## Abstract

A measurement apparatus is to be mounted on a flying craft that flies in vicinity of the architectural structure and the measurement apparatus controls the flying craft to move to a measurement position indicated as a relative position with respect to a position of the flying craft and measures the architectural structure.

## Claims

### Claim 1

A measurement apparatus to be mounted on a flying craft that flies in vicinity of an architectural structure, the measurement apparatus controlling the flying craft to move to a measurement position indicated as a relative position with respect to a position of the flying craft and measuring the architectural structure.

### Claim 2

A measurement instruction apparatus to perform an observation of a position of an architectural structure and a position of a flying craft that flies in vicinity of the architectural structure and, based on the result of the observation, to provide a measurement apparatus on the flying craft an instruction indicating a measurement position where the measurement apparatus is to measure the architectural structure as a relative position with respect to the position of the flying craft.

### Claim 3 (depends on 1)

A measurement system comprising:
the measurement apparatus according to claim 1; and
the measurement instruction apparatus to perform an observation of a position of the architectural structure and a position of the flying craft and, based on a result of the observation, to provide to the measurement apparatus an instruction indicating the measurement position.

### Claim 4 (depends on 3)

The measurement system according to claim 3, wherein the measurement instruction apparatus is mounted on a stationary flying craft that is stationary at a position where the architectural structure and the flying craft are observable.

### Claim 5 (depends on 3)

The measurement system according to claim 3, wherein
the architectural structure includes a marker that is detectable by the measurement apparatus, and
the measurement apparatus detects the marker and controls the flying craft based on a position of the marker thereby causing the flying craft to move to the measurement position.

### Claim 6 (depends on 4)

The measurement system according to claim 4, wherein
the architectural structure includes a marker that is detectable by the measurement apparatus, and
the measurement apparatus detects the marker and controls the flying craft based on a position of the marker thereby causing the flying craft to move to the measurement position.

### Claim 7 (depends on 3)

The measurement system according to claim 3, wherein
the measurement apparatus controls the flying craft to fly on a flight plane at a predetermined distance with respect to the architectural structure, and
the measurement instruction apparatus provides an instruction to the measurement apparatus indicating the measurement position as the relative position on the flight plane with respect to the flying craft.

### Claim 8 (depends on 4)

The measurement system according to claim 4, wherein
the measurement apparatus controls the flying craft to fly on a flight plane at a predetermined distance with respect to the architectural structure, and
the measurement instruction apparatus provides to the measurement apparatus an instruction indicating the measurement position as the relative position on the flight plane with respect to the position of the flying craft.

### Claim 9 (depends on 5)

The measurement system according to claim 5, wherein
the measurement apparatus controls the flying craft to fly on a flight plane at a predetermined distance with respect to the architectural structure, and
the measurement instruction apparatus provides to the measurement apparatus an instruction indicating the measurement position as the relative position on the flight plane with respect to the position of the flying craft.

### Claim 10 (depends on 6)

The measurement system according to claim 6, wherein
the measurement apparatus controls the flying craft to fly on a flight plane at a predetermined distance with respect to the architectural structure, and
the measurement instruction apparatus provides to the measurement apparatus an instruction indicating the measurement position as the relative position on the flight plane with respect to the position of the flying craft.

### Claim 11

A non-transitory computer-readable recording medium storing a program for causing a computer to execute processing comprising:
performing an observation of a position of an architectural structure and a position of a flying craft;
providing, based on a result of the observation, an instruction indicating a measurement position where the architectural structure is to be measured as a relative position with respect to the position of the flying craft; and
measuring the architectural structure at the measurement position.
