Abstract
A method, non-transitory computer readable medium and a system that includes a fuzzy logic module arranged to apply a fuzzy logic algorithm for calculating, in response to received echoes that are received by a receiver, confidence levels of origins of received echoes; wherein the received echoes are reflected or scattered from the origins; and a volume calculator that is arranged to calculate a volume of the content in response to (a) estimated locations of the origins, and (b) the confidence levels of the origins.
Claims30
A system for estimating a volume of a content of a bin, the system comprising:
- at least three acoustic transceivers that are non-collinear;
- wherein a transmitter of an acoustic transceiver of the at least three acoustic transceivers is configured to transmit pulses of radiation towards an interior of the bin;
- wherein a receiver of at least one of the acoustic transceivers is configured to receive received echoes of the pulses of radiation;
- a fuzzy logic module arranged to apply a fuzzy logic algorithm for calculating, in response to the received echoes, confidence levels of origins of received echoes;
- wherein the received echoes are reflected or scattered from the origins;
- and
- a volume calculator that is arranged to calculate the volume of the content in response to (a) estimated locations of the origins, and (b) the confidence levels of the origins;
- and
- wherein the volume calculator is arranged to classify a received echo as a false echo when an origin of the receive echo is positioned outside the bin.
A computerized method for estimating a volume of content of a bin, comprising:
- transmitting by a transmitter of an acoustic transceiver of the at least three acoustic transceivers that are non-collinear, pulses of radiation towards an interior of the bin;
- receiving by a receiver of at least one of the acoustic transceivers, received echoes of the pulses of radiation;
- applying, by a fuzzy logic module, a fuzzy logic algorithm for calculating, in response to the received echoes, confidence levels of origins of received echoes;
- wherein the received echoes are reflected or scattered from the origins;
- calculating, by a volume calculator, the volume of the content in response to (a) estimated locations of the origins, and (b) the confidence levels of the origins;
- and
- classifying a received echo as a false echo when an origin of the receive echo is positioned outside the bin.
A non-transitory computer readable medium that stores instructions that cause a computerized system to:
- apply a fuzzy logic algorithm for calculating, in response to received echoes that are received by a receiver of at least one acoustic transceiver out of at least three non-collinear acoustic transceivers, confidence levels of origins of received echoes;
- wherein the received echoes are reflected or scattered from the origins;
- calculate a volume of a content of a bin in response to (a) estimated locations of the origins, and (b) the confidence levels of the origins;
- and classify a received echo as a false echo when an origin of the receive echo is positioned outside the bin.
