摘　　要：针对民用起重作业船舶由于波浪等引起的升沉检测问题,提出了基于机器视觉的船舶升沉检测方法。首先建立船舶升沉检测系统架构,通过双目立体视觉三维测量方式,对目标位置的垂直高度进行测量,之后对检测图像进行系列处理,最后给出船舶升沉值对应的数据处理流程图,并将该方法进行应用。结果表明,双目测距最大误差2.08%,系统安装调试方便,可为实现波浪补偿提供实时数据,满足起重作业的安全要求。This paper proposes a ship heaving measuring way based on machine vision to solve the ship heaving measurements of civil lifting operation under the influence of wave.The ship heaving measuring architecture is built and the vertical height measurement of object position is done through binocular stereo vision of three-dimensional measurements.The detection images are processed and the data flow process diagram corresponding to the ship heaving value is given and the way is applied.It is shown that in the conclusion,the inaccuracy is less than 2.08%,and it is easy to install and debug the system,and provides real time data for wave compensation and satisfy the security requirement of lifting operation.
