IMAGE SYSTEMS FOR SMALL PIPE INTERNAL INSPECTION

摘要

PURPOSE: An image system for inspection an internal space of a small space is provided to enhance the accuracy of a pipe test by obtaining clear images with respect to an internal space of a curved portion of a small pipe. CONSTITUTION: An image system(100) for inspection an internal space inside a small space comprises a camera module(110), a lighting unit(120), an image signal amplifier(130), and a display device(140). The camera module is inserted into inside a small pipe and obtains images of a widespread area inside a small pipe with a wide angle lens or fisheye lens(111) and comprises a battery supplying power for an operation. The lighting unit is installed in a front surface of the camera module and lights the internal space of the small pipe. The image signal amplifier is connected to the camera module with an image cable and amplifies the obtained image signals. The display device receives the amplified image signals from the image signal amplifier, thereby displaying images to outside.
