Well, I am sorry to say no. As you all know the theories of triangles.The distance the laser measures is certainly not what you need. The reading is the length of longest side of a triangle.So no matter how precise of a laser ranging on a manhole camera is, it can only give you a general idea where the sewer lines has a defect. If you use the reading to decide where to dig a trench, it will work not too bad. But to drill a hole from a reliner to a lateral is another story.You will need very precise measurement of a pipe section underground.
