The invention relates to a wave measurement apparatus for correcting wave characteristic parameters based on multi-parameters, and a wave measurement method thereof. According to the present invention, the sensor with characteristics of mature technology and low cost and other modules are used, and other complicated-design mechanical structures are not required, such that the structure design is simplified, and the cost is low; 1-4 groups of the independent and different multi-parameter sensors are used to perform the synchronous detection, wherein other sensors can be continuously used when one of the sensors fails while the whole detection data collection is not affected, such that the detection reliability and the fault tolerance of the whole equipment are improved; and the derivation is performed by using the traditional formula, the integrating and the secondary integrating are required to be used, and the derivation is non-linear so as to easily produce the error accumulation, while the support vector regression model is used, the target function is fitted by using the non-linear kernel function, the non-linear kernel function is non-linear, the input error is subjected to compatibility, and the calculation is the one calculation, such that the assumptions and the accumulative errors in the derivation are avoided, and the problems of the nonlinearity and the error accumulation of the wave characteristic data derivation are solved.
