Abstract
In a message receiver, a receipt timestamp is assigned according to a time of wirelessly receiving a message. Object data about an object is extracted from the message, including a timestamp adjustment for the object from a message sender. An estimated sender capture timestamp is assigned to the object by subtracting the timestamp adjustment and an estimated message transmission latency from the receipt timestamp; a receiver capture timestamp is assigned to receiver object data captured in the receiver. The sender object data and the receiver object data are combined according to the estimated sender capture timestamp and the receiver capture timestamp, thereby generating combined object data.
