The invention discloses a virtual auditory replay method and system. The method includes the following steps that according to the preset image processing algorithm, N auricle parameters different in type are extracted from auricle images, based on the preset parameter interrelated algorithm and standard auricle parameters, contained in a database, of several tested persons, weighting coefficients corresponding to the N auricle parameters different in type respectively are calculated, according to N auricle parameters of a target object and weighting coefficients corresponding to the N auricle parameters, the similarity matching degree of the N auricle parameters of the target object and the standard auricle parameters of the tested persons is calculated, HRTF data, high in similarity matching degree, of the tested person serves as the HRTF data of the target object, and virtual auditory replay is conducted according to the HRTF data of the target object. The auricle parameters obtained by means of the method are small in error and high in accuracy, the virtual auditory replay effect is improved, and by using the weight coefficients, more accurate matching can be achieved.
