Embodiment Construction
[0050] The present invention is described in detail below with reference to accompanying drawing and embodiment:
[0051] attached Figure 1-8 It can be seen that a method for generating a cylindrical panorama of a 4-way borehole wall video comprises the following steps:
[0052]In step s801, four cameras with the same focal length are selected, and the four cameras are connected into one to form a camera group; they are placed perpendicularly to each other in the same plane with their backs to the same center point, and the shooting direction is perpendicular to the cylindrical surface where the wall of the borehole is located; The camera group is placed in the geological exploration hole;
[0053] In step s802, the camera group moves longitudinally for a set distance along the hole wall;
[0054] In step s803, four single image files are simultaneously extracted at a certain moment during the movement of the drilling video camera;
[0055] In step s804, geometric correcti...
