stable diffusion ControlNet使用介绍与进阶技巧

ControlNet是什么？固定构图、定义姿势、描绘轮廓、单凭线稿就能生成一张丰满精致的插画……它几乎无所不能。

有人把它称为AI绘画界的“革命性”突破，但在我看来，它不过是StableDiffusion迈向“工业化”的第一步。

生成信息

注：生成信息也可以读取到ControlNet，但无法直接一键应用。

你可以从最后这些字段中，查看这张图片用了几个ControlNet，权重、引导步数分别是多少。

AI二维码+艺术字+光影光效+创意Logo生成方法

艺术字实现介绍

在ps中制作一个白底黑字的图片

拉入到ControlNet

生成参数参考

stone, rock, coal,sand,from above,
high quality, highres, masterpiece, solid background
Negative prompt: (worst quality:2),(low quality:2),(normal quality:2),lowres,watermark,monochrome
Steps: 20, Sampler: Euler, Schedule type: Automatic, CFG scale: 7, Seed: 2109960192, Size: 960x540, Model hash: 038ba203d8, Model: 二次元：AbyssOrangeMix2_sfw, ControlNet 0: "Module: depth_midas, Model: control_v11f1p_sd15_depth [cfd03158], Weight: 1, Resize Mode: Crop and Resize, Low Vram: False, Processor Res: 512, Guidance Start: 0, Guidance End: 1, Pixel Perfect: True, Control Mode: Balanced, Hr Option: Both, Save Detected Map: True", Version: 1.9.4

使用不同的模型,logo，ControlNet预处理和提示词（不同材质）可以生成不同风格的图片

介绍图片融字实现

两个新模型：brightness（亮度模型） & illumination（明度模型）

修改ControlNet参数如下（这里用invert是交换黑白部分）

将文字添加在人物衣服上

例如这张图

Photo of a stunning country 22 year old woman, freckles, beauty spots, slightly curvy, flannel shirt open, winter hat, hard shadows, soft light, summer,full body,
Negative prompt: (deformed iris, deformed pupils, semi-realistic, cgi, 3d, render, sketch, cartoon, drawing, anime, mutated hands and fingers:1.4), (deformed, distorted, disfigured:1.3), poorly drawn, bad anatomy, wrong anatomy, extra limb, missing limb, floating limbs, disconnected limbs, mutation, mutated, ugly, disgusting, amputation

拉入photostop，将文字放到合适的位置

好了之后隐藏人物图层，导出文字，再拉入ControlNet

先再unit0放入人物图片，开启openpose

再到unit1放入文字图片，开启invert

生成效果（这里我关掉了unit0，不知道为啥带上图片会发黄）

二维码

首先准备一张二维码这里我以本文网址为例

unit0

unit1

生成效果
