Problems solved by technology

[0003] There are a small number of swimming sports that use sensor technology in technical analysis, but video and sensor monitoring methods are often used separately, which will result in: using video analysis technology alone, it is impossible to accurately understand the athlete's strength in each technical action link; Using strength testing equipment alone to collect strength data cannot accurately judge the rationality of the athlete's strength state in the entire technical movement
However, the special underwater environment brings many difficulties to synchronous transmission

Abstract

The invention discloses a technical analysis system and method for swimming exercise. The system comprises a data acquisition module based on a wireless sensor network, a video acquisition device, a synchronizer and a control host, the data acquisition module based on the wireless sensor network comprises a wearable device for wearing of a user, a synchronization node and a wireless gateway, a sensor node for acquiring data is arranged in the wearable device, the control host is connected with the sensor node through the wireless gateway, video signals of the video acquisition device are connected to the control host in a wired manner, the synchronization node receives signals of the control host and outputs synchronous pulse signals of the wireless sensor network to the synchronizer, andthe synchronizer controls the video acquisition device and the sensor node to synchronously acquire the signals and videos, so that the whole system is synchronized. In a real-time training state, exercise videos are accurately acquired, and physiological parameters and exercise parameters of swimmers and parameters of exercise environments are synchronously acquired and measured.

Description

technical field [0001] The invention belongs to the technical field of motion analysis and research, in particular to a technical analysis system and method for swimming. Background technique [0002] In the existing technical analysis of swimming sports, the analysis of the user's posture is mainly through the means of video, but there is a lack of quantified specific parameters. The analysis of swimming videos has high requirements for the angle of video shooting and the quality of videos, which usually leads to errors. [0003] There are a small number of swimming sports that use sensor technology in technical analysis, but video and sensor monitoring methods are often used separately, which will result in: using video analysis technology alone, it is impossible to accurately understand the athlete's strength in each technical action link; Using strength testing equipment alone to collect strength data cannot accurately judge the rationality of the athlete's strength sta...
