Title:
FIXATION POINT ESTIMATION METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/021742
Kind Code:
A9
Abstract:
The present application provides a fixation point estimation method and a related device. According to the method, an electronic device can acquire an image by means of a camera, ensures to input a simple sample having an adaptive distance scale by means of adaptive zooming, and obtains face position information and eye position information in the acquired image when a face detection result meets a preset face condition. On the basis of a region of interest (ROI) pooling module in a fixation point estimation network model, the electronic device can process an ROI of a target image block using a corresponding preset feature map size to obtain a feature map. The target image block is obtained by cropping the acquired image. The target image block comprises at least one of a face image block, a left eye image block, and a right eye image block. Different types of image blocks respectively correspond to preset feature map sizes. The method can unify the size of the feature map by means of the ROI pooling module, thereby avoiding deformation of the target image block after scaling, and improving the accuracy of fixation point estimation.
