Abstract

The invention relates to a liner imaging device (1), comprising a body (2) and at least two cameras (3) provided on an outer surface (4) of the body (2). The at least two cameras (3) are arranged substantially in the same plane at a predetermined distance from each other, such that combined pictures from the at least two cameras (3) cover the complete liner circumference. The invention also relates to a method for establishing an image an inner wall of a liner (7).
