General / Re: Intelligent scissors are not Intelligent

Hello Steve,

I think the following video is quite similar to the one you have posted in another thread but also gives and idea of Intelligent Scissor masking:

Left-click on the first point, hold CTRL, move the cursor along the edge of the object, left-click again quite regularly to avoid "straight lines" drawing.

Hello Steve,

Magic wand tolerance options are available in the version 1.4.5 and even in 1.2.6.

Scissors instrument may get confused, if there are considerable contrast changes in scene by the borders of the objects or elements in the background.

You can import the masks from the external source (separate set of black&white images or from the alpha channel i.e. transparency channel), if you prefer external applications for mask drawing and find them more convenient for your needs.

Hello harmbrar,

Can you post the code block that you are using to build the dense cloud and mesh in the certain chunk-duplicate?

Hello Paul,

Accuracy value in meters define, how accurately the reference values are measured. If the offsets are within a couple of cm, then would rather suggest to input 0.05 m value instead of 5.0 m.

Hello godszerg,

You can use try-except approach to skip the chunks with "Zero Resolution". The simple example:

Code: [Select]
except Exception:
    print("Skipping " + chunk.label)

Hello Steve,

OK, thanks, I'll check the status of your tickets and the provided data.

General / Re: can I have both 1.2.6 and 1.4.5 installed to use both ?

Hello Steve,

You  can have both versions installed on the same computer, just move the installation directory of the older version to some custom location, before installing a newer one to the default location.

As for the problems that you are observing, it would be helpful, if you can provide an example of the image set that can be properly aligned in the version 1.2, but fails (or produce wrong result) in the versions 1.4, 1.5.

Hello Steve,

If you have problems with the image matching and alignment on certain datasets in the versions 1.4 and 1.5, but can properly align the cameras in the version 1.2.6, then could you please send the example of such image sets to, so that we could reproduce the difference on our side and check if anything should be fixed in the algorithms?

Добрый день,

Ограничить область обработки с помощью векторных границ в настоящее время нельзя (область ограничивается только рабочим объёмом в форме прямоугольного параллелепипеда). Однако, для экспорта можно применить полигональные границы в виде нарисованных или импортированных фигур.
Для задания фигуре свойство "границы" нужно открыть режим просмотра Орто, выделить (сделать активным) нужные полигональные фигуры, зайти в контекстное меню для выделения по правому щелчку мыши и выбрать пункт "Задать тип границы" для данных фигур.

Полигоны со свойствами границы будут автиматически применены при экспорте облака точек, ортофотоплана, ЦМР и тайловой модели.

Hello Sébastien,

You can send the project file in PSZ format with the alignment results and mesh model (depth maps and dense cloud are not required), so that we could reproduce the problem on our side.

Hello Paulo,

The offsets between the sensors in MicaSense cameras can be usually neglected. If you are still interested in those offsets estimation, I would suggest to input the Reference data and accuracy that corresponds to the real values.

Hello Sébastien,

I've checked masking from model on some random project and haven't observed this issue. So in your case it could be caused by the incorrect alignment for some cameras.

Do you face the same problem in other projects?

Hello SamT,

Code: [Select]

Bug Reports / Re: Masking photo bug
« on: June 24, 2019, 08:45:46 AM »
Hello Sébastien,

Please check the latest hot-fix update:  1.5.3 build 8469. The masking issue should be fixed there.

Hello Steve,

If you have the possibility to apply the masks to all the images (for example, using From Background option) then just align the photos in the single chunk using Apply Masks to Key Points option.

Alternative way would be masking the static background just on a few images and using Apply Masks to Tie Points approach:

Usually alignment of the cameras in the single chunk gives better accuracy and quality of the results, rather then alignment of the multiple chunks.
