The invention discloses a simplified twenty-four type Tai chi chuan comprehensive training system which comprises a man-machine operation module, a video collection module, a body sensing control module, a data processing module, a motion standard evaluation module, a motion guide suggestion output module, an artificial expert guidance module, a central processor, a rhythm integrating degree evaluation module and an air projection training teaching module. Automatic judgment, evaluation and guidance for Tai chi chuan motions are achieved, teaching videos or guidance videos can be played in a three-dimensional projection mode in the training and learning process, theoretical knowledge is added therein, great convenience is brought to repeated observation and understanding of trainee for each motion, training efficiency is improved, motions are more standard, and meanwhile the workload of teachers is reduced; various training backgrounds can be built, a virtual three-dimensional model can also be built for partner training, and interestingness in the motion training process is improved.
