Systems described herein allow for placement and presentation of virtual objects using mobile devices with a single camera lens. A device receives, from a first mobile device, a target image captured from a camera and target image data collected contemporaneously with the target image. The target image data includes a geographic location, a direction heading, and a tilt. The device receives, from the first mobile device, a first virtual object definition that includes an object type, a size, and a mobile device orientation for presenting a first virtual object within a video feed. The device generates a simplified model of the target image, and stores the first virtual object definition associated with the target image data and the simplified model of the target image. The device uploads the first virtual object definition and the target image data, so the first virtual object is discoverable by a second mobile device.
