METHOD AND APPARATUS FOR PRODUCING PIT WALL DEVELOPING IMAGE

摘要

PURPOSE:To produce the continuous developing image of all pit wall by a method in which all circumference of pit wall is photographed by a rotary mirror, set on a sonde vertically moving in a bored pit, and a television camera and sent to a developer on the land. CONSTITUTION:A depth sensor 5 is attached to a sonde 2 vertically moving in a state of being hung down from an elevator in a bored pit to send out electric signals at a fixed interval. A transparent window 18 in the direction of all circumference is provided to the sonde 2, a rotary mirror 14 covering a fixed range is provided in the axial direction, and a television camera 16 to be operated by driver 17 is set above the mirror 14. All the circumference of the pit wall 1 is photographed by the mirror 14 and the camera 16. On the land, a sonde controller 7, a television image receiver 6, a photographed image memory 11, a developed image memory 10, and a photographed image developer 12 are set. The developed image of all circumference is produced synchronously with signals from the depth sensor 5.
