AI 扩图是什么

AI 扩图是把一张图片向画面之外延展,由模型凭空生成与原图衔接的背景和场景,也叫智能外扩或 outpainting。它不是把原图拉伸或裁切,而是预测边框以外应该出现的像素,让画面自然变宽或变高。常用来把竖构图扩成横幅,或补足空白以适配新的画面比例。

AI 扩图能做什么

  • 智能外扩,延续原图的场景与光影
  • 去裁切,找回更宽或更高的构图
  • 一键改比例,不拉伸也不变形
  • 生成式填充主体周围的空白画布
  • 上下左右任意方向定向扩展
  • 文字提示引导新增区域的内容

AI 扩图适合谁用

01

社交与广告改尺寸

把同一张图适配方形、竖版、横版,满足各平台的配图要求。

02

电商商品图

在商品周围补出干净背景,凑齐主图和详情页所需的比例。

03

壁纸与印刷

把照片扩展到手机、桌面或海报的满屏尺寸。

04

摄影与修图

补救过紧的裁切,为文字、logo 或留白重新腾出空间。

AI 扩图的原理

上传图片后向外拖动画布或选定目标比例,标出新增的空白区域。扩散模型读取原有像素,再结合可选的文字描述,把周围区域补画出来,让光线、纹理和透视自然延续。原图保持不变,只生成新增的边框部分,接缝不理想还能反复重新生成。
