Miniature and compact rope rotation angle measuring device

Abstract

The invention provides a miniature and compact rope rotation angle measuring device which is used for measuring a pitch angle and a rotation angle of a straightened rope at a fixed end. The device comprises a base arranged at the fixed end of the rope, a U-shaped cover, a first angle measuring device and a second angle measuring device, wherein the rope enters from the side face of the base, and a first rotating arm and a second rotating arm which surround and abut against the rope from the two sides are arranged on the base; two ends of the U-shaped cover are respectively hinged with the first rotating arm and the second rotating arm; the rope extends out of the middle of the U-shaped cover and is connected with a target end; the first angle measuring device is used for measuring a pitch angle formed by the rotation angle of a surrounding body formed by the first rotating arm and the second rotating arm along with the rope; and the second angle measuring device is used for measuring a rotation angle formed by rotating the U-shaped cover around a hinged shaft. The pitch angle of the rope is sensed through rotation of the two rotating arms, the rotation angle is sensed through the U-shaped cover hinged to the two rotating arms, the product structure is simple and compact, and the measurement precision is high.

Description

technical field [0001] The invention relates to the field of miniature and compact rope angle measuring devices. Background technique [0002] Virtual reality technology (Virtual Reality VR) mainly includes aspects such as simulated environment, perception, natural skills and sensing equipment. The simulated environment is a real-time dynamic three-dimensional realistic image generated by a computer. Perception means that ideal VR should have the perception that all human beings have. In addition to the visual perception generated by computer graphics technology, there are also perceptions such as hearing, touch, force, movement, and even smell and taste, also known as multi-sense. Natural skills refer to people's head rotation, eyes, gestures, or other human behaviors. The computer processes the data that is suitable for the participants' movements, and responds to the user's input in real time, and feeds back to the user's facial features. [0003] In the process of pe...

Problems solved by technology

Therefore, the applicant decided to adopt a kind of rope tied to some parts of athletes or game players, such as wrists, ankles, waist, shanks, the forehead of the head, etc. The ropes on the positions where markers are set, the length of the rope is the above Said distance, the angle between the rope and the ground is the pitch angle, and the angle between the rope and the set direction is the rotation angle, but there is no rotation angle measuring device for measuring the pitch angle and rotation angle of such a rope.
