  • Device for assisting in the detection of objects placed on the ground from images of the ground taken by a wave reflection imaging device
    Patent number: 10228812
    Abstract: A device for assisting with the detection of a sought object on the ground, said object having a first preset height, comprising: a display device configured to display an image (12) generated from echoes measured by a device for imaging reflected waves, the image (12) representing the intensities of echoes generated by the observed zone and extending at least along a distance axis (d) representing the oblique distances separating the reflected-wave imaging device from echo-generating reflectors, the display device allowing a cursor (14) to be displayed superposed on said image on said screen; and a computational module configured to determine an expected length (w), along the distance axis (d), of an expected shadow (19, 20) projected in the image (12) by the sought object assuming that the sought object is positioned at a sighted position on the ground corresponding to the position of the observed zone associated with a position (P) designated by the cursor (14), the cursor (14) comprising at least one g
