BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an image detection system, and more particularly to an image detection system for detecting conditions inside a hole or a tube.

2. Description of the Related Art

FIG. 1A to 1Care schematic diagram of a conventional detection process for a large-diameter tube. As shown, the technology performs detection for a large-diameter tube by using an endoscope, an endoscope lens is extended to the inside of the tube (as shown inFIG. 1AandFIG. 1B), and an optical fiber cable12of the endoscope11is flexible. However, during the operation of the large-diameter tube10, as the endoscope11enters the tube10while the endoscope11progresses horizontally in the large-diameter tube10, the flexible optical fiber cable12may turnabout in place (as shown inFIG. 1C) due to the friction between the optical fiber cable12and the wall of the tube, such that the optical fiber cable12cannot move forward any further, hence affecting the detection operation inside the tube. Further, also due to the flexibility of the optical fiber cable12, the endoscope lens connected to the optical fiber cable12may be affected by weight during the inspection of the large-diameter tube10, in a way that the lens drops and cannot be accurately positioned because of the weight, and the distance between the endoscope11and the surface inside the tube cannot be kept fixed, further resulting in a blurry detection image.

FIG. 2shows a schematic diagram of an auxiliary inspection device for an endoscope with a large-diameter tube of the Taiwan Patent No. M359306. As shown in the drawing, the device includes a handle assembly20and a lens assembly30. The handle assembly20includes a rod body21and at least two fixing assemblies22fixed at the rod body21. The lens assembly30includes an endoscope lens31, a support portion32for fixing the endoscope lens31, and at least one node portion33. The rod body21is for holding of an operator and supporting the endoscope lens31. The rod body21is kept near the position of the central axis of the large-diameter tube by the fixing assemblies22. The first node of the node portion33is connected to the support portion32and the last node is disposed on the handle assembly20, and the capturing angle and focus of the endoscope lens31are adjusted through the node33. The configuration above solves the issue of the optical fiber cable being incapable of moving forward or being twisted as a result of friction as described above. However, the length of the rod body also needs to be increased as the test distance increases, such that a user may not be able to hold the rod body properly or full-range inspection may not be effectively achieved because of the rod body.
