The monitoring system comprises a first time synchronization mechanism and a first supersonic wave mechanism which are arranged on a first device, a second time synchronization mechanism and at least three supersonic wave mechanisms which are arranged on a second device, a distance calculation module and a real-time position determination module, wherein the at least three supersonic wave mechanisms are not center-colinear; distance calculation module is used for calculating the distance between each second supersonic wave mechanism and the first supersonic wave mechanism, time T obtained by each timer is multiplied by the propagation speed V of supersonic waves, and the distance between a supersonic wave receiver and a supersonic wave generator is obtained; the real-time position determination module comprises a first position determination unit, the first position determination unit is used for determining the position relation between the first device and the second device according to the distances between the second supersonic wave mechanisms and the first supersonic wave mechanism and the positions of the three second supersonic wave mechanisms. According to the invention, the changes of relative movement and displacement of two objects in the space can be precisely obtained.

Description

Technical field

[0001] The invention belongs to the field of electronic information technology, and relates to a displacement change monitoring system, in particular to a spatial relative displacement change monitoring system. Background technique

[0002] With the rapid development of science and technology, the types of electronic products are becoming more abundant. The control method of electronic products is usually controlled by remote control.

[0003] In recent years, virtual reality and motion sensing technologies have appeared in some game equipment; existing control methods usually use machine vision for posture and displacement detection; such methods are widely used in virtual reality, but there are many disadvantages, such as The machine vision solution using 3D camera and structured light has high hardware cost and high power consumption. It has requirements for the light of the use occasion, the size of the venue, whether there is obstruction, and the detection dis...
