The invention provides a measurement and 
processing integrated 
laser leveling 
polishing method which comprises the steps that a workpiece is clamped; a two-dimensional 
laser displacement sensor and the workpiece are controlled to make relative translation movement, and a coordinate matrix of uniform measurement points is obtained; a 
galvanometer scanning 
system is controlled to scan a to-be-polished part of the surface of the workpiece according to the set scanning speed, and a new coordinate matrix of the uniform measurement points of the to-be-polished part of the surface of the workpiece is obtained after 
laser scanning; 
delta is calculated according to the function that 
delta is equal to z'max-z'min, if 
delta is less than or equal to the target smoothness of the workpiece, the operation is completed; otherwise, a 
laser scanning grid chart of the surface of the workpiece is constructed, and each grid in the 
laser scanning grid chart is endowed with a weight number k; the 
galvanometer scanning 
system is controlled to carry out k times of scanning 
processing on each grid in the 
laser scanning grid chart according to weight number k. Dynamic adjustment of 
processing parameters is realized and different processing parameters are used in different stages, so that the thickness of a material removed by laser scanning at every time can be increased, the leveling speed can be increased, and the processing efficiency and the processing precision can be improved.
