手动方法 (The Manual Method)

I started with this pic of a Doctor Who novel I needed a straight image of. My picture is both crooked and receding in perspective, so I have my work cut out for me.

我首先从这张需要医生形象的照片开始。 我的照片在角度上既弯曲又在后退，所以我的工作适合我。

Press until you have the Polygonal Lasso tool. It looks like the selected tool above.

按直到拥有多边形套索工具。 看起来像上面的所选工具。

Draw points around your image by clicking the corners.

通过单击角在图像周围绘制点。

Press to copy your selection to a new layer.

按将您的选择复制到新图层。

Turn your Background layer off by clicking the .

通过单击关闭背景层。

At this point, I want to give myself a little more room to work with.

在这一点上，我想给自己更多的工作空间。

Press to bring up “Canvas Size.”

按下以显示“画布大小”。

I add an arbitrary amount of extra space around each side.

我在每侧周围添加了任意数量的额外空间。

Draw a horizontal rule by clicking on the and dragging into your image area.

通过单击并拖动到图像区域中来绘制水平尺。

Draw rules around your image. You want to create a rectangle that will become the new size and shape of your image. Err on the side of cutting into your image.

在图像周围绘制规则。 您要创建一个矩形，它将成为图像的新大小和形状。 错误切入您的形象。

Go to Edit > Transform > Distort while your layer is selected.

选择图层后，转到“编辑”>“变换”>“扭曲”。

Grab the points and stretch and warp your image until it more or less accurately fills the rules you drew. Notice I am not moving the points to fill the rules, but the image.

抓住点并拉伸和扭曲图像，直到它或多或少准确地满足您绘制的规则。 注意，我并不是在移动要填充规则的点，而是要移动图像 。

Without releasing your Distort Transformation, click the to draw more Horizonal Guides. Use them to check the straightness of lines in your image and adjust appropriately.

在不释放扭曲变形的情况下，单击以绘制更多水平向导。 用它们检查图像中线条的直线度并适当调整。

Press to release your Transformation.

按释放您的转换。

Press for the crop tool. Click and drag to create a square edged rectangle around your image. Don’t worry about cutting off some of the image.

按下获取裁剪工具。 单击并拖动以在图像周围创建一个正方形的矩形。 不必担心会剪切掉某些图像。

Press to finalize your crop. Your image is now straightened, in perspective, with clean edges around the sides.

按此完成定稿。 现在，在透视图中，您的图像被拉直了，两侧周围有干净的边缘。

第二种(更简单)的方法 (A Second (Easier) Method)

This is a method I would recommend not only for Photoshop Newbies, but for anyone that isn’t a crazy perfectionist that loves to do things manually.

我不仅向Photoshop新手推荐这种方法，而且还向不喜欢手工做事的疯狂完美主义者的任何人推荐这种方法。

Begin with your skewed image. Press for the crop tool.

从歪斜的图像开始。 按下获取裁剪工具。

Draw a rough outline around your skewed image.

在偏斜的图像周围绘制粗略的轮廓。

You should see a “Perspective” button in your Control Palette at the top of your screen. Turn it on if it is not. (If you don’t see it, you likely have a version of Photoshop that doesn’t support this)

您应该在屏幕顶部的控制面板中看到一个“透视”按钮。 如果不是，请打开它。 (如果看不到，则可能是不支持此功能的Photoshop版本)

Drag the corners of your crop to the skewed corners of your image. Your lines shouldn’t be squared off anymore.

将裁剪的角拖到图像的倾斜角。 您的线条不应该再分开了。

Press to release your crop.

按下以释放您的作物。

As you can see, this method is pretty much just as good, and faster. If you don’t want to worry about tweaking your image by hand, this is really the way to go.

如您所见，此方法几乎一样好，而且速度更快。 如果您不想担心手动调整图像，那确实是一种方法。
