Abstract
One or more types of laser scanner apparatuses perform object detection by emitting laser pulses and detecting corresponding reflected pulses by correlating a digitized detection signal against a correlation template representing a characteristic signal pulse. Regions of the digitized detection signal exhibiting high correlation with the template correspond to reflection pulses caused by backscattering of the emitted laser pulses. A calibration system and corresponding calibration method improve detection operations by such laser scanner apparatuses by producing a high-resolution correlation template. Among the several advantages associated with the system and method is the ability to produce correlation templates of high resolution, without requiring any increase in the base sampling rate of the digitizers used by the calibration system and the laser scanner apparatuses for digitizing their respective detection signals.
