1. A device for monitoring motion of objects of interest, comprising: a vehicle body; a flight mechanism for enabling the vehicle body to be directed along an aerial flight path; at least one camera; at least one device sensor including at least one of an orientation sensor or a motion sensor; at least one processor; and memory storing instructions that, when executed by the at least one processor, cause the device to: capture, as the device follows at least a portion of the aerial flight path during a period of time, image data using the at least one camera, the portion of the aerial flight path selected such that an area of interest is within a field of view of the at least one camera during the period of time; determine device motion data for the device, over the period of time, using data from the at least one device sensor; analyze, using the at least one processor, the image data to recognize instances of at least two types of objects of interest represented in the image data and corresponding to the area of interest, the at least two types of objects of interest including: at least one of a motorized vehicle or other motorized transportation and at least one of a pedestrian, animal, or-non-motorized transportation, each type of the at least two types of objects identified by a respective type classifier; determine a number of the instances of the at least two types of objects of interest represented in the image data, each of the number of instances having an associated confidence level for recognition based at least in part on the respective type classifier; determine, based at least in part on the number of instances and the respective type classifier, a respective path of motion for each of at least a subset of the instances over the period of time, the respective path of motion determined using the device motion data to account for motion effects in the image data resulting from movement of the device; and transmit information about the number of instances of the at least two types of objects of interest and the respective path of motion for the area of interest over the period of time.
