Method and device for counting number of turns

Abstract

The invention discloses a method and a device for counting the number of turns. The method comprises the following steps that: when a command of counting the number of turns is received, the direction of a moving object starts to be acquired, wherein the direction acquired first is the initial direction of the moving object; and when the include angle between the acquired direction and the initial direction is greater than a first preset value but smaller than a second preset value, the number of turns of the moving object is plus 1. The method and the device in the embodiment of the invention judge that whether the moving object moves a circle around according to the angle difference between the direction of the moving object during the moving process and the initial direction, can finish the counting of the number of turns without a GPS (Global Positioning System), is wider in application range, can be used indoors or used in a scene with shorter distance.

Description

technical field [0001] The present invention relates to the field of data processing, and more specifically, to a method and device for counting laps. Background technique [0002] In competitive sports such as running, athletes need to run many laps on the track. For example, in a 10,000-meter long-distance race, they need to run 25 laps on a standard 400-meter stadium track. Generally, staff are required to count the number of laps actually completed by the athletes. , such statistical operation is cumbersome, easy to press by mistake, time error is large, and consumes a lot of manpower and material resources. [0003] With the popularization of GPS (Global Positioning System, Global Positioning System) technology, some sports competitions have begun to use GPS to count the number of laps completed by athletes, saving some manpower. [0004] However, because GPS positioning cannot search for satellite signals indoors, the circle counting method utilizing GPS cannot be app...

AI Technical Summary

Problems solved by technology

[0004] However, because GPS positioning cannot search for satellite signals indoors, the lap counting method using GPS cannot be applied to indoor events (such as field running, field roller skating, field racing, field cycling, field horse racing)

In addition, because the GPS recognition accuracy requires the radius of the runway to reach ten meters, otherwise it will not be correctly recognized, so the lap counting method using GPS cannot be applied to some short-distance events and games, such as round-trip races (climbing, parent-child games, Variety show games), etc., have relatively large limitations
