The invention provides a vehicle multi-laser radar calibration method and system, a terminal and a storage medium. The method comprises the steps of: parking a vehicle equipped with a plurality of laser radars on a flat road surface, setting one laser radar as a reference laser radar, and taking other laser radars except the reference radar as to-be-calibrated laser radars; measuring a point cloud between the reference laser radar and each of the to-be-calibrated laser radars; manually inputting calibration parameters into the to-be-calibrated laser radars, and using calibration software to perform registration; and displaying the movement trend of the registered point cloud, and ending the calibration when the point cloud of the to-be-calibrated laser radars and the point cloud of the reference laser radar have no obvious offset rotation and ghosting. In the calibration process, manual fine adjustment can be achieved by manually inputting initial calibration parameters; and fast matching of the point clouds
