An apparatus of positioning with curved light surface includes a transmitter for transmitting optical signals and a receiver for receiving optical signals. The apparatus determines a position of the receiver based on the received optical signals. The transmitter includes a light emitter for emitting optical signals of at least two flashing frequencies and a hollow hemispherical cover including two fixed-angle opaque regions, a variable-angle opaque region, and transparent regions located therebetween. The present invention further relates to a method of positioning with curved light surface.
