Great video, thank you. I’m not a surveyor- but I’ve been experimenting with an iPad Pro and point clouds / scans for architectural visualisation etc. I understand why you skipped the scale step, but I wondered how the data would compare if you had scaled. The data sets could be useful if used together perhaps? Not that I have a total station, or need one! I have been using 3D Scanner App and Polycam, and also SiteScape, which only records point clouds but (without using your rigorous testing methods) seems more accurate somehow. Subscribed 👍

iPhone: US$ 1.100,00 Professional Equipment: US$ 50.000,00 - US$ 200.000,00. The iPhone has a 0,5% margin of error + rendered texture and colored the surface accordingly. That is IMPRESSIVE. Conclusion: The iPhone LiDAR is not meant to be used in SOME professional setups. But it’s superb for everyday use for 99,99% of people and SOME professional uses: When the 0,5% margin will not like kill someone, for example. Great job Apple.

Hi Rami , I've been studying your iphone Lidar videos and I've decided to trial the Iphone as a method of detail surveying on residential house lots. Typically , here in sub tropical Brisbane ( Queensland , Australia) , I am dealing with lots of vegetation , trees , scrubs etc and slopes of 2 to 4 metres across a 25m x 40 m site. My method will be create controlled ground targets in good locations for GNSS pick up with my GPS and then Lidar scan the yard up to the fence line ., including the house , any sheds , tree trunks etc. Then I'll use Poly Cam on the iphone & Cloud Compare to register the point cloud , then import it into Autocad Civil 3D . Do you have any recommendations on the processing software or method ? I'll be using an iphone 13 with a gimble for stability. Looking forward to more research on scanning technology , as it impacts on surveying . Have you looked at generating ground contours from the Lidar scan ?

The phone has to keep track of where it is, as it’s performing LIDAR. So as you are walking taking shots with it, it must be using GPS to track where the phone is, thus also the locations in the LIDAR surface are dependent on the accuracy of the GPS??
@merseyviking
3 жыл бұрын
It's almost certainly not using GPS, instead it'll use a combination of sensor fusion (combining the accelerometer, gyroscope, and compass data to perform inertial tracking) coupled with SLAM - Simultaneous Location and Mapping where it uses the data gathered in the previous few frames to align the data captured in the current frame. This is the reason for the fairly linear error in the northing (the long axis), because inertial tracking will always drift over time. GPS can only be relied on to within 10 metres or so, and can vary wildly over only a few readings.

Awesome content! Thanks for doing this. So, I’m no surveyor so please correct me if I’m wrong. But isn’t this margin of error reasonable compared to the ability to place the center of the stake at each 10 foot increment, and then the additional error of trying to find the center of the stake in the point cloud? It just seems like a more clean testing environment would account for the relatively low range of error here. Each stake should have to be leveled to account for error there as well. Like, it seems clear it’s losing some accuracy over distance still. But now that this is proving to be possibly useful in the field, it would be good to find a way to get extra accuracy in the testing.

It didn't work well because I didn't have a good feature point detector and lidars were all kind of expensive. But this seems promising, and I'm pretty sure the drift can be fixed to an acceptable level if I sprinkle some registration marks all over the place for the phone to pick up and then locate them with a transit and tape.

Sorry I don't have the sensor details, but with the airplane data I can see the skeleton of the steel power poles along with the wires running between with very little error...or so it seems. With the iPhone the poles in the ground look like they were covered with a sheet and lack all levels of detail. With that much signal imprecision, how can you assume the highest point represents the top surface of the posts?

Thanks for the video. The errors you're getting for the iPhone lldar is almost entirely caused by the relatively low grade IMU (Inertial Measurement Unit or electronic gyroscope), rather than the laser (which is practically the same for the iPhone and the total station). That is why you got much better results for the curb in your last video, than in this case where you had to traverse that 200 foot distance. My guess (hope?) is that Apple will put better IMUs in future phones as the technology improves and consumers demand.
