移动物理相机会导致相机目标点距离的宏记录错误问题。
Off-target distance is a key index for measuring quality of borehole trajectory, of which the key is to find out solution to coordinates of target points.
靶心距是衡量井眼轨迹质量的一个关键指标，计算靶心距的核心问题是求解入靶点的坐标。
The system of passive ranging SONAR makes use of the target noise received by the equipment which converts energy from one form to another to estimate the target distance.
被动测距声纳系统是利用换能器基阵接收的目标辐射（噪声）信号来估计目标距离。
Laser altimeter not only can precisely measure the target distance, but also extract characteristic information, such as inclination, roughness etc. from its echo signals. So they are applied widely.
激光测高仪不仅可以精确测量目标的距离，还能够从回波信号中提取倾斜度、粗糙度等特征信息，应用十分广泛。
