Abstract

Unified automotive safety technology is the tendency of developing automotive safety technologies. The occupant protection performance of conventional automotive passive safety technology can be further improved by cooperating with active sensors such as millimeter-wave radars and cameras. The view of interest in automotive passive safety technology is nearer than that in active safety technology. A calibration method for radars and cameras was developed using vehicle longitudinal symmetry plane as a datum to more accurately detect and locate in automotive passive safety application. Calibration parameters were obtained, with the coordinate transformation relationship between the two sensors being developed. Validation tests show that the radar and the camera in this method have good measurement accuracy, and the target location can be transformed into picture coordinate accurately. This method can provide reliable data for automotive safety systems.
