A cable inspection apparatus includes an image capturing device and a determination device. The image capturing device includes a ring camera frame and a plurality of cameras mounted on the ring camera frame and distributed at intervals on a circumference of the ring camera frame. The cameras simultaneously capture images of a cable to be inspected extending through the ring camera frame from a plurality of different angles. The determination device determines whether or not a portion of the cable is qualified according to the images.
