[0002] Engineering construction is a special accounting subject for construction and installation companies to collect and account for engineering costs; engineering construction is the activity of new construction, expansion, and reconstruction of construction projects according to the requirements of the construction project design documents. The construction process requires the surveying and mapping of the outlines of the constructed buildings to ensure the quality of the construction; building outline surveying refers to the measurement and mapping of the various external structural outlines of the building to determine whether the actual outline of the building meets the requirements. The building outline is an important indicator for measuring the quality of the building, and is of great significance for planning, designing, and evaluating buildings. The existing building outline surveying cannot accurately map the building outline error in real time during the construction process, nor can it dynamically feedback the building outline error surveying results during the construction process, which reduces the quality of the construction.

[0003] The Chinese invention patent with the announcement number CN113670225B discloses a device and method for measuring the contour of the water tongue in the air of a water discharge structure and its turbulent boundary. The device and method adopt a method of setting a water tongue plane, and the water tongue upper edge, water tongue lower edge and multiple water tongue contour projection points are respectively set in the water tongue plane; the laser plane is set parallel to the water tongue plane; the laser scale panel is set in the laser plane; the laser instrument is set on the laser scale panel; the projection plane, the projection scale panel and the water tongue contour projection points are set in the projection plane. In this way, the precise measurement of the contour of the water tongue in the air of a water discharge structure is achieved. However, the above technical scheme cannot achieve the dynamic measurement of the difference characteristics between the real-time contour of the water tongue in the air of a water discharge structure and the standard water tongue contour.
