1. can improve a method for the time difference range finding of moveable detection efficiency, comprise:

  • Launch invisible light detecting object;

    Record the time interval that this invisible light arrives sensor after this object reflection;

    The method is characterized in that and also comprise;

    This time interval is utilized to estimate the measuring distance of this object;

    The measuring distance of this object is utilized to determine size and the scope of activities of this object;

    AndAccording to the measuring distance of this object, size and scope of activities, adjust position and size that this sensor corresponds to the emphasis sensing range of this object;

    Wherein this sensor is greater than this sensor at the outer number of pixels sensed of this emphasis sensing range at the number of pixels that this emphasis sensing range senses.
