The invention discloses a method for measuring the tensile strength of a rock sample based on a synchronization method. The method comprises the following steps: (1) preparing the rock sample and putting the prepared rock sample on a servo test machine; (2) enabling the rock sample to be clearly presented in a lens; (3) starting a high-definition video camera for shooting and then quickly starting testing; (4) finding a moment corresponding to a mutation point of vertical deformation of the rock sample; (5) importing a video shot by the high-definition video camera into a computer; (6) playing the video and grabbing 12 pictures in total; (7) inserting the pictures into AutoCAD software; (8) realizing data image synchronization; (9) calculating the tensile strength of the rock sample. The method for measuring the tensile strength of the rock sample based on the synchronization method can enable data at any moment to be synchronized with video shooting, and test data is optimized and screened to obtain a result better conforming to real tensile strength of the rock sample.
