The invention provides a focusing method and system based on self-learning, a terminal and a medium. The method comprises the following steps: acquiring object distance value data of a current shot subject; searching whether a corresponding credible value exists in the updated focusing curve or not according to the object distance value data of the current shot main body; and if the credible value exists, taking the searched credible value as a lens motor control value to drive the lens motor to move to a specified position for focusing. According to the invention, through the self-learning algorithm, the calibration can be learned to obtain the updated focusing curve, so that in the subsequent focusing process, the accurate position can be focused in one step only through the object distance value obtained by the TOF, the CAF fine focusing does not need to be repeatedly carried out, the influence of a picture blurring stage generated by the CAF focusing is eliminated, the system computing power required by t
