Abstract
A method for constructing a lamp chain circling model comprises: obtaining an on-site image of a lamp chain that spirally circles around an external carrier, determining a planar spatial position of each front lamp bead of the lamp chain in an image view space, and determining a conical model of the external carrier; unfolding the conical model into a sector-shaped reference region in the image view space; arranging each circle of rear lamp beads on the surface of the sector-shaped reference region according the missing number of each circle of rear lamp beads on the lamp chain, and determining sector-shaped spatial positions of all the lamp beads in the sector-shaped reference region; mapping the sector-shaped spatial positions of the lamp beads on the surface of the sector-shaped reference region to corresponding stereoscopic spatial positions in a modeling space, and obtaining the lamp chain circling model.
