Abstract

An apparatus for drawing an image on a development-view image of a structural object includes circuitry configured to display a first development-view image of the structural object captured at a first time, a first diagnosis target element image drawn for at least a part of a diagnosis target in the first development-view image, and a second development-view image of the structural object captured at a second time later than the first time superimposed one to another; receive a drawing of a second diagnosis target element image for at least a part of the diagnosis target in the second development-view image captured at the second time; and store first position information indicating a position of the first diagnosis target element image in the first development-view image and second position information indicating a position of the second diagnosis target element image in the second development-view image in association with each other.

First claim

What is claimed is:

1. An apparatus for drawing an image on a development-view image of a structural object, comprising:
circuitry configured to
display a first development-view image of the structural object captured at a first time, a user-drawn first diagnosis target element image drawn to indicate at least a part of a first diagnosis target at a first position within the first development-view image of the structural object, and a second development-view image of the structural object captured at a second time that is later than the first time, the first development-view image and the second development-view image being superimposed on one another;
receive a user-drawn second diagnosis target element image to indicate at least a part of a second diagnosis target at a second position within the second development-view image of the structural object captured at the second time, the first diagnosis target being a same diagnosis target as the second diagnosis target; and
store, in a memory, first position information indicating the first position of the first diagnosis target element image within the first development-view image in association with second position information indicating the second position of the second diagnosis target element image within the second development-view image.

2. The apparatus according to claim 1 , wherein the circuitry is further configured to
receive an instruction of change in display transmittance for displaying the second development-view image, and
change the display transmittance for displaying the second development-view image, in accordance with the received change instruction in display transmittance.

3. The apparatus according to claim 2 ,
wherein the circuitry is further configured to receive an instruction of change in a first display transmittance for displaying the first development-view image and the first diagnosis target element image and change in a second display transmittance for displaying the second development-view image, for inversely and proportionally changing the first display transmittance and the second display transmittance,
wherein the circuitry is further configured to change the first display transmittance for displaying the first development-view image and the first diagnosis target element image and the second display transmittance for displaying the second development-view image, in response to receiving the change instruction of the first display transmittance and the second display transmittance.

4. The apparatus according to claim 1 ,
wherein the circuitry is further configured to receive a selection of one of (1) a first mode for displaying the second development-view image, and (2) a second mode for displaying the first development-view image, the first diagnosis target element image, and the second development-view image being superimposed on one another,
wherein, in response to receiving selection of the second mode, the circuitry is further configured to display the first development-view image, the first diagnosis target element image, and the second development-view image superimposed on one another.

5. The apparatus according to claim 1 , wherein the circuitry is further configured to
display a diagnosis information input screen for receiving an input of diagnosis information including a diagnosis result of the first diagnosis target identified by the first diagnosis target element image and the second diagnosis target identified by the second diagnosis target element image,
receive an input of the diagnosis information via the diagnosis information input screen, and
store, in the memory, third position information indicating a position of a diagnosis region including a diagnosis target image indicating the second diagnosis target in the second development-view image in association with the received diagnosis information.

6. The apparatus according to claim 1 , wherein the first position information indicates coordinates of a start point and coordinates of an end point of the first diagnosis target element image, and the second position information indicates coordinates of a start point and coordinates of an end point of the second diagnosis target element image.

7. The apparatus according to claim 1 , wherein the structural object is a tunnel.

8. The apparatus of claim 1 , wherein the first diagnosis target element image is drawn by a first user at the first position on the first development-view image,
the second diagnosis target element image is drawn by a second user at the second position on the second development-view image when the first diagnosis target element image is being displayed, and
the circuitry is further configured to store the first position in association with the second position after the second diagnosis target image is drawn by the second user.

9. The diagnosis system comprising:
the apparatus according to claim 1 ; and
a diagnosis management server that associates the first position information and the second position information.

10. A method of assisting of drawing an image on a development-view image of a structural object, the method comprising;
displaying a first development-view image of the structural object captured at a first time, a user-drawn first diagnosis target element image drawn to indicate at least a part of a first diagnosis target at a first position within the first development-view image of the structural object, and a second development-view image of the structural object captured at a second time that is later than the first time, the first development-view image and the second development-view image being superimposed on one another;
receiving a user-drawn second diagnosis target element image to indicate at least a part of a second diagnosis target at a second position within the second development-view image of the structural object captured at the second time, the first diagnosis target being a same diagnosis target as the second diagnosis target; and
storing, in a memory, first position information indicating the first position of the first diagnosis target element image within the first development-view image in association with second position information indicating the second position of the second diagnosis target element image within the second development-view image.

11. A non-transitory computer readable storage medium storing one or more instructions that, when performed by one or more processors, cause the one or more processors to execute a method of assisting of drawing an image on a development-view image of a structural object, the method comprising:
displaying a first development-view image of the structural object captured at a first time, a user-drawn first diagnosis target element image drawn to indicate at least a part of a first diagnosis target at a first position within the first development-view image of the structural object, and a second development-view image of the structural object captured at a second time that is later than the first time, the first development-view image and the second development-view image being superimposed on one another;
receiving a user-drawn second diagnosis target element image to indicate at least a part of a second diagnosis target at a second position within the second development-view image of the structural object captured at the second time, the first diagnosis target being a same diagnosis target as the second diagnosis target; and
storing, in a memory, first position information indicating the first position of the first diagnosis target element image within the first development-view image in association with second position information indicating the second position of the second d
