Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for displaying an information of a working face, which makes it possible that a worker executes a construction work, while viewing a ground condition of a surface of blow-coated concrete, in addition to secure safety by way of blow-coating concrete on the working face.SOLUTION: Firstly taking pictures of the area including a first working face which is an exposed surface of a ground of a cutting face exposed by means of blast drilling by using a digital camera, and creating information image data of the working face, which include a display information for showing a ground condition of the working face based on photographed image data. Meanwhile, blow-coating concrete on the first surface of the working face, and projecting a working face information image which is an image showing the working face information image data on the second surface of the working face which is this blow-coated concrete surface. Thereafter determining a construction information such as charging holes etc on a projected image, creating working face information update image data by adding a display information of the determined construction information to the working face information image data, and projecting the working face information update image data which is the image for showing the created the working face information update image data to the second surface of the working face.SELECTED DRAWING: Figure 1
