Abstract
A mobile image pickup device includes an imaging unit (20), an acceleration and angular velocity detecting unit, a processing unit that processes acceleration and angular velocity information which is detected by the acceleration and angular velocity detecting unit, a reaction wheel that rotates based on a command value which is calculated by the processing unit, and a housing (10) that accommodates the imaging unit (20), the acceleration and angular velocity detecting unit, the processing unit, and the reaction wheel therein.
Claims15
A mobile image pickup device comprising:
- an imaging unit;
- a processor configured to process acceleration and angular velocity information;
- three reaction wheels that rotate based on a command value which is calculated by the processor;
- a housing with a spherical shape that accommodates the imaging unit,
- the processor, and the three reaction wheels therein;
- and
- a plurality of fans that operate based on the command value and generate thrust for the housing,
- wherein the plurality of fans are disposed to be plane-symmetric with respect to three circles which are perpendicular to each other in the housing,
- wherein the three reaction wheels include rotation shafts which are perpendicular to each other, wherein the three reaction wheels generate a torque for causing the housing to rotate with rotation thereof, and the plurality of fans generate thrust for the housing by emitting air from an inside to an outside of the housing, and wherein a position of the imaging unit is controlled using the torque which is generated by the three reaction wheels and the thrust which is generated by the fans.
