Background

The work of measuring the elevation of a ground point is called leveling measurement, and is widely applied to engineering measurement, industrial measurement, geodetic measurement and the like at present because the measurement precision of the leveling measurement is relatively high.

The level applied at present can be divided into an optical level and an electronic level according to the principle, wherein the electronic level is formed by adding a spectroscope, a photoelectric detection device and other parts in the optical path of an instrument telescope, and an optical, mechanical, electrical and information storage and processing integrated leveling system is formed by adopting a bar code division leveling rod and an image processing electronic system.

The auxiliary tools commonly used in electronic level measurements are leveling rods and leveling pads, and the following automatic electronic reading methods are used for measurement, for example: correlation, geometric and phase methods.

The electronic level has the characteristics of high measuring speed, objective reading, low labor intensity, high operation precision, convenience in inputting measured data into a computer and easiness in realizing the integration of internal and external industries in leveling measurement, and is widely used.

But the electronic level has the shortcoming that the requirement on the illuminance of the leveling rod is high during reading, and reading cannot be performed under the conditions of low illuminance, uneven light or shadow on the bar code ruler.

In actual work, part of the measurement work must be performed in nighttime environments, such as mine measurement, settlement observation of urban underground railway lines, high-precision measurement of elevated railways, and bridge dynamic and static load tests and highway settlement observation performed in nighttime environments with rare vehicles due to reduction in measurement precision caused by vibration generated by vehicles in the daytime. Because the illumination condition at night often cannot meet the requirement, the leveling instrument cannot identify the bar code on the leveling rod; meanwhile, the leveling rod must be moved in the actual measuring process, and when the distance from the leveling instrument is far, the high-power lighting mode or the lighting mode of the flashlight is not suitable for observation.
