Method and apparatus for indoor positioning |
| abstract |
A positioning unit mountable on a moving object includes at least one light source measuring unit and a processor. The light source measuring units have high directional sensitivity along a first axis and low directional sensitivity along a second axis orthogonal to the first axis to capture relative angular information of the moving object with respect to a plurality of simultaneously active stationary light sources located at multiple locations in a space. The processor determines positioning information of the moving object at least from the output of the at least one light source measuring unit. Each light source measuring unit includes an optical arrangement and a linearly configured imaging sensor to receive light from the stationary light sources through the optical arrangement. |
