Patent ID: 7460980

Claim:
A method for operating a drivable pipe inspection apparatus comprising: providing a camera head swivellable about two orthogonal axes, said camera head having two optical cameras, one of which being a fisheye camera, the other one being a high resolution zoom camera; providing remote control motors for causing whose swivel movements of the cameras about the two orthogonal axes; measuring at least one swivel movement by means of a rotational angle transducer whose measurement signal can be displayed and evaluated on a monitor as image information; creating two sets of image information, of which a first set contains image information of a developed pipe circumference and a second set contains information of details of a pipe surface; automatically assigning the two information sets to one another at least with respect to a location in and an angular position of a pipe section; and the assignment of the second set of information to a location of the developed pipe circumference being done through a software embodied on a computer readable medium supported permanent linkage of position coordinates of the location and angular position of the pipe section, with the obtained image information.
