An optical device (1) is described for capturing images, in a 360° field, by digital stitching of three images. The device includes three optical groups (2, 3, 4) having a longitudinal axis (20, 30, 40) for obtaining the three images. Each optical group (2, 3, 4) includes a head lens (21, 31, 41) followed by several lenses (211, 311, 411) on the same longitudinal axis (20, 30, 40) to project rays towards an image sensor (22, 32, 42). The three optical groups (2, 3, 4) are interlinked around an imaginary axis of rotation (5), and positioned to overlap in a triangular configuration, in the direction of the imaginary axis of rotation, the longitudinal axes (20, 30, 40) being inclined with respect to a plane orthogonal to the imaginary axis of rotation to allow the interlinking of the optical groups.
