It is basically making an image file that is a solid color that has the same exact dimensions as the images you are using. That's the purpose of using an image from the photoset.
I am completely confused how Metashape knows to choose the green color -versus- any other color on the screen? Nothing about the "background.jpg" mask indicates that it should focus on that area, that color, etc. Can you help clarify, what specifically is instructing Metashape to extract the greens in the background? For example, Photoshop has a "based on top/bottom left/right corner" color for cropping; could Metashape be using a logic along these lines where it searches for colors (within the tolerance) based on the color present in the top left/right of the screen, assuming that to be a "background" color? Or does it take the largest group of similar colors? Or something else? Thank you :)
I totally agree. I wish Agisoft were more transparent about this. Based on my experience, it seems as if Metashape is selecting the largest group of similar colors and that's why it can work with different color backgrounds. But to be honest, I'm not 100% sure. This might be a great question for the Agisoft discussion boards.
To capture the other side, flip the shoe over, and then capture the other side. Run the other side as a separate chunk. Then use a marker based alignment to align the two chunks. I have another video that shows how to do a marker based alignment.
Hello Alex, Thank you very much for your tutorial. When I select the folder where the background image is located an error "can't open file: The system cannot find the file specified (2)" show up. Do you have any suggestions to solve this issue, please?
I've had issues like this in the past. Make sure that your file's name matches the file name that you designate in the import masks dialogue. That might be it.
I would suggest that after doing masks, rerunning alignment using masks on key points. You should see that on the alignment dialogue as a check/uncheck option.
Hello Alex, thank you very much for your video. I am new to the acquisition of small objects and I am having some troubles with the acquisition using the turntable. The pics are great, metashape is able to align them but locate all them in the same position. Can you give me some tips about the setting?
Could you describe what you're seeing looks like and the whole setup? It really does depend. For example are you using a monochrome background or does the turntable have any distinctive marks?
Also, using a marker palette will help (alexelvisbadillo.weebly.com/gvals-resources.html). Go to that link and download them free. You will have to have it printed at a place like Staples or Office Depot at scale, but if you are planning on doing turn-table photogrammetry, it's worth it!
@@alexelvisbadillo Alex thank you for your quick reply. I think the problem was the background, as after changing it I have started to have good results!
@@alexelvisbadillo Thank you again, as soon as I can go to the office I will print it. In the meanwhile, I placed a coloured sheet which could help the software!
Hello Alex, Thank you very much for the video. I am completely new to Metashape Pro, specially when using it with a turntable. My first question is: do you need to mark the turntable ? the second question is, can you use the mask tool available in Metashape pro?
To your first question - there are many approaches to turntable photogrammetry. If you don't have a marker palette with the auto-registration markers like in this video, it is good to make the turntable have unique patterns on its surface and to place a scale bar in the scene. To the second question - this video is showing how to use the internal tools in Agisoft, only the background file is developed in MS Paint. Other masking methods can be done in Agisoft. Explore masking methods using the model. This uses the 3D mesh that you create to mask the images. This can be useful in some cases. And of course you can also manually mask images by opening the images in Agisoft and then using the selection tool or magic wand tool. After making the selection just hit CTRL+SHIFT+A.
Double check the spelling for the "background.jpg" file and make sure it matches in the masking tool. Also, ensure that you are choosing the folder that would contain the background file.
@@alexelvisbadillo oh okay it worked thanks😊. I have one more question please, what i do 1st is align photos then mask the unesccary, then align again?
so jus just replaced the file with solid white color? I don't get it what kind of information it will contain?
It is basically making an image file that is a solid color that has the same exact dimensions as the images you are using. That's the purpose of using an image from the photoset.
If this doesn't work for you you may want to try using an empty scene image like I do in this video here. ua-cam.com/video/LzN1w6BlbZE/v-deo.html
@@alexelvisbadillo cheers!
why its does not automatically mask for me? although my background is plane white

Hey man one question please, so after aligning first and then doing masks, after that process i need to re align again?
I would suggest that after doing masks, rerunning alignment using masks on key points. You should see that on the alignment dialogue as a check/uncheck option.
