摘要:
A piece of airborne optoelectronic equipment (EO, EO1, EO2) comprising: - at least one image sensor (CI1, CI2), designed to acquire a plurality of images (IMR1, IMR2) of a region (RS) flown over by a carrier (PO1, PO2) of said equipment; and - a data processor (PD) configured or programmed to receive at least one so-called acquired image and transmit same to a display device (EA); characterised in that said data processor is also configured or programmed to: - access a database (BD) of images of said overflown region; - extract, from said database, information making it possible to synthesise a virtual image (IMV) of said region that is viewed by an observer located at a predefined observation point and watching, with a predefined field of view, along a predefined line of sight; - synthesise said virtual image and; - transmit same to said or to another display device. The invention also relates to a method for using such a piece of equipment.
摘要:
The invention relates to a method for detecting a stream of electromagnetic pulses emitted, according to a predefined occurrence law, in a scene observed using a detection system (22) comprising a matrix detector (30) and a unit (32) for processing signals comprising the electromagnetic pulses. The method includes the following steps: acquiring and transmitting the signals from the matrix detector (30) to the processing unit (32); for each pixel of the detector (30): calculating a subtraction signal between two signals acquired during two consecutive time windows of the same length, calculating a signal for accumulating the subtraction signals spaced apart in time by an interval defined by the predefined occurrence law, and thresholding the accumulation signal, the laser pulse being detected if the accumulation signal is greater than a predetermined threshold for at least one pixel; and locating the electromagnetic pulse detected in the observed scene from the coordinates of the pixel including the detected electromagnetic pulse.
