Abstract

The invention discloses a method and a device for searching a target image. The method comprises the following steps: collecting a plurality of feature points in a target subimage; converting the target image into a one-dimensional array from a two-dimensional pixel matrix, and adjusting relative offsets among the feature points corresponding to the conversion manner; searching the one-dimensional array by using the adjusted relative offsets. On one hand, the feature points are adopted for searching, thus the defects of a method for contrasting pixels frame by frame in a correlation technique can be avoided, and on the other hand, the one-dimensional array corresponding to the feature points is adopted, thus the calculated quantity in the searching can be reduced further, and the search efficiency is ensured.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a target image search method and device. Background technique [0002] At present, with the continuous deepening of informatization, people have obtained a large number of digital target images. How to determine whether a target sub-image exists in a target image has become an important task in the field of software automation testing. Furthermore, how to count the number of the target sub-image in the target image, and how to determine the coordinate position of the target sub-image in the target image are tasks to be solved in the field of software automation testing. For example, when the embedded system UI performs a control (icon) detection task, the embedded system UI is the target image, and the control (icon) is the target sub-image, and the detection task is to find all controls (icons) in the embedded system UI. ), count its quantity and determine its coordinate positi...
