A method for inspecting a surface of a piece of nuclear power plant equipment, the method comprising the following steps: - scanning the surface with an acquisition field of a matrix array camera, the acquisition field moving relative to the surface at a movement speed; - acquiring, by means of the matrix array camera, a sequence of images of the acquisition field, the sequence being acquired with a certain acquisition frequency, each image including a first number of lines of pixels; the method being characterized in that it further comprises the following steps: - extracting, from the first acquired image, a first set of contiguous lines, the first set comprising a second number (n) of continuous lines of pixels, the extracted lines going from a rank r1 to a rank r1 + (n-1), rank r1 being between 1 and i-n+1, the second number (n) being between 2 and the first number and being such that n = v f ∗ h. with n the second number, h the height of a pixel, v the movement speed and f the acquisition frequency; - extracting, from each image of the sequence acquired after the first acquired image, a respective first set, the respective first set being formed by lines going from rank r1 to rank r1 + (n-1); - constituting a first final image of the surface by juxtaposing the first sets of lines extracted from each image, the final image covering the entire surface without interruption; - extracting, from the first acquired image, a second set of contiguous lines, the second set consisting of the second number of continuous lines of pixels, the extracted lines going from a rank r2 to a rank r2 + (n-1), rank r2 being between 1 and i-n+1, the lines of the second set being different from the lines of the first set; - extracting, from each image of the sequence acquired after the first acquired image, a respective second set, the respective second set being formed by lines going from rank r2 to rank r2 + (n-1); - constituting a second final image of the surface by juxtaposing the second sets of lines extracted from each image. - scanning the surface with an acquisition field of a matrix array camera, the acquisition field moving relative to the surface at a movement speed; - acquiring, by means of the matrix array camera, a sequence of images of the acquisition field, the sequence being acquired with a certain acquisition frequency, each image including a first number of lines of pixels; - extracting, from the first acquired image, a first set of contiguous lines, the first set comprising a second number (n) of continuous lines of pixels, the extracted lines going from a rank r1 to a rank r1 + (n-1), rank r1 being between 1 and i-n+1, the second number (n) being between 2 and the first number and being such that n = v f ∗ h. with n the second number, h the height of a pixel, v the movement speed and f the acquisition frequency; - extracting, from each image of the sequence acquired after the first acquired image, a respective first set, the respective first set being formed by lines going from rank r1 to rank r1 + (n-1); - constituting a first final image of the surface by juxtaposing the first sets of lines extracted from each image, the final image covering the entire surface without interruption; - extracting, from the first acquired image, a second set of contiguous lines, the second set consisting of the second number of continuous lines of pixels, the extracted lines going from a rank r2 to a rank r2 + (n-1), rank r2 being between 1 and i-n+1, the lines of the second set being different from the lines of the first set; - extracting, from each image of the sequence acquired after the first acquired image, a respective second set, the respective second set being formed by lines going from rank r2 to rank r2 + (n-1); - constituting a second final image of the surface by juxtaposing the second sets of lines extracted from each image.
