Abstract: To provide a method of measuring a state of concrete capable of easily determining or measuring deterioration of the concrete without using a spectroscopy while maintaining the estimation accuracy. The method of the present disclosure emits an irradiation light to the concrete, the irradiation light including a wavelength range of near infrared light related to concrete measurement; and receives a reflection light of the irradiation light P reflected on the concrete. The method determines at least five wavelengths λ1 to λ5, λ6 to λ10, different from each other by PLS regression analysis within a wavelength range of 900 nm to 2500 nm of absorption spectrum, and estimates a degree of neutralization of the concrete caused by calcium hydroxide and a concentration of chloride ion.

Abstract: A surveying device body includes a distance measuring section to measure a distance to the measurement target, an optical axis deflector that deflects distance measuring light with respect to a reference optical axis, a measurement direction imaging section that obtains an observation image, and an attitude detector that detects an incline of the surveying device body. A computation controller displays a portion of the observation image on the display unit, computes a direction angle of the distance measuring optical axis on the basis of a detection result of the attitude detector and a deflection angle of the distance measuring optical axis with respect to the reference optical axis, and measures the measurement target on the basis of the direction angle and a distance measurement result of the distance measuring section using a reference point as a reference.

Abstract: A technique for calculating charge in accordance with a state of use of a user in a rental business of total stations is provided. A total station includes a positioning unit, an operation receiving unit, a positioning mode selector, and a counter. The positioning unit performs positioning by using pulsed laser light. The operation receiving unit receives operation of a user. The positioning mode selector selects one of a first positioning mode and a second positioning mode on the basis of operation of the user to the operation receiving unit. In the first positioning mode, positioning is performed at a specific point at a relatively small laser wave number. In the second positioning mode, positioning is performed at a specific point at a relatively large laser wave number. The counter counts up each of the selected times of the first positioning mode and the second positioning mode.
