A method of producing a known fixed spatial relationship between a laser scanner and a digital camera for traffic surveillance

摘要

A method for establishing a known fixed spatial relationship between a laser scanner and a digital camera for traffic monitoring, wherein the laser scanner axis and the optical axis of the digital camera are aligned only roughly and the spatial relationship between a defined by the position of the laser scanner and alignment of the laser scanner axis scanner coordinate system (1 ) and a camera coordinate system (3) defined by the position of the digital camera and alignment of its optical axis are computationally determined based on the measured values and the image of a vehicle passing through the monitored area.
