Abstract: A layered convergence topology structure for a plurality of sensors is established based on a sensing range and a position relationship of at least one sensor from the sensors. A plurality of pieces of first sensed information, respectively captured through each sensor of the sensors, are divided into at least two first groups based on the layered convergence topology structure. Each piece of first sensed information in respective first group of the at least two first groups is converged to obtain at least two pieces of first converged information. The at least two pieces of first converged information are determined as at least two pieces of second sensed information for convergence to obtain second converged information. When a piece number of the second converged information is one, the second converged information is determined as target converged information.
