Problems solved by technology

In conventional technology, cameras are used to monitor the water meter verification assembly line and production line. This method cannot accurately obtain the abnormal track of the water meter during its travel.
In another application scenario in the prior art, after the water meter verification manufacturer completes the mass production of water meters, the rotation of the water meter pointer and whether the appearance display is normal are important indicators for judging whether the quality of the water meter is qualified. If each water meter is manually observed method, it needs to consume a lot of manpower, and the test efficiency is low
