Trolley camera position detecting apparatus
A trolley camera position detecting apparatus of the present invention is configured so that a girder camera is installed on a girder, a clinometer is installed to the girder camera, a constant value &dgr;o relating to a horizontal travel amount &dgr;g of a girder reference point is measured in advance by using the output values &dgr;cg and &dgr;kg, and on the other hand, the horizontal travel amount &dgr;g is calculated by using the output values &thgr;cg and &dgr;kg of the girder camera and clinometer, which are measured every moment, and the constant value &dgr;o, and the position of a trolley camera with the rail center being a reference is corrected by using the horizontal travel amount &dgr;g.
