can only give a qualitative description of the parachutist's movements by naked eye observation and memory, lacking quantitative analysis and mastery of all the details of the movements

In addition, because it cannot be reproduced, it is difficult to guide and correct the action afterwards
