Surrounding Factors’ Influence on the Accuracy of the Digital Level and Total Station

Abstract

The digital level (SOKKIA SDL-30) and total station (SOKKIA CX-105) are highlighted as examples of digital surveying instruments. In this study, it is clarified how some surrounding factors can affect their efficiency such as vibration, sunlight, and its direction, temperature, and battery capacity. Through vibration testing as one of these factors ,both the digital level and the total station using the reflector-less were exposed to vibration up to 25 KHZ/Sec, the average and the standard deviations elevation error for the digital level increased by 2 times at 80 m distance , and the average and the standard deviations positioning error increased 3 times for the total station using the reflector-less total at 80 m distance between the instrument and bar code. 64.3% and 51.25% are the increasing ratios in average error for digital level and total station with reflector-less prism by testing the effect of sunlight and its position. The increase in temperature leads to an increase in the average error with 150 % and 66.6% for digital level and reflectorless total station. Finally, the lack of battery efficiency led to a shortage of accuracy of the Surveying Instruments.

Temperature Uncertainty Reduction Algorithm Based on Temperature Distribution Prior for Optical Sensors in Oil Tank Ground Settlement Monitoring

“…The tilt angle α is the angle between the normal line of the horizontal plane and the normal line of the surface. So, when calculating the projection, the corresponding projection angle can be expressed as follows: cosθ = cosβcosγsinα + sinβcosα (10) Especially, when the surface is a vertical plane:…”

“…This method offers the advantage of flexibility and safety, as it does not require contact measurements. However, it is vulnerable to environmental interferences like rain, snow, and low light conditions at night [10,11]. In order to overcome these limitations, researchers have utilized the hydrostatic leveling system (HLS) technique.…”

Transfer-Learning-Based Temperature Uncertainty Reduction Algorithm for Large Scale Oil Tank Ground Settlement Monitoring

“…This emphasizes the importance of prioritizing GS monitoring for large scale infrastructures. Currently, remote sensing methods, such as the use of Total Station, are commonly employed for GS monitoring, but they are susceptible to environmental interference and are labor-intensive [ 5 ]. Until now, there has been a lack of practical online GS monitoring techniques.…”
