    摘要: An algorithm of collecting and constructing training location data is provided as it is applied to a test space of a plurality of beacons and training locations. The signal patterns of beacons adjacent to each training location are detected. The signal pattern is converted into a signal vector and each signal vector is integrated for calculating a feature vector of each training location. The coordinate and the feature vector of each training location, after being recorded, are introduced into a numerical data fitting model for constructing the signal pattern function of each beacon. For positioning, the current signal patterns of the beacons adjacent to the user location are detected and converted to a discriminant function. Thereafter, the minimum of the discriminant function is computed so as to find the position of the user location.

    摘要: A method for positioning a mobile device includes following steps. Based on a prior location point of the mobile device, many sample particles are generated according to a prior probability distribution associated with the prior location point. A current moving track or a current behavior mode of the mobile device is obtained, and the sample particles are moved according to at least one of the current moving track and the current behavior mode. A current supposed status is obtained based on a radio frequency signal received by the mobile device. A current probability distribution of the sample particles corresponding to the radio frequency signal or the current supposed status is generated to obtain corresponding weights of the moved sample particles. A current location point of the mobile device is obtained according to the weights and distribution of the sample particles.

    摘要: A positioning method and a positioning system based on light intensity are provided. The positioning system comprises a lighting system, a sense feedback device and a positioning module. The lighting system comprises at least three point light sources and sequentially adjusts luminance of these point light sources to light up a target. The sense feedback device is disposed on the target and used to collect light intensity information of the light projected on the target by the lighting system. The positioning module calculates a distance between the target and each of the point light sources based on the light intensity information and calculates a positioning location of the target based on the locations of the point light sources and the distances between the target and the point light sources.
