The invention discloses a non-contact automatic tracking type ship model navigation sinkage measurement method. The method comprises the following steps: S1, establishing a two-dimensional coordinate system and a geodetic coordinate system of a laser receiving unit; s2, measuring the distance H0 between the origin of coordinates of the two-dimensional coordinate system of the laser receiving unit and the waterline of the ship model; s3, laser emitted by the laser emitting unit sequentially scans a group of pixels on the laser receiving unit, and the laser receiving unit obtains a vertical distance L from the group of pixels to the origin of coordinates of the two-dimensional coordinate system of the laser receiving unit after receiving a laser signal of the laser emitting unit; s4, after the laser receiving unit receives a laser signal of the laser emitting unit, obtaining an absolute elevation Z corresponding to a coordinate reading on the laser receiving unit at a certain moment, and designing a bottom elevation Z channel bottom of the channel model at the position of the laser receiving unit; and S5, calculating the deflection of the ship model. The method has the advantages that the sinkage of multiple measuring points at the same moment in the ship model navigation process is calculated, precision is high, and stability is high.

    本发明公开了一种无接触自动跟踪式船模航行下沉量测量方法,S1:建立激光接收单元的二维坐标系和大地坐标系;S2:测量激光接收单元的二维坐标系坐标原点与船模吃水线之间的距离为H0;S3:激光发射单元发射激光依次扫过激光接收单元上的一组像元,激光接收单元接收到激光发射单元的激光信号后得到这一组像元到激光接收单元的二维坐标系坐标原点的竖直距离L;S4:激光接收单元接收到激光发射单元的激光信号后,得到在某一时刻激光接收单元上的坐标读数对应的绝对高程Z,以及激光接收单元所处位置的航道模型设计底高程Z航道底;S5:对船模下沉量进行计算。本发明的有益效果是,计算船模航行过程中同一时刻多个测点的下沉量,精度高,稳定性强。
