Abstract

The invention discloses an adaptive selection method for an adaptive region in real-time target matching and locating, and belongs to the technical field of computer image identification. The method comprises the steps of performing preprocessing and threshold segmentation on a real-time image; building a potential function by utilizing a spatial position relationship between a landmark and a target; by utilizing a local region stability index and a local region intensity index, performing first layer screening under the constraint of a spatial position potential function; performing non-maximum suppression on obtained candidate matching regions, and removing the regions with the relatively high overlapping degree; then performing correlation surface feature index screening and sorting; and finally selecting an optimal adaptive region through a potential function iterative strategy. Under the condition of insufficient matchable region quantity in target matching identifying and locating processes, the adaptive region which is abundant in information amount, is stable and reliable and is free of a repeat mode is selected in real time adaptively.
