The present application discloses a position acquisition method and a position acquisition apparatus. The method includes: selecting at least one group of N effective devices from known devices that transmit signals to a target device or known devices that receive signals transmitted by the target device; adjusting a numerical value of a conversion scaling factor with respect to each group of N effective devices, and seeking a corrected value of the conversion scaling factor; wherein the conversion scaling factor is used to convert a signal intensity of the signal transmitted by the effective device towards the target device or the received signal transmitted by the target device into a distance; and calculating and acquiring a position of the target device by using at least one corrected value of the conversion scaling factor acquired. Position acquisition accuracy is improved through the embodiments of the present application.
