The invention discloses a driving area importance weight distribution modeling method oriented to intelligent vehicle laser radar processing. A top-view grid map centered on an intelligent vehicle isconstructed and a distance and direction of each grid relative to the vehicle are calculated; an area-of-interest model of a driver based on a driving speed and a front wheel turning angle is established, main areas of interest and secondary areas of interest of the driver in different driving states are obtained, and a regional importance weight distribution model is established based on prior information of an excellent driver; and then according to the established top-view grid map, the area-of-interest model of a driver, and the importance weight distribution model, an importance weight ofeach grid is calculated, so that difference processing is carried out on radar point cloud data, the area data with the high importance weight are processed in priority and the area data with the lowimportance weight are processed simply. Therefore, the data processing efficiency is improved, so that the real-time performance of the intelligent vehicle's perception of external environment information is enhanced.
