1. An intelligent hoisting method for a bridge deck crane system, comprising:
obtaining an alignment height at an edge of an already installed segment, and deriving a first splicing height at a first position and a second splicing height at a second position of a segment to be installed based on said alignment height, wherein the distances between the first and second positions and the edge of the installed segment differ;
hoisting the segment to be installed and continuously monitoring a first real-time height at the first position and a second real-time height at the second position until the first real-time height equals the first splicing height or the second real-time height equals the second splicing height;
if the first real-time height equals the first splicing height, adjusting a hoisting point of the segment to be installed to move towards the first position while continuously adjusting a hoisting height to maintain the first real-time height equal to the first splicing height until the second real-time height equals the second splicing height;
if the second real-time height equals the second splicing height, adjusting the hoisting point of the segment to be installed to move towards the second position while continuously adjusting the hoisting height to maintain the second real-time height equal to the second splicing height until the first real-time height equals the first splicing height.
