Abstract

An object of the present invention is to provide a guidance system and the like which are capable of showing an object from a point of view of an operator in an accurate manner when displaying the object on a display portion. A guidance system includes: a survey apparatus that surveys an object from a point of view that differs from a point of view of a user; and a display portion that displays the object from the point of view of the user, wherein the survey apparatus is configured to perform ranging by irradiating the object with ranging light and receiving reflected ranging light from the object, and survey information of the object having been surveyed by the survey apparatus is changed to the point of view of the user and displayed on the display portion.

Claims (28)

1. A guidance system comprising:

a survey apparatus that surveys an object from a point of view that differs from a point of view of a user; and

a display portion that displays the object from the point of view of the user,

wherein the guidance system is configured to generate shape information of the object by irradiating at least only one of the object and a periphery thereof with ranging light of the survey apparatus and receiving reflected ranging light from the object, and is capable of acquiring three-dimensional information of the object by selecting and executing an irradiation method of the ranging light that is suitable for the generated shape information, and wherein

the survey apparatus is configured to perform ranging by irradiating the object with ranging light and receiving reflected ranging light from the object, and

survey information of the object having been surveyed by the survey apparatus is changed to the point of view of the user and displayed on the display portion.

2. The guidance system according to claim 1 comprising:

a survey apparatus-side imaging apparatus that images the object from a survey point of view of the survey apparatus; and

a user-side imaging apparatus that images the object from the point of view of the user, wherein the survey information of the survey apparatus is changed to the point of view of the user based on information on a relative positional attitude between the survey apparatus-side imaging apparatus and the user-side imaging apparatus and displayed on the display portion.

3. The guidance system according to claim 2 , wherein

the guidance system acquires information on a target position to which the object is to be moved and

displays difference information between present position information and the target position information on the display portion in the point of view of the user.

4. The guidance system according to claim 3 , wherein

the guidance system acquires information on a target position to which the object is to be moved and

displays difference information between present position information and the target position information on the display portion in the point of view of the user.

5. The guidance system according to claim 1 , wherein

the guidance system acquires information on a target position to which the object is to be moved and

displays difference information between present position information and the target position information on the display portion in the point of view of the user.

6. A control method of a guidance system including a survey apparatus that surveys an object from a point of view that differs from a point of view of a user and a display portion that displays the object from the point of view of the user,

the control method of the guidance system comprising:

the guidance system generating shape information of the object by irradiating at least only one of the object and a periphery thereof with ranging light of the survey apparatus and receiving reflected ranging light from the object, and acquiring three-dimensional information of the object by selecting and executing an irradiation method of ranging light that is suitable for the generated shape information;

the survey apparatus performing ranging by irradiating the object with ranging light and receiving reflected ranging light from the object; and

changing survey information of the object having been surveyed by the survey apparatus to the point of view of the user and displaying the survey information on the display portion.

7. A non-transitory computer readable storage medium comprising a control program of a guidance system including a survey apparatus that surveys an object from a point of view that differs from a point of view of a user and a display portion that displays the object from the point of view of the user,

the control program causing the guidance system to execute functions of:

the guidance system generating shape information of the object by irradiating at least only one of the object and a periphery thereof with ranging light of the survey apparatus and receiving reflected ranging light from the object, and acquiring three-dimensional information of the object by selecting and executing an irradiation method of the ranging light that is suitable for the generated shape information;

the survey apparatus performing ranging by irradiating the object with ranging light and receiving reflected ranging light from the object; and

changing survey information of the object having been surveyed by the survey apparatus to the point of view of the user and displaying the survey information on the display portion.
