AI Technical Summary
Existing laser measuring instruments suffer from amplified measurement errors due to changes in the air refractive index in high-temperature and high-dust environments, and current technologies have failed to effectively solve this problem.
By acquiring temperature and dust concentration data at measurement points, the air refractive index is calculated and a correlation is established. The measurement errors caused by temperature and dust are quantified, and an error correction module is used to correct the measurement distance.
This invention improves the measurement accuracy of laser measuring instruments in high-temperature and dusty environments, eliminates the interference of air refractive index changes on the measurement, and enhances measurement accuracy.
