Abstract: Systems and methods are provided for acquiring images of objects using an imaging device and a controllable mirror. The controllable mirror can be controlled to change a field of view for the imaging device, including so as to acquire images of different locations, of different parts of an object, or with different degrees of zoom.

Abstract: A computer-implemented method for scanning a side of an object to identify a region of interest is provided. The method can include determining, using one or more computing devices, a distance between a side of an object and an imaging device, determining, using the one or more computing devices, a scanning pattern for an imaging device that includes a controllable mirror, based on the distance between the side of the object and the imaging device, moving a controllable mirror according to the scanning pattern to acquire, using the one or more computing device and the imaging device, a plurality of images of the side of the object, and identifying, using the one or more computing devices, the region of interest based on the plurality of images.

Abstract: Determining dimensions of an object can include determining a distance between the object and an imaging device, and an angle of an optical axis of the imaging device. One of more features of the object can be identified in an image of the object. The dimensions of the object can be determined based upon the distance, the angle, and the one or more identified features.
