It's best to show meshes without texture. Every software can do texturing so the mesh difference is what matters.

Hi. I'm only just becoming familiar with photogrammetry, so I REALLY appreciate the time you took to produce this video review comparison. It was extremely enlightening. Regards Mark in the UK

Hi there, thanks for the comparison. The reason RC made a single 8k texture is because that is the default. To get the best texture, make a new unwrap using the unwrap tool using "fixed texel size" style with the texel size set to "optimal". Then texture again.

Thanks for the tip !

Most programs use the same algorithms, so you are more or less testing the default settings. But for noobs this is valuable information. I used Metascan until 2022, and then I changed to Zephyr. Results are pretty much the same. It's the input that defines the output via the settings (metashape has no holes in the roof, but fuses the planks, zephyr has hole in the roof but seperates the planks) . Drone shots are always challenging. Good sharpness and depth of focus are paramount. But so is lack of noise, with a small sensor camera that is always challenging. Good work, BTW.

A beautifully produced video. I’m keen to see future more in-depth videos on how to use the individual programs

Phantastic Review! Thank you for all your time and effort. Cheers Martin

This is exactly the video I needed. I'm wanting to try photogrammetry, and this is very helpful.

Thanks for such nice and fun to watch comparison :), cheers!

Thank you for the introduction to photogrammetry. Now I have a basic understanding thanks to your efforts. Nicely done sir!

Thank you for that laborious comparsion! I think it is difficult to compare them with "default" values. Some software closes, lets say, 10% holes of the mesh, while the other app clothes 80% of it at default. So, maybe you append a "part two" here with the best presets you found out.

very good comparsion, thanks for making this high quality video!

Very good explain and comparison ❤

Thank you! Great review and well done!

Great video. As I was waiting, I thought that it it would be really cool if, next time you compare software or other things, you could have each software's stats (time to generate the model in this case) over the video of the respective softwares instead of as columns from left to right. It would also allow you to update the data on screen making watchers more engaged.

For vertical infrastructure, bentley's Context Capture was amazing. I think they bought it from acute a few years back. Might be screwing up the names, been forever since I've used it but I was the most impressed with it for anything going vertical. But great comparisons. I'm only familiar with Meta and Reality Capture, Meshroom scared me when I started playing with it.

One important thing to understand… never ever use metashape with default preset buttons. Try to always use custom numbers for poly and tie points. Never generate the dense point cloud. I usually run 2- 5 million tie points on camera align step. Then you need to use the gradual selection masking to delete failed points in all of the categories like reconstruction uncertainty.. later generate the mesh only by using depth maps.. set the mesh density to custom and at least 10 million polys.. you can decimate it later. Have a good scan

Thank you for exclusive quality video

Great video for the newbies in the photogrammetry world! Thanks for the thoroughly comparison and keep the good job. i’m a civil engineer and usually work with lidar scans for field surveys of buildings. Can you tell if all the models that you make could be usable for measurements of element dimention and distances?. The lack of detail in the barn truss in meshroom model seems to be a negative point. Do you believe that using the doble of resolution could bring this elements into the model?. Thanks again for the great video 🎉.

Great comparison.

Great Work! I really like Metashape, and its predecessor, PhotoScan, I´v been using since back than. I think is very fast even for testing and there are some "hidden" features, as map transfer based on the original photos used (pretty cool). Now, seeing all the other options i can be sure that the Metashape fits better to me. Thank you

wonderful introduction！ Thanks

can you make a video tutorial for the shooting process only?

Nice comparaison 👌

Thank you for making this video, it is very informative. Once you come to the comparison of the four apps side-by-side, your focus is on the features. That many images aligned, so many triangles produced... But more important is how do you overall like the end result? It depends on the application of the model of course, but taking everything into account which package would you go with to model existing buildings, with a good, detailed, small-scale texture, to allow lighting to be added once the model has been made and imported in 3D design software? Thanks.

I just started the video and noticed that you were shooting at f1.7 which gives you a very shallow depth of field and makes it tough for the programs to recreate a sharp image. I would try f8 and raise your ISO so you keep at least 1/200 shutter speed. I think you will find great results.

I agree with you it's a very interesting job, but with reality capture you can get much better results.

Ok, the photos --> crappy high-poly mesh is an interesting step, but much more important is the crappy mesh --> usable mesh + texture. Can you do a review of level of automation and quality of this step for diff packages?

You need to open the 3d file generated by the "texturing" step, which also stores the UV information to load the textures. I used Blender to render the result, but any 3d software will do fine as long as you feed it the right file.

