What are the reasons that affect the accuracy of the handheld video endoscope? The handheld video endoscope can detect objects that we cannot observe with the naked eye to see if there is a problem. The handheld video endoscope uses video imaging technology to extend the endoscope into the object, and then take pictures through the lens. In use, the measurement accuracy may be inaccurate due to some factors. So, what are the reasons that affect the accuracy of the handheld video endoscope?

1. The size of the radius of curvature of the workpiece:

If the pipe diameter of the workpiece is too small, it cannot be measured. We can reduce the workpiece curvature of the equipment to help the equipment measure better. A special probe with small diameter can be used to measure the curved surface material of the pipeline more accurately and enter the inner part of the equipment, thereby improving the detection accuracy.

2. Symmetry of casting structure:

The working accuracy of the handheld video endoscope may also be affected by the structure of the casting. If the structure of the casting is not symmetrical or the grains are coarse, it is easy to affect the normal detection of the equipment. If there is a lot of corrosion on the surface of the measured object, it will also seriously affect the measurement effect.

3. The surface roughness of the workpiece:

The roughness of the workpiece surface of the handheld video endoscope will affect the observation efficiency of the device. The reflected echo of the device is low. If the surface roughness of the object is too large, the device cannot absorb the echo signal. Researchers can treat the surface by sanding, grinding, filing and other methods to reduce the roughness of the product surface.
