Abstract: The invention is applicable to the field of wireless indoor positioning, and provides a positioning method and apparatus based on an indoor virtual landmark. The method comprises the steps of acquiring acceleration data of a user, moving direction data and a wireless signal receiving strength RSS value of a position by using a mobile terminal, and taking the wireless signal receiving strength RSS value as an RSS fingerprint of the position; identifying behaviors of the user entering or leaving an indoor virtual landmark according to the acquired acceleration data of the user and the RSS fingerprint; taking the position of the indoor virtual landmark as a reference point, acquiring the moving distance and moving direction, and establishing and updating a positioning fingerprint database; and according to the user fingerprint acquired in real time and a fingerprint in the positioning fingerprint database, positioning the user in real time, generating an indoor positioning result, and modifying the indoor positioning result according to the identification of the behaviors of the user entering or leaving the indoor virtual landmark. The invention can improve the accuracy of user positioning, and can also perform indoor positioning directly by using the mobile terminal while saving the equipment cost.
