Laser Scanning Range-Finding Method for Underwater Moving Object

Underwater laser scanning imaging system can get images of higher quality from further distance relative to traditional underwater optical imaging system.Based on laser synchronous scanning technology,a range finding method for underwater moving object is proposed,ranging accuracy is also analyzed quantificationally,and this comes to be a new approach for underwater object range finding.The laser scanning underwater range finding method with single imaging sensor can find the range to cooperative object and has good ranging accuracy in near distance,and the laser scanning underwater range finding method with double imaging sensors can find the range to non-cooperative object and even has good ranging accuracy in farside distance.
