Abstract: The multi-line laser three-dimensional imaging method and system is based on a random lattice. A multi-line laser is used and combined with a rotating mechanism to realize a large-view-field rapid scanning effect, such that the working efficiency is improved by orders of magnitude, and the deployment difficulty of the system is reduced. Due to the fact that within an imaging range, pattern features of the random lattice of each local area have uniqueness, a plurality of laser lines are extracted, position sequence numbers are distinguished, and noise points are reduced through mutual verification of the pattern features of the random lattice between adjacent images, such that the quality of three-dimensional point cloud data is greatly improved. The method and the system can be applied to industrial applications, such as disorderly grabbing, feeding and discharging, unstacking and stacking, logistics sorting and the like.
