Abstract (en)
[origin: CA3231635A1] A method for acquiring multispectral images and panchromatic thumbnail images by means of a matrix-array sensor installed in a carrier travelling above a scene and covered with a filter having a panchromatic filtering band followed by at least two spectral filtering bands, the panchromatic and spectral filtering bands being parallel and extending in a direction that is substantially orthogonal to the movement of the carrier, the method comprising the following steps: a. as soon as the scene is within one of the filtering bands of the filter, acquiring a multispectral image at least through the two spectral filtering bands; b. transferring the multispectral image; c. acquiring a panchromatic thumbnail image only through the panchromatic filtering band; d. transferring the panchromatic thumbnail image; e. as long as the scene is not within another of the filtering bands, repeating steps c) and d); and f. repeating steps a) to e) until a multispectral image of the scene through each filtering band is obtained. An acquisition device and a vehicle using said method.
