A camera module device includes: a base plate; one or more cameras fixed to and disposed on one surface of the base plate; a plurality of movable cameras movably disposed on the one surface of the base plate and configured to move individually or collectively; a driving gear disposed on the base plate; and a plurality of sub-gears engaged with the driving gear, wherein positions of the plurality of sub-gears are configured to change to selectively transfer power to one or more of the plurality of movable cameras.

An example method for training a machine learning model is provided. The method includes receiving training data collected by a three-dimensional (3D) imager, the training data comprising a plurality of training sets. The method further includes generating, using the training data, a machine learning model from which a disparity map can be inferred from a pair of images that capture a scene where a light pattern is projected onto an object.

Disclosed are a camera module and an electronic device. The camera module comprises at least two cameras. Two cameras of the at least two cameras are disposed in parallel; incident optical axes of the two cameras are parallel to each other; each camera includes a reflecting element, an optical lens assembly and a photosensitive element; and reflecting optical axes of the two cameras are consistent or parallel to each other. The incident light is reflected by the reflecting element and passes through the optical lens assembly and is then imaged on the photosensitive element.

A camera, including: two imaging systems each comprising a different optical path corresponding to a different viewing angle of an object; one or more illumination sources; a mask disposed with multiple pairs of apertures, wherein each aperture of each aperture pair corresponds to a different one of the imaging systems; at least one detector configured to acquire multiple image pairs of the object from the two imaging systems via the multiple pairs of apertures; and a processor configured to produce from the multiple acquired image pairs a multi-layer three dimensional reconstruction of the object.

Unmanned aerial vehicles (UAVs) with stereoscopic imaging, and associated systems and methods are disclosed herein. A representative system includes a support structure oriented relative to a vehicle roll axis, pitch axis, and yaw axis. The system further includes multiple propellers carried by the support structure, and first and second stereo imaging devices, also carried by the support structure. The first stereo imaging device has a first field of view, the second stereo imaging device has a second field of view, and at least one of the multiple propellers is positioned forward of and between the first and second stereo imaging devices. The at least one propeller has a rotation disc that does not overlap with the first and second fields of view. In representative configurations the fields of view also do not overlap with other (e.g., any other) structures of the UAV.
