The invention discloses a spatial cognitive ability training method and system based on VR equipment, and the training method comprises the steps: A1, receiving a scene triggering instruction, and displaying a virtual reality scene; A2, receiving a training level instruction, and determining corresponding path information; A3, receiving a training starting instruction, displaying a current user role in the virtual reality scene, and automatically walking according to the path information; A4, when the walking direction needs to be selected at the intersection of the path information, sending an operation prompt tone to the user; A5, receiving direction information triggered by a user, judging whether the direction information is correct or not, and if not, sending out a selection error prompt tone; and A6, receiving direction information triggered by the to-be-trained user again, judging whether the direction information is correct or not until the triggered direction information is correct, and enabling a current user role displayed in the virtual reality scene to automatically walk according to the path information until a destination is reached. According to the invention, the user can train the spatial cognitive ability in the virtual reality scene.
