Research on low-cost technology of hand capture applicable to GCS human factors engineering assessment

Abstract

In order to achieve unmanned aerial vehicle operation control “human — machine — environment” coherence as a typical example of the application of loop control, the design and development of the modern unmanned aerial vehicle ground control station (GCS) is widely use human engineering. However, due to the extreme lack of human data in the actual environment, GCS human reliability analysis and evaluation work is seriously limited. Thus, with the CGS human engineering evaluation background, this paper relies on low-cost hardware equipment Leap Motion to carry out human data capture technology. First of all, the feasibility of GCS manpower data acquisition on Leap Motion was proofed by analyzing the space adaptability, capture speed accuracy adaptability and secondary development ability etc. Then those key technologies including action capturing, action modeling and information processing were studied and specific work processes and application opportunities were discussed. From the final results, gestures and motions of virtual hands were same as real ones. The building processing speed was far from minimum demand of 15 frames per second. The accuracy and real-time performance of analysis demonstrated the movements accurately capture and data processing ability on the whole, which satisfied real time and accuracy requirements for the manpower data capturing.
