ABSTRACT:
An apparatus for identifying the condition of a conveyor belt (6) has a capturing device (12) which can be used to capture two-dimensional images (B) of successive belt sections (15) of the conveyor belt (6) during operation of the conveyor belt (6). The capturing device (12) and the evaluation device (13) have a data-processing connection, so that the captured images (B) can be transmitted to the evaluation device (13). The evaluation device (13) compares the images (B) transmitted to it with two-dimensional reference images (R) which are associated with the belt sections (15), determines at least one statement about the condition of the belt on the basis of the comparison, and outputs the statement about the condition of the belt.
