Abstract

The invention discloses a sit-up counting method based on a long short-term memory (LSTM) algorithm. The method comprises the following steps: acquiring a real-time accelerometer data stream of sit-up of a testee by using an accelerometer; storing the accelerometer data stream in a period of time into a data file, and filtering the stored data file by using an FIR filter to obtain smooth data; the smooth data are segmented through a crest value detection method, crest indexes are recorded, and data between every two crests are recorded as possible sit-up data; and judging whether the obtained data possibly being one sit-up is a standard and complete sit-up or not through a long short-term memory (LSTM) algorithm, and adding 1 to a counter after the complete and standard sit-up is completed. According to the sit-up counting method and system, automatic test counting of sit-ups can be achieved, human intervention is not needed in the process, the working efficiency is improved, and meanwhile the accuracy and preciseness of sit-up counting are improved.

Description

technical field [0001] The invention belongs to the technical field of computers, in particular to a method for counting sit-ups based on a long-short-term memory LSTM algorithm. Background technique [0002] As a common exercise method, sit-ups are very effective for the exercise of multiple muscle groups and the enhancement of core strength. Therefore, sit-ups play an important role in domestic student physical fitness tests and military physical fitness evaluations. status. Accurate and precise counting methods are essential for promoting a comprehensive national sport such as sit-ups. [0003] The main methods of counting sit-ups currently in use are: [0004] (1) The statistician judges and counts manually. Statisticians observe the subjects doing sit-ups, and then count them manually. Using this counting method requires more human resources to cooperate. At the same time, it is impossible to confirm whether the movements are standardized, and it is also prone to fra...
