Manual image measuring instrument 

1. Precise measurement and high accuracy: The degree of intelligence of manual image measuring instrument is low. Especially in terms of software functions, intelligent image scanning and calculation cannot be realized, but manual extraction depends on manual judgment: each person manually extracts according to their own human eye judgment, which results in large errors due to different measurement results. Therefore, in addition to its own accuracy limit, the errors caused by human operation also lead to the randomness and poor accuracy of the measurement results of the manual image measuring instrument. The automatic image measuring instrument has made rigorous large data calculation for primitive edge extraction, image scanning, data analysis, etc. through powerful computer algorithms, which can provide users with more automatic and standardized operation steps and methods, avoid manual operation errors of the image measuring instrument, and ensure higher and more consistent measu…
