precision of point measurement

Important factors include the sampling rate, the zero point of pressure sensor, and the correct calibration of sensor, the revised program and algorism may improve the precision of measurement.

如实时设定的实际采样率和压力传感器零点、对传感器校准与标定的正确性等诸因素均可影响实测数据的精度。

Reovering the feature point and feature line is the basic in the computer visual inspection, the high-precision is asked in the measurement of industry.

特征点、特征线的提取是计算机视觉检测的基础，特别是在工业检测中要求很高的精度。

Results indicate that the DSCM overcomes the shortcomings of traditional mechanical point measurement method, and its precision was enough for similarity simulation experiment.

结果表明，数字散斑相关方法不仅克服了传统机械点测量方法的某些缺点，同时具有较高的精度，可用于相似材料的模型实验。