This is an interesting video but it's impossible to make a choice based only on you using each application with the default settings. It would be much more useful to see a comparison after you have got used to the software and used more optimal settings. It would also be very useful to know your PC specifications, especially CPU and memory, to get an idea of approximately how long processing might take on a different system. Would you consider redoing the processing with the same dataset? Thank you.

ty for the comparison. 27 4k (216 mpix) textures is only "double" from 4 x 8k textures.. yes.. they are so many either way

I loved the comparison, very complete. I just want to comment that I just saw that Reality Capture will ditch the PPI model and offer free versions for students/hobbyists and $1250 / year for companies making >$1M per year

Usually for serious tasks where I need quality, I choose Metashape. It collects sharp, accurate meshes. Sometimes I try to work in Reality Capture, but it often cannot glue an object into one part and splits it into several components, and gluing them together manually with dots is much more time-consuming. When comparing these two programs, I understand that Metashape is more geodetic software and of course the quality is more serious. Reality Capture began to lose in the last two years, although in some moments it is more convenient. But convenience does not equal quality. Despite the fact that I work in Unreal Engine and export my meshes to this engine, and of course RC exports it to the engine more conveniently, while in MS I have to tinker with dimensions and pivots. In general, choose what is convenient for you for a specific task.

Hi, thank you for this great comparison! Not directly related but to the process: instead of taking multiple single photos, how about taking a clip and splitting it into photos later. The resolution of each might be lower but the amount of information might be override this. I would be interested in hearing your thoughts

When the drone takes a photo, it embeds the geospatial info within the file: lat lon, camera data at time of image, etc. Stills extracted from video will lack the geo data required to be ingested by these photogrammetery apps.

@@02CanGT It isn't a requirement at all to have any image metadata, even camera intrinsics can be inferred from the images. Meshroom can take a video and use every n frames, it even has a motion blur filter that removes images that appear blurred. While having lots of images is generally a good thing, it's going to struggle with the lower resolution of a video. Better to have fewer high res images than a load of dross.

Jerome, thank you for the detailed, objective comparison. One question: Can you clarify which *versions* of the software were used? For example, 3DF v7+ is completely different than prior versions, making this a very important detail. Thank you!

Thank you ! I do not own any suitable Apple device (phone or iPad), so I won't be able to compare the results. From what I understand of this app, it makes use of the new lidar on the latest versions of the IPhone, in order to speed up the results. It mostly works in close proximity, so for a building like the one I scanned in the video, it might be a bit cumbersome. For the dataset, I'll see if I can find it and post a link to it. I'd be interested in seeing what you can achieve by tweaking the parameters ! Keep in mind that I did not completely cover all the parts of the building, and some photos are grossly underexposed/bad.

Just a tip for the cinematic shots at the beginnig. Buy a ND Filter Set for the Mavic so you can use the 180° rule for your shutter speed. The shots look really "jittered" because you used a really high shutterspeed.

Drone mapping and 3d modeling are different things. Generally in mapping, the accuracy of the end result matters the most. You should be able to measure distances on the final map with very high accuracy. That's why RTK drones are used. Technical info: GPS singal has some inanncuracies, especailly when measuring heights. An RTK station measures the GPS signal at the same time as your drone flies. Since the station is stationary, you can "fix" all the measurements to be stable. Then you apply all those corrections to the drone's GPS position. Therefore you get much more accurate results.

Really ought to upload in 60fps, alot of the panning shots are hard to follow due to the stutters. 5:00 and 6:00 example

You should compare the point cloud not the mesh, since mesh can be done with many different parameters from the original point cloud

i think the comparison would be more precise if u had single rendern engine for all 4 models, furthemore there are a lot of settings that can be tweaked during the process of aligning photos and camera positions, in all programs that can misslead the final result great video tho)

You can, but it won't be easy. It will take A LOT of time since the software will have to position the "frame" somewhere in space. You see, one good thing with photos taken from a drone, is that they have embedded their geolocation (position, height, angle of camera e.t.c.) Also if the given video was shoot in a fast pace (and therefore blur is present on the frames) it will also make it much harder for the software to process.

It took way too long for what I wanted to do, but it does look smoother and makes it easier to compare the different meshes.

Thank you for the testing, but the verbal conclusions had almost zero value. Reality Capture is the king of all as seen from the Video Captures. Spitting out numbers does not speak of quality, of which RC is the absolute beast. Dedicated talk on edge quality, geometry quality (straight edges when there) is the most important thing, as well as texture tone quality (the way the software outputs colour and shadows/highlights). Leaving out edge and surface quality is like talking only to people that will retopologize the entire model, which is 1% of the users, at best.

A point barely mentioned, GPU usage. Nvidia support doesn't help if your workhorse PC has an AMD GPU.
