Zusammenfassung:Various embodiments of the present application set forth a computer-implemented method comprising aggregating positional signals that were received from device sensors, where each positional signal has an observed signal strength, identifying a subset of the positional signals, where each positional signal in the subset was received by a device sensor while the device sensor was located within the physical location, for each positional signal, generating, by an estimation device and based at least on a position of the device sensor, an approximate object height for an object located at the physical location, for each approximate object height, determining an expected signal strength for the positional signal corresponding to the approximate object height, generating a cost value that is based on a difference between the expected signal strength and the observed signal strength, and determining, by the estimation device and based on the cost values, an estimated object height.
