Kind Code:
A1
Abstract:
A method for updating an image template, a device, and a storage medium, the method for updating an image template comprising: collecting an image of a target object to obtain a target sample image of the target object (101); determining that the similarity between the target sample image of the target object and a first image template of the target object is within a first preset range (102); using the target sample image to pre-replace each image template of the target object so as to obtain at least one pre-replaced template set (103); calculating a uniformity parameter of each pre-replaced template set in the at least one pre-replaced template set (104); and if the uniformity parameter of the pre-replaced template set obtained after the target object has replaced a second image template is smaller than a preset uniformity numerical value, then using the target sample image as the image template of the target object and replacing the second image template (105). The described method ensures uniform distribution of image templates in a target object, and improves the accuracy and recognition rate of image recognition.
