利用Midjourney生成高质量高达图片，这些Ai提示词模板必须掌握

之前看到有网友使用AI绘图生成了一系列高达机器人的图片，看到大家都很感兴趣，就让我和大家分享一下如何生成这些漂亮的高达图片吧。

我使用的是Midjourney来生成高达图片。由于该工具表示“有大量的来自中国的流量不断注册一次性帐户（throwaway accounts）来生成免费图片”，因此从上个月开始，Midjourney已经停止了免费试用功能。想要体验的同学只能想办法搞张美国哦信用卡购买了会员了，这样才可以使用Midjourney生成心爱的高达图片了。现在让我们先看看如何生成高达图片吧。

如何生成图片：完成注册后进入Midjourney的Discord，在左侧导航栏找到“GENERAL IMAGE GEN”，选择任意一个general房间（见①），然后在对话框中输入/imagine prompt，再在框内输入你想要的提示词（见②）。

AI 生成高达图片的提示词 AI 生成高达图片的提示词 –niji 5

这次我们使用Midjoureney最近推出的“niji”模型。与v1至v5模型不同之处在于，niji是专门训练生成高质动漫风格图像的模型。要生成像编辑这样的高达动漫风格图片，一定要加入“-niji 5”的提示词。

本次我们以渣古作为示范：

下面的U/V 1-4分别对应上面的图片，U代表放大，按下将会生成相应位置的大图；V代表变化，按下将会根据选择图片的风格额外生成4张图片。

这种风格的新渣古很特别吧？

使用命令 “-niji 5” 可以生成动漫风格的图片，而前面的 “-ar 1:1” 则是生成图片的比例。例如小编上面的 “1:1” 就代表会生成一张正方形 1:1 的图片，如果使用 “-ar 16:9″，则会生成横向宽度为16，高度为9的图片。如果想要生成纵向照片，则需要改成”-ar 9:16″。不同比例的照片都有不同的效果，建议大家多尝试不同比例。

在命令行的末尾输入 “-ar” 后面跟着数字 “4:6″，就可以得到直立的图片。

同理，输入6:4，就可以得到一张横向的图片。

我还尝试了其他几组提示，并生成了下面这些图片。

左上方的那张高达图片风格看着不错，所以按下了V1键，让Midjourney参考这张图片再生成4张类似风格的图片。Midjourney 可以根据编辑选择的图片再生成 4 张风格相似的图片。

下面十几种不同风格的提示词：
