A server receives video data and location data from mobile devices. Each mobile device records a video of a target. The location data identifies a position of the corresponding mobile device relative to the target and a distance between the corresponding mobile device to the target. The location data is associated with a corresponding video frame from the video data. The server identifies video frames from the video data captured from the mobile devices. The server scales parts of the identified video frames based on the position and distance of the corresponding mobile devices to the target. The server extracts the scaled parts of the identified video frames and generates a three-dimensional model of the target based on the extracted scaled parts of the identified video frames from the plurality of mobile devices.
