The invention relates to a multiple-
laser radar raster map merging 
system based on a pilotless automobile. The multiple-
laser radar raster map merging 
system based on the pilotless automobile comprises a one-line 
laser radar and a four-line laser radar, the two of which are mounted in front of the pilotless automobile, an eight-line laser radar mounted at the roof of the automobile, and a one-line laser radar mounted at the 
tail of the automobile; the laser radars are connected with a first industrial 
personal computer by use of a switch and by virtue of 
Ethernet; the data of the laser radar are transmitted to the first industrial 
personal computer by use of the switch and by virtue of the 
Ethernet, and the first industrial 
personal computer is used for analyzing and preprocessing the data; data are processed for different laser radars, respectively, and rasterization coding is performed on valid data and the coded values are transmitted to the first industrial personal computer in charge of data fusion by virtue of the 
Ethernet; next, data fusion is carried out by use of a raster map merging method and the rasterization coding is performed on the data, and finally, the coded values are transmitted to a second industrial personal computer by virtue of the Ethernet. The multiple-laser radar raster map merging 
system is used for solving the problem that the pilotless automobile and an assistant-driving automobile collide with a barrier, and therefore, the safety of the automobile in the driving process is improved.
