Document Type and Number:
Japanese Patent JP2020201667
Kind Code:
A
Abstract:
To provide a drawing superimposition device with high convenience capable of easily and surely performing a construction error check of a civil engineering structure.SOLUTION: A drawing superimposition device 1 includes a drawing superimposition device main body 100 and a depth camera 200 connected to the drawing superimposition device main body 100 by wire or wirelessly. The depth camera 200 includes: one optical camera 210 that images a two-dimensional image in a real space; and a depth data generation unit 220 and an inertial measurement unit 230 that acquire position calculation information for detecting a focal position and a direction of the optical camera 210. The drawing superimposition device main body 100 includes: a drawing data storage unit 110 that stores drawing data; a position calculation unit 120 that calculates, based on a real space image, depth data, inertia information, and drawing data acquired from the depth camera 200, a current focal position and a direction; and a superposition display control unit 130 that superposes the drawing data on the real space image and outputs it to a display device 160.SELECTED DRAWING: Figure 3
