| Hello everyone Why can't we have a "Clean car top view" in Matterport dollhouse-view ? Every time i scan a car, the dollhouse chops the car top. - I tried scanning top of car on multiple places (Hood, top, bonnet) see the BMW below link. - I also tried to raise the Monopod Hight. - I also tried to scan close to car sides. Q1: Do you have any tricks to overcome the choppy/broken 3D model ? Q2: What about scanning 4x4 cars & large trucks that is already higher than average, Advice? Example of broken car-models (click dollhouse view): BMW Lotus Camera: Insta360 ONE X (before you say anything.. The camera is perfect in scanning buildings and open spaces.. here is a sample of my work: Murdoc University Thanks  |

| I have done it successfullyใ Putting it on the roof is the correct way to do it but remember that their is a 1.5m bubble that your camera cannot scan. so you must raise your camera high enough to see the roof without being in the blind spot. This may mean raising the camera above roof height without putting it on the roof. This is my example. https://my.matterport.com/show/?m=EpqM45Kj9Ga Also be careful of reflected light off the vehicle. The glare is no different to the effect that sunlight makes outside. |

| In your examples, perhaps turn the lights off and scan once then again with the lights on. The vehicles are too reflective. In editing hide the spots with the lights off. | ||

| @Meidansha The model you've sent is BEAUTIFUL!! Naturally i have questions 1- Rooftop is scanned as "Floor2".. so we don't actually need to have a path (stairs) to lead to next floor right? you just scan floor1 (ground level + car interior) and then scan Roof top and mark it as floor2 , yeah? 2- You have scanned "around the camper" and "inside the camper" .. however, you managed to avoid a great challenge which is normally if i am inside and i click any sides of the camper, the camera will take me out of the van and into the "around the camper" area. How did you do that? did you "mark" the camper/van body as a "Window" so the user can not go through van walls ? 3- You said, scan my car with lights off and then again with lights on (i am assuming scanning same pints twice.. is that only for the top/car roof?) And why? what is the idea about scanning then hiding scans? is it to allow the capture app to collect more space details? One more: - I didn't understand about the 1.5M bubble and blind spot, can you explain? - When scanning above the car (shall i also lower the monopd Hight ?) Thanks a lot for sharing the Camper link, I really like it a lot! H. |

| Hello again @skyload300, I used the Matterport pro2 to make the scan so some of the methods may not work with your camera. I will answer your questions inline. 1- Rooftop is scanned as "Floor2".. so we don't actually need to have a path (stairs) to lead to next floor right? you just scan floor1 (ground level + car interior) and then scan Roof top and mark it as floor2 , yeah? โ"Floor 2" etc. is purely for your convenience of scanning and doesn't affect the end result (as I am told anyway). You do not need stairs to make the connection between floors so long as the camera can provide data that connects with other scans. In my case I climbed on the roof of the camper using a ladder, removed the ladder and scanned. I also used a tall tripod to scan around the outside first. 2- You have scanned "around the camper" and "inside the camper" .. however, you managed to avoid a great challenge which is normally if i am inside and i click any sides of the camper, the camera will take me out of the van and into the "around the camper" area. How did you do that? did you "mark" the camper/van body as a "Window" so the user can not go through van walls ? โThis is unfortunately impossible in your case. The windows of your cars can see outside so they connect with other points outside the vehicle. However if you scan inside a tight room like I did and you are careful about where you place your points in relation to the vehicle windows you MIGHT be lucky. I didn't make any markings on the camper walls or windows. 3- You said, scan my car with lights off and then again with lights on (i am assuming scanning same pints twice.. is that only for the top/car roof?) โI was refering to indoor scanning and the room lights. Cars reflect a lot of light. The Matterport Pro2 reads strong glare as a physical object and artifacts will be created in your dollhouse if you make a scan in a bright room. That is why I suggest scanning first in darker conditions and then rescanning just the main points in good viewing conditions. The first set of "dark scans" are for creating the creating the Doll-house the latter scans are for making the walkthrough. As it is uncomfortable for the visitor to shift between light and dark I recommend hiding the dark spots later in editing. The room I used was not a showroom but a repair pit and was pretty dark. Again your camera is different but this is how I achieved my results with a Pro2 Also the Pro 2 and the LEICA BLK have roughly a 1.5m radius where the readings of both the camera and the lidar (or infra-red sensor) are inaccurate so in the case of these cameras matterport's system ignores the readings making the point cloud data black. Any doll house data in that bubble will be ignored so putting the camera on top of the car won't work unless it is more than 1.5m away form whatever it is you want point cloud data of. Good luck and happy scanning! |

| @Meidansha Hmmm, That is useful information/tips. - How high was your camera lens from floor when you scanned the RV ? (higher than average eye level?) Please check this model that i found online, The cars looks AMAZING in both dollhouse and flat layout view. I am starting to feel that the issue is my Insta360 ONEX... unless you have another trick up your sleeve for me to try. Thanks a Million ! Hisham |

| @DanSmigrod hi Dan, Thanks for sharing the video, it is very interesting. I am mainly interested in Matterport. It's still driving me nuts, I just did 3 scans for a small Honda with different scan locations/hight/spacing from car body. And all rendered a broken choooy car in the Dollhouse/topview angles. While insta360 ONEX is really good in many other scenarios, I failed to scan car exteriors and yachts with it. Hmmm ! Photos attached below.   |

| @skyload300 scan the interior with the Insta360 , and change over to the Pro2 for exterior. With the Insta you are less likely to get broken artefacts inside the car like steering wheel or seats etc. For the roof just raise the camera and do extra scans, stay out of sunlight as the sunlight is cancer to the Pro2. If you are using the Insta for the roofs , do extra scan for it to fill it in. Sometimes reflective surfaces screws up the models, that is juts Matterport. Don't be too stressed with Dollhouse view its just a gimmick , and would say only 2% of viewers clicks on it. But I know its the only thing some MSP's knows how to sell Matterport. But lately I have been seeing a lot of stitching errors and broken artefacts in Matterport, also scan alignment issues , and processing taking hours were it was taking sometimes not even an hour. I have seen another company that only specialises in car 360 , it is the most amazing looking tours, and no its not Matterport. Sometimes the MSP's need to realise Matterport in not the only solution out there. Its like you going to the Dr and he only has a hammer to fix you , but he needs a saw , so he will try and fix you with the wrong tool. |

| @ThinkLab hello ThinkLab, thanks for the advice, insta360 has proven not good with cars, however great for stores/buildings. I don't see Dollhouse as a gimik since it's a main driver for end user's entertainment..this is their way in to spend more time on the client's model. I do not own a Pro2 yet, but I will keep your advice in mind (using both Pro2/Insta to complement each other). What is your website/insta ? |
