A Multi‐Person Selfie System via Augmented Reality

Abstract

Figure 1: The process of taking a group photo of two persons without asking for the help from others. We assume at first a female is holding the camera to take a picture of a male. (a) The starting status of capturing the male. Note that toggle button at the lower right corner indicates the status in which we need to wait for the system to turn the detected male into a virtual marker. (b) The ending status of capturing the male. Also note at the same corner the toggle button's status has been changed, indicating the completion of the virtual marker construction, and the readiness for capturing the second person, i.e., the female. Also note that the operation aid tool has been enabled (by clicking on the middle near the left border) so that it can be used to guide the male to take a photo with a similar configuration where the female took the first picture. Here a configuration means the orientation and distance of the camera, with respect to the male when the first picture was taken. (c) the male is holding the camera, and how its configuration differs from the original one is shown on the operation aid tool. (d) The female walks in while the male can keep on adjusting the configuration. (e) Once the male is satisfied with relative positions of the two persons, under the hint of the operation aid tool that the configuration is acceptable, he can take the second picture. (f), the final result of our system. Notice that the smaller images appear near the lower right part of (a)∼(e) show the real scenes observed from the camera.
