摘　　要：相对于传统水下光电成像,水下激光扫描成像系统可以获得更远的作用距离和更好的图像质量。基于激光同步扫描技术,提出了水下运动目标的测距方法,并对测距误差进行了定量分析,为水下目标测距提供了一个新的途径。其中单探测头水下激光扫描测距方法能对合作目标进行测距,在近距离时具有较高的测距精度,双探测头水下激光扫描测距方法能对非合作目标进行测距,在较远距离上能获得较高的测距精度。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 quantificationatly, 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.
