Abstract

The invention discloses an image positioning method and device, a storage medium and a program product. The method comprises the following steps that: determining at least one matching area matched with an image template from an obtained picture; according to the at least one matching area, determining a target area; according to a feature matching algorithm, extracting first feature information in the target area; according to a preset identification condition and the distribution feature of the first feature information in the target area, determining at least one effective area in the target area; and according to the distribution features of the feature information in at least one effective area, determining a result image. By use of the scheme, efficiency for identifying a specific type of pictures can be effectively improved, and accuracy for identifying the specific type of pictures can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method, device, storage medium and program product for positioning an image. Background technique [0002] At present, the traffic or parking lot generally locates and recognizes the license plate of the vehicle, so as to facilitate traffic management or payment management. The license plate location is mainly based on the color components to identify the license plate: the color space of the captured picture is converted from the RGB color model to the HSV color model, the blue component of the picture is extracted, the area with the blue component and exceeding the threshold is set as the foreground area, and the The other parts of the picture are used as the background area, and then the prior knowledge of the license plate is used in the foreground area to identify the license plate in the foreground area. If the identification card is identified by ...
