  • Method and device for detection, identification and densimetric quantification of grain-eating insects in stocks of cereals
    Patent number: 6923064
    Abstract: A method and a device for detection, classification and densimetric quantification of grain-eating insects, of one or several families of insects simultaneously present, in stocks of cereals and the like, which includes detecting insects through noises and sound and/or infrasonic vibrations emitted by the insects. It also includes carrying out the following operations: recording the real noises in the stock, eliminating known spurious noises, detecting on the resulting envelope energy curve windows corresponding to energy peaks and determining therefrom the mean frequency, the spectral width and the global energy, comparing the mean frequency and the width of each of the windows to that of windows with similar known and listed characteristics, so as to operate a taxonomic classification, finally, comparing the mean frequency and the global energy of each of the windows, to those of windows with known and listed characteristics, to operate a densimetric quanitification.
