Now the industrial endoscope has been combined with the advanced video imaging technology, and the software and hardware are very excellent, so it can feed back the content and picture captured by the lens to the screen at the time of detection, so that we can find the problem, find the problem and find the solution at that time. In this case, it is very good to use the endoscope to detect the quality and safety of the object, and the higher the accuracy of the endoscope, the better the detection effect.

工业内窥镜在现代工业社会中应该属于一种非常实用的检测类精 密仪器，而判断这个仪器的优劣性的一个重要标准就是它的测量精度。在判断内窥镜的可靠性、优良性的时候也是需要看它的测量精度的。一般来说优良的内窥镜应该做到精度高而且准确的程度。当然，采用内窥镜做检测作业的时候，内窥镜的精度还会受到一些外部环境的影响。

Industrial endoscope should be a kind of very practical safety detection precision instrument in modern industrial society, and an important standard to judge the advantages and disadvantages of this instrument is its measurement accuracy. When judging the reliability and excellence of endoscope, we also need to look at its measurement accuracy. Generally speaking, an excellent endoscope should have high precision and accuracy. Of course, the accuracy of endoscope will be affected by some external environment when the endoscope is used for detection.
             

，被检测物品的管径大小，粗糙程度等等会直接影响到工业内窥镜的检查精度。管径太小的内窥镜无法探入其中自然谈不上精度检测，而设备粗糙不够精细给内窥镜造成的障碍也很多，而且容易对探测结果产生干扰，让内窥镜设备无法吸收到镜头传递回来的回波信号，另外镜头探入探出也十分的不方便。

First of all, the diameter and roughness of the detected object will directly affect the inspection accuracy of the industrial endoscope. If the diameter of the endoscope is too small, it will not be able to detect the accuracy. However, if the equipment is rough and not precise enough, there will be many obstacles to the endoscope, and it is easy to interfere with the detection results, so that the endoscope equipment can not absorb the echo signal transmitted by the lens. In addition, the lens detection is also very inconvenient.

工业内窥镜使用的环境如果是带有大量腐蚀性物质，或者是物品内部有粗糙颗粒对内窥镜磨损很大的话，不仅无法保证检测精度，还会给内窥镜造成非常大的损坏。还有就是有电磁干扰或者是管道内有沉积物等等都会影响到检测精度。

If there are a lot of corrosive substances in the environment of industrial endoscope, or if there are coarse particles inside the articles, it will not only fail to ensure the detection accuracy, but also cause great damage to the endoscope. There is electromagnetic interference or sediment in the pipeline and so on will affect the detection accuracy.
