Immersive projection surrounds live audiences from various layers, can comprehensively cover the visual angles of the audiences, and the immersive immersion feeling is not realized by common projection and is applied in more and more fields.

For an immersive projection system, as more large-scale equipment is used and the requirement on the degree of optical refinement is high, the whole construction period is usually long, and the efficiency is generally low. Especially, when splicing the curtains, the curtain units are required to be spliced seamlessly, for example, when splicing the spherical curtain, the curtain units at the same latitude are required to be arranged on the same horizontal line. Namely, in the process of adjusting the circular screen geometric image, the circular screen weft needs to be accurately positioned, and the image geometric line is superposed with the positioning line.

At present, commonly used calibration devices are for example laser levels, theodolites or total stations, etc. The laser level can form a red (or green) line in a projection area (only a position with the same height as the height of the instrument) and guide an image laying area, but the laser level has the defect that the level needs to be erected at the same height as the position of laying a curtain, and the erection is difficult. Theodolite and total station are high technology measuring instruments, and it erects on the ground, and the accessible sets up throws red setpoint at required high position, but the shortcoming can only throw an instruction point on the weft of ring curtain appointed height, can not form continuous instruction point, and is very inconvenient in actual operation, inefficiency. At present, there is little dedicated equipment for image geometry debugging, especially in immersive curtain splicing.
