geotracker插件教程
今天给大家带来一款三 d 跟踪插件，传统跟踪一般只有平面跟踪，这款插件可以直接识别视频中的三维物体来实现跟踪，下面是使用教程，我们先在效果里找到这款插件，效果 拖拽到图层上，点击打开工具栏，然后我们要跟踪小孩手上这个盒子，那我们就选择立方体的跟踪器，现在移动跟踪器，让他贴合需要跟踪的物体， 然后在工具栏这里点击开始跟踪，把没有跟上的点手动微调一下，点击改进按钮，那我们就完成跟踪了。再给他创建一个空对象，可以看到空对象的路径已经跟踪好物体了，那我们就可以把素材给他放进去， 跟空对象链接复字集就完成了。这个插件还有很多类型的跟踪器，可以满足大部分三维素材跟踪， 甚至可以导入三维模型来作为跟踪器，或者跟其他插件进行联动，想玩的话赶紧来试试吧！

08:49查看AI文稿AI文稿hi， everyone in this tutorial， we are going to introduce you to geo tracker a 3d object tracking plugin for after effects you'll see how to install the plugin and learn the tracking pipeline we'll cover basic camera settings and talk about using tracking results next we'll see how geometry primitives and masks can help you and finally take a quick look at the essential appearance settings， geotracca allows you to reconstruct the 3d movement of an object in the footage this is called 3d tracking using the built in tools of after effects， third party plugins and other 3d software tracked objects can then be replaced enhanced used as particle emitters and so on let's see how it works to install go tracker visit our website download the package launch the installer and follow the instructions geotracca will appear in the effects and presets list we're going to track the car in this footage using its 3d model to get started add the footage to the timeline and apply geotracker the analysis of the footage will automatically begin you can always check its progress in the effect controls panel in the meantime， you can import a 3d model of the object you want to track geotracker supports fbx， obj and dae formats once the model is loaded you'll see its wireframe in the viewport it's an overlay which is only visible when the effect in this case， geotracker is selected when the analysis is finished you can start tracking the first step of tracking is setting up the initial position of the model aligning its wireframe with the object in the footage， you can do this by drag the points on the model to the corresponding points in the frame we call these little red dots pins you can remove a pin by clicking on it with the right mouse button note that pins are used only for positioning the model and don't affect tracking to understand what is going on here let's look at the results group when you drag a pin， you change the model's position and rotation in 3d space of course， it is possible to move the model by changing these parameters directly but with pins this process is much easier faster and more accurate once you have placed the model and analysis of the footage has finished you can start tracking first press the open toolbar button toolbar is a panel holding all tracking control buttons which are active only when go tracker is selected let's attach it to the stack on the right so you don't need to open it next time now press the track button as you can see in the beginning the model follows the object quite accurately， but at some point it slides off it's time to stop tracking and fix the model position let's do it on this frame and see what happens the new model position was recorded in a keyframe in the current frame and if you press u on a keyboard， you will see that all tracking data is stored in keyframes there are position and rotation keyframes and two manual keyframes this one is the initial keyframe and this one was just created the second keyframe fixes tracking only in its frame so the range between the keyframe still contains old tracking data as you can see the wireframe jumps when we switch between the manual keyframe and the frame just before it to update tracking data between keyframes place the playhead between them and press the refine button in the toolbar tracking has been updated and the movement of the model flows smoothly through the keyframes let's press play and see what happened to make the y frame overlay visible in the viewport while playing the video unfold the preview panel and enable the show overlays and layer controls the tracking is much better but the model still slides a little bit in the middle you can fix it with one more keyframe note that refine and tracking don't modify the manual keyframes they only change the tracking between these manual keyframes if you press the refine button right after aligning the model geotracco will retract the areas between the new keyframe and the nearest left and right manual keyframes let's review the result to make sure everything is all right now the movement of the model in this range became， smooth and accurate so we can jump to the last manual keyframe and track the remaining frames of the footage by the way you can move between keyframes using the keyframe navigation buttons in the toolbar as you can see the tracking results in this range are a little bit inaccurate again so let's fix it using keyframes and refine like we did before you can set as many keyframes as needed until the result is perfect， but we recommend keeping the number of keyframes as low as possible to avoid jerky movement when you're done you can press play and check the final result at first sight the tracking looks good enough but if you zoom in on the footage， you'll see that the model is a bit off it's happening because of the incorrect camera parameters let's check the camera group by default geotraca uses the active camera which isn't visible anywhere the easiest way to change the camera settings is to create a new camera layer and adjust its parameters you need to set the correct focal length in film size， which should be the same as the parameters of the real camera that was used to film the footage now this camera has become active because it's the topmost camera layer in the composition， but you can also see and select any camera layer in this list， there is also a custom camera option if you select it， you can set up the camera right in geotraca and the cool thing is that it allows automatic estimation of the focal length， while pinning see it gives us a number， which is pretty close to the focal length of the real camera let's now check and fix all other keyframes and click the refine all button to update the tracking we'll talk about cameras in detail in our future tutorials so let's go ahead once you're done with the tracking you can export the results as a null layer which can be used further in your pipeline for example， let's see you want to attach this speedometer to the car in the footage export group under object track press the export null button a null layer containing the tracking data will be created add the speedometer composition to the timeline and parent it to the null object adjust the speedometer by size and position and press play to learn more about this check out our exporting tutorial if you want to track a flat surface or something resembling a cube sphere or a cylinder you can use one of the built in primitives as a model for example， let's track this thermos with a cylinder adjust its radius align it and you're ready to track the object often you have to deal with occlusions in front of the object you want to track let's track the phone screen with a playing primitive as you can see overlapping fingers and pictures moving across the screen make tracking fail in this case， you can use a 2d mask to exclude the problematic areas create an adjustment layer and draw a mask on it in the layer menu select this layer so geotracker reads the mask from it now choose the source of the mask for drawn masks select the mask option and leave the channel parameter by alpha you are now ready to track the phone as you can see go tracker ignores the area with the pictures and the plane clearly follows the phone before we finish this tutorial let's take a quick look at the appearance group there are a lot of parameters， but the most important ones are the color and the opacity of the wireframe you can customize them to make the wireframe more distinguishable let's stop here if you want to learn more stay tuned and subscribe to our channel， we're going to release more tutorials with advanced tricks and techniques if you haven't already download go tracker and enjoy the fully functional free trial，
