摘要:
A method for fabricating an imaging system, the method comprising providing a flexible substrate (200), a first layer (220) comprising a plurality of microlenses (232) and a second layer (240) comprising a plurality of image sensors (242). The method further comprises stacking the first and the second layer (220; 240) onto the flexible substrate (200) by attaching the plurality of image sensors (242) to the flexible substrate, such that each of the plurality of microlenses (232) and image sensors (242) are aligned to form a plurality of optical channels (300) , each optical channel comprising at least one microlens and at least one associated image sensor, and mechanically separating the optical channels (300) such that the separated optical channels remain attached to the flexible substrate (200) to form a mechanically flexible imaging system.
摘要:
The present invention concerns a vertical take-off and landing aerial vehicle flying thanks to a propulsion system (e.g. one or more propellers) that generates an upward force (lift) to counter gravity. The present invention proposes a vertical take-off and landing aerial vehicle comprising an inner frame (312), a gimbal system (301) and an outer frame (304), said inner frame comprising a propulsion system (101,102) and a control system, said propulsion system being able to generate a lift force, said control system being able to control the orientation of the inner frame, said gimbal system connecting the inner frame to the outer frame with at least two rotation axis allowing rotation freedom between the outer frame to rotate independently from the inner frame.
摘要:
A new method for the estimation of ego-motion (the direction and amplitude of the velocity) of a mobile device comprising optic-flow and inertial sensors (hereinafter the apparatus). The velocity is expressed in the apparatus's reference frame, which is moving with the apparatus. The method relies on short-term inertial navigation and the direction of the translational optic-flow in order to estimate ego-motion, defined as the velocity estimate (that describes the speed amplitude and the direction of motion). A key characteristic of the invention is the use of optic-flow without the need for any kind of feature tracking. Moreover, the algorithm uses the direction of the optic-flow and does not need the norm, thanks to the fact that the scale of the velocity is solved by the use of inertial navigation and changes in direction of the apparatus.
