FIELD: possible use for finding objects or subjects and their movement direction.
SUBSTANCE: detecting device for finding subject or objects and direction of their movement includes system of radiation sensors for detecting electromagnetic radiation with wavelength of visible and/or invisible spectrum, which is reflected or emitted by subject or object, and estimation block, which is connected to a system of sensors, while estimation block is adapted for generation of signal, which corresponds to time-wise variation of radiation, detected by the system of radiation sensors, and is connected to recording device, which is adapted for storage of at least a part of variation signal and characteristic parameter, associated with this variation signal.
EFFECT: increased precision of detection of counting of objects or subjects.
