Abstract

The embodiment of the invention provides an image acquisition method and device based on a target object. The method comprises the following steps: acquiring a plurality of image frames changing according to a time sequence by using a camera in a preset time period, and selecting a target area corresponding to a target object from each image frame; determining attribute information of each targetarea, wherein the attribute information is used for representing the imaging quality of the target object in the corresponding image frame; calculating the imaging difference of the target object in the image frame according to the attribute information, judging the imaging change trend of the target object according to the imaging difference, wherein the imaging change trend is used for representing whether the target object tends to be static or not in front of a camera; and acquiring an image of the target object in a preset time period when the imaging change trend of the target object reaches a preset condition by using a camera.

Description

technical field [0001] This specification relates to the field of computer technology, and in particular to an object-based image acquisition method and device. Background technique [0002] Image recognition is an important research topic in the field of computer vision and is widely used in industry. With the development and popularization of mobile devices, it has become the application development trend of image recognition technology in the future to achieve certain commercial applications (such as mobile payment) by running image recognition algorithms on terminal devices. In the implementation process of image recognition technology, in order to achieve a higher recognition rate, it is necessary to ensure that the collected images containing the target to be recognized have high quality, so how to quickly collect high-quality images has become a key issue in image recognition technology one. [0003] In the prior art, when collecting images of targets to be identifi...
