Abstract

A measurement device (200) includes a measurement unit (202) which performs measurement by emitting electromagnetic waves and scanning an object with the electromagnetic waves, and a control unit (204) which controls the measurement unit (202). The measurement unit (202) is operable in a first scan mode in which the object is scanned in a first direction, or a second scan mode in which the object is scanned in a second direction different from the first direction. The control unit (204) determines a scan mode to be executed by the measurement unit (202).

First claim

The invention claimed is:

1. A measurement device mounted to a moving body, the measurement device comprising:
a measurement unit that measures an object by emitting electromagnetic waves and scanning the object with the electromagnetic waves,
a sending unit that sends, in a first sending mode or a second sending mode, data measured by the measurement unit, and
a control unit that determines, based on a moving state of the moving body, a sending mode to be executed by the sending unit,
wherein

the sending unit:
sends, in the first sending mode, measurement result in a predetermined range,
sends, in the second sending mode, measurement result in a part of the predetermined range, and
the control unit determines, based on speed of the moving body, the sending mode.

2. The measurement device according to claim 1 , wherein the second mode sends some measurement results within a predetermined range and does not send remaining measurement results.

3. A control apparatus mounted to a moving body, the control apparatus comprising:
a measurement unit that measures an object by emitting electromagnetic waves and scanning the object with the electromagnetic waves,
a sending unit that sends, in a first sending mode or a second sending mode, data measured by the measurement unit,
a control unit that determines, based on a moving state of the moving body, a sending mode to be executed by the sending unit, and
an information acquisition unit that acquires at least one of information related to features included in a map and traffic information requiring special attention,
wherein

the sending unit:
sends, in the first sending mode, measurement result in a predetermined range,
sends, in the second sending mode, measurement result in a part of the predetermined range, and
the control unit determines, based on at least one of the information acquired by the information acquisition unit and a current position of the moving body, the sending mode.

4. The control apparatus according to claim 3 , wherein the second mode sends some measurement results within a predetermined range and does not send remaining measurement results.

5. A measurement method executed by a computer mounted to a moving body, the measurement method comprising:
measuring an object by emitting electromagnetic waves and scanning the object with the electromagnetic waves,
sending, in a first sending mode or a second sending mode, measured data, and
determining, based on a moving state of the moving body, a sending mode to be executed,
wherein the computer:
sends, in the first sending mode, measurement result in a predetermined range,
sends, in the second sending mode, measurement result in a part of the predetermined range, and
determines, based on speed of the moving body, the sending mode.

6. The measurement method according to claim 5 , wherein the second mode sends some measurement results within a predetermined range and does not send remaining measurement results.

7. A control method executed by a computer mounted to a moving body, the control method comprising:
measuring an object by emitting electromagnetic waves and scanning the object with the electromagnetic waves,
sending, in a first sending mode or a second sending mode, measured data, and
determining, based on a moving state of the moving body, a sending mode to be executed, and
acquiring at least one of information related to features included in a map and traffic information requiring special attention,
wherein the computer:
sends, in the first sending mode, measurement result in a predetermined range,
sends, in the second sending mode, measurement result in a part of the predetermined range, and
determines, based on at least one of the information acquired and a current position of the moving body, the sending mode.

8. The control method according to claim 7 , wherein the second mode sends some measurement results within a predetermined range and does not send remaining measurement results.

9. A non-transitory storage medium storing a program causing a computer, mounted to a moving body, to execute as:
a measurement unit that measures an object by emitting electromagnetic waves and scanning the object with the electromagnetic waves,
a sending unit that sends, in a first sending mode or a second sending mode, data measured by the measurement unit, and
a control unit that determines, based on a moving state of the moving body, a sending mode to be executed by the sending unit,
wherein

the sending unit:
sends, in the first sending mode, measurement result in a predetermined range,
sends, in the second sending mode, measurement result in a part of the predetermined range, and
the control unit determines, based on speed of the moving body, the sending mode.

10. The non-transitory storage medium according to claim 9 , wherein the second mode sends some measurement results within a predetermined range and does not send remaining measurement results.

11. A non-transitory storage medium storing a program causing a computer, mounted to a moving body, to execute as:
a measurement unit that measures an object by emitting electromagnetic waves and scanning the object with the electromagnetic waves,
a sending unit that sends, in a first sending mode or a second sending mode, data measured by the measurement unit,
a control unit that determines, based on a moving state of the moving body, a sending mode to be executed by the sending unit, and
an information acquisition unit that acquires at least one of information related to features included in a map and traffic information requiring special attention,
wherein

the sending unit:
sends, in the first sending mode, measurement result in a predetermined range,
sends, in the second sending mode, measurement result in a part of the predetermined range, and
the control unit determines, based on at least one of the information acquired by the information acquisition unit and a current position of the moving body, the sending mode.

12. The non-transitory storage medium according to claim 11 , wherein the second mode sends some measurement results within a predetermined range and does not send remaining measurement results.
