Approximate size Age rating For all ages. See pcregistericp and pcregisterndt for more details about each algorithm. This example uses NDT, because it is typically more accurate, especially when considering rotations.

The pcregisterndt function returns the rigid transformation that aligns the moving point cloud with respect to the reference point cloud. By successively composing these transformations, each point cloud is transformed back to the reference frame of the first point cloud. Combine aligned scans: Once a new point cloud scan is registered and transformed back to the reference frame of the first point cloud, the point cloud can be merged with the first point cloud using pcmerge.

Start by taking two point clouds corresponding to nearby lidar scans. To speed up processing, and accumulate enough motion between scans, use every tenth scan. Prior to registration, process the point cloud so as to retain structures in the point cloud that are distinctive.

These pre-processing steps include the following:. In this example, the helperProcessPointCloud helper function accomplishes these steps. Display the raw and processed point clouds in top-view. Magenta points were removed during processing. These points correspond to the ground plane and ego vehicle.

After preprocessing the point clouds, register them using NDT. Visualize the alignment before and after registration. Notice that the point clouds are well-aligned after registration.

Even though the point clouds are closely aligned, the alignment is still not perfect. Now that the processing pipeline for a single pair of point clouds is well-understood, put this together in a loop over the entire sequence of recorded data.

The helperLidarMapBuilder class puts all this together. The updateMap method of the class takes in a new point cloud and goes through the steps detailed previously:. Processing the point cloud by removing the ground plane and ego vehicle, using the processPointCloud method. Estimating the rigid transformation required to merge the previous point cloud with the current point cloud. Additionally, the updateMap method also accepts an initial transformation estimate, which is used to initialize the registration.

A good initialization can significantly improve results of registration. Conversely, a poor initialization can adversely affect registration. Providing a good initialization can also improve the execution time of the algorithm. A common approach to providing an initial estimate for registration is to use a constant velocity assumption. Use the transformation from the previous iteration as the initial estimate. The updateDisplay method additionally creates and updates a 2-D top-view streaming point cloud display.

It's at the bottom of the window. Your video will begin downloading onto your computer. Open your video's location. Once your video finishes downloading, right-click it and then click Show in Folder in the resulting drop-down menu. This will cause a File Explorer Windows or Finder Mac window with your downloaded video to open, at which point you can double-click the video to play it in your computer's default video player.

On a Mac, you can hold down Ctrl while clicking the video to prompt the right-click menu to appear. Method 3. Install Documents by Readdle on your iPhone or iPad. Apple makes it sort of difficult to download files to your iPhone or iPad, so you'll use an app called Readdle.

Here's how to get it: Open the App Store. Tap Search at the bottom-right corner. Type readdle into the search bar at the top of the screen and tap Search. Follow the on-screen instructions. Open YouTube on your iPhone or iPad. It's the white icon with a red rectangle and white triangle inside.

Tap the magnifying glass at the top of the screen to search, or tap Library at the bottom-right corner to browse videos you've saved. Once you get to the video, it will start playing immediately. Tap Share. It's the icon with an arrow below the video's title. Several sharing icons will appear. Tap Copy link. It's the gray icon with two overlapping rectangles in the bottom row of icons. This copies the video's link to your clipboard.

Open the Documents app. It's the gray "D" icon with yellow and green accents. It should now occupy the last icon position on your home screen. Since it's your first time using the app, tap Continue when prompted, and then proceed through the screens until you reach the screen that says "Documents" at the top. Tap the blue compass icon. It's at the bottom-right corner of the "Documents" screen. This opens a web browser. You can do this by typing the URL into the "Go to this address" bar at the top of the screen and then tapping Go.

Tap and hold the "Enter Link" field. After a second or so, the "Select All" and "Paste" options will appear. Tap Paste. The YouTube video link you copied will appear in the blank. Tap the blue Download Now button.

Keepvid will locate the video and provide some download options below. Scroll down and tap Best Download. It's the blue button below the video's duration. The "Save File" screen will appear.

If you want a smaller file, you can tap the Download Other Formats button below instead and choose something else.

Rename the file optional and tap Done. This downloads the video to your iPhone or iPad. Once the video is downloaded, you'll be returned to the main Documents by Readdle screen. Add the Readdle folder to the Files app. If you add Readdle to your Files app it'll be easy for you to access your downloaded videos. Here's how: Open the Files app the blue folder on your home screen.

It may be buried in a folder. Tap Browse at the bottom. Tap Edit at the top-right corner. Slide the "Documents" switch to the On green position. Tap Done at the top-right corner. You can now use the Files app to access the videos you download with Documents by Readdle.
