1. A method for depth and color camera image synchronization, the method comprising: obtaining a plurality of input images comprising a first image type and a second image type different from the first image type, wherein an image type is either a depth camera image type or color camera image type, wherein each image type is unsynchronized with respect to images of other types, and wherein each of the plurality of input images are without identification of an input image's actual creation time; selecting, from input images of the first image type, a target image; selecting, from input images of the second image type, a comparison image; determining whether the comparison image is compatible for synchronization with the target image; in response to a determination that the comparison image is compatible for synchronization with the target image, identifying the target image and the comparison image as a synchronized image pair; and processing the synchronized image pair together for use in an augmented reality output.
