Title:
SURVEY SYSTEM
Document Type and Number:
Japanese Patent JP2023050332
Kind Code:
A
Abstract:
To provide a survey system with which it is possible to easily measure a deviation from or an uneven state of the set height of a measurement object plane, and carry out construction work, such as concrete pouring work or ground leveling work, in parallel with the measurement of the height or uneven state of the plane to be set.SOLUTION: Provided is a survey system comprising a height measurement device 1 and an elevation measurement device 2. The elevation measurement device includes a measurement object 15 which is measured by the height measurement device, a ranging sensor 16 for measuring the distance to a construction work plane and provided in a known relationship with the measurement object, a projection device for projecting elevation information, and a computation device 19. The computation device is constituted so as to compute the elevation information of a construction work plane on the basis of the height information of the measurement object measured by the height measurement device and the distance information measured by the ranging sensor, and the projection device is constituted so as to project the elevation information to the construction work plane.SELECTED DRAWING: Figure 1
