1. A method comprising: receiving, at a first time, from at least one depth sensor, and by a control system communicatively connected to the at least one depth sensor, a first point cloud representative of a first actor at a first location within an environment; associating, by the control system, sensor data received by the control system from at least one additional sensor with the first actor based on the sensor data from the at least one additional sensor being representative of the first location within the environment; identifying, by the control system, one or more attributes of the first actor based on the associated sensor data; determining, by the control system, that the first actor is undetectable in a second point cloud received by the control system from the at least one depth sensor at a second time later than the first time; receiving, by the control system, at a third time later than the second time, and from the at least one depth sensor, a third point cloud representative of a second actor at a second location within the environment; determining, by the control system, based on additional sensor data received by the control system from the at least one additional sensor, that the second actor has the one or more attributes; and based on determining, by the control system, (i) that the first actor is undetectable in the second point cloud and (ii) that the second actor has the one or more attributes, re-identifying the first actor as the second actor.
