Abstract
A method for inspecting a surface (12) of a piece of nuclear power plant equipment includes scanning the surface (12) with an acquisition field (20) of a matrix array camera (14). The acquisition field (20) moves relative to the surface (12) at a movement speed. The method also includes acquiring, by means of the matrix array camera (14), an image (22) of the acquisition field (20), with a certain acquisition frequency. Each image (22) includes a first number of lines of pixels. The method also includes extracting, from each image (22), a first set of lines, the first set comprising a second number of continuous lines of pixels, the second number being between 2 and the first number; and constituting a final image (32) of the surface (12) by juxtaposing the lines extracted from each image (22). The movement speed, the acquisition frequency, the first number of lines and the second number of lines are chosen such that the final image (32) covers the entire surface (12) without interruption.
