A device for assisting the piloting of a rotorcraft in order to enable a rotorcraft to be piloted during an approach stage preceding a stage of landing on a landing area (14, 14') intended for a rotorcraft, said landing area being a helipad, heliport or helideck, said device comprising: a display member for displaying various images respectively representative of a plurality of types of landing area to be looked for by said device, preselection means for preselecting, from the various images respectively representative of a plurality of types of landing area, a type of landing area to be looked for by said device, said preselection means being of the touch type and arranged directly on a display surface of said display member, said preselection means being actuated by a crew of said rotorcraft; at least one camera (3, 3') for producing a plurality of images of the environment of said rotorcraft situated forward of said rotorcraft in a posterior-anterior direction Dx of said rotorcraft, said at least one camera (3, 3') being oriented to produce said plurality of images of the environment of said rotorcraft along a line of sight (20, 20'), said line of sight (20, 20') being oriented at least along said posterior-anterior direction Dx of said rotorcraft; processing means for identifying in at least one image, from among said plurality of images, at least one looked-for landing area (14, 14') corresponding to the type of landing area preselected via the preselection means, said display member being configured to display at least one image representative of said at least one looked-for landing area (14, 14'), selection means enabling the crew of said rotorcraft to select a desired landing area from among said at least one looked-for landing area (14, 14'), said processing means making it possible to identify in said at least one image, from among said plurality of images, whether said at least one desired landing area includes an occluding element and then to display an information message on said display member with said image representative of said at least one desired landing area including said occluding element, a control unit for generating a control setpoint enabling said rotorcraft to be automatically piloted horizontally towards said desired landing area. preselection means for preselecting, from the various images respectively representative of a plurality of types of landing area, a type of landing area to be looked for by said device, said preselection means being of the touch type and arranged directly on a display surface of said display member, said preselection means being actuated by a crew of said rotorcraft; at least one camera (3, 3') for producing a plurality of images of the environment of said rotorcraft situated forward of said rotorcraft in a posterior-anterior direction Dx of said rotorcraft, said at least one camera (3, 3') being oriented to produce said plurality of images of the environment of said rotorcraft along a line of sight (20, 20'), said line of sight (20, 20') being oriented at least along said posterior-anterior direction Dx of said rotorcraft; processing means for identifying in at least one image, from among said plurality of images, at least one looked-for landing area (14, 14') corresponding to the type of landing area preselected via the preselection means, said display member being configured to display at least one image representative of said at least one looked-for landing area (14, 14'), selection means enabling the crew of said rotorcraft to select a desired landing area from among said at least one looked-for landing area (14, 14'), said processing means making it possible to identify in said at least one image, from among said plurality of images, whether said at least one desired landing area includes an occluding element and then to display an information message on said display member with said image representative of said at least one desired landing area including said occluding element, a control unit for generating a control setpoint enabling said rotorcraft to be automatically piloted horizontally towards said desired landing area.
