Title:
VISUAL POSITIONING METHOD AND APPARATUS, DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/201990
Kind Code:
A1
Abstract:
The present application relates to the technical field of artificial intelligence, and discloses a visual positioning method and apparatus, a device, and a medium. The method comprises: performing feature splicing on an image coded feature and a text coded feature; performing feature fusion on the spliced coded features to obtain a first fused coded feature; respectively performing noise correction on the first fused coded feature and the text coded feature on the basis of a preset cross-attention mechanism to obtain a corrected fused feature and a corrected text coded feature, and performing feature fusion on the spliced coded feature and the corrected text coded feature to obtain a second fused coded feature; and correcting a preset frame feature by using a target coded feature determined on the basis of the corrected fused feature and the second fused coded feature to predict a regional position coordinate of the target visual object. Hence, according to the present application, image-text noise is corrected on the basis of the preset cross-attention mechanism, the impact of noise is weakened by reducing the attention on the noise part in the text, and anti-noise visual positioning is achieved.
