            Padding scipy affine_transform output to show non-overlapping regions of transformed images
            Asked 2022-Mar-28 at 11:54

            I have source (src) image(s) I wish to align to a destination (dst) image using an Affine Transformation whilst retaining the full extent of both images during alignment (even the non-overlapping areas).

            I am already able to calculate the Affine Transformation rotation and offset matrix, which I feed to scipy.ndimage.interpolate.affine_transform to recover the dst-aligned src image.

            The problem is that, when the images are not fuly overlapping, the resultant image is cropped to only the common footprint of the two images. What I need is the full extent of both images, placed on the same pixel coordinate system. This question is almost a duplicate of this one - and the excellent answer and repository there provides this functionality for OpenCV transformations. I unfortunately need this for scipy's implementation.

            Much too late, after repeatedly hitting a brick wall trying to translate the above question's answer to scipy, I came across this issue and subsequently followed to this question. The latter question did give some insight into the wonderful world of scipy's affine transformation, but I have as yet been unable to crack my particular needs.

            The transformations from src to dst can have translations and rotation. I can get translations only working (an example is shown below) and I can get rotations only working (largely hacking around the below and taking inspiration from the use of the reshape argument in scipy.ndimage.interpolation.rotate). However, I am getting thoroughly lost combining the two. I have tried to calculate what should be the correct offset (see this question's answers again), but I can't get it working in all scenarios.

            Answered 2022-Feb-15 at 15:13

            Interesting post. With the problem at hand being illogical, the explaination (or rather my hypothesis due to the lack of documentation) is actually the opposite. In short: Dynamic arrays are the culprit to the difference between ms365's and previous versions of handling each condition in the AND() function.

            First, even though the ms-documentation tells us that all conditions need to evaluate to TRUE, the reality of it is that there are two other important rules for us to keep in mind:

            • Text values or empty cells supplied as arguments are ignored.
            • The AND function will return #VALUE if no logical values are found or created during evaluation.

            Let's assume that with the below examples, the value NY is written in cell A1. In Excel 2019 and earlier versions, you should recieve the following results:

            Formula Outcome =AND(TRUE) TRUE =AND(TRUE,A1) TRUE =AND(TRUE,"NY") #VALUE =AND(TRUE,{"NY"}) TRUE =AND({"NY"}) #VALUE

            Whether it's intentional or not, in versions prior to ms365 any text value will result in an error unless it's written in an array format or pulled in through a cell-reference.

            I can only expect the difference with ms365 to be explained that the latter will automatically evaluate the single text-value as an array due to the mechanics of dynamic array functionality.

            It seems this function is broken in pandas 1.3.0 Just look at this document , when trying to append to existing sheet it will either raise an error, create a new one or replace it

            if_sheet_exists{‘error’, ‘new’, ‘replace’}, default ‘error’ How to behave when trying to write to a sheet that already exists (append mode only).

            error: raise a ValueError.

            new: Create a new sheet, with a name determined by the engine.

            replace: Delete the contents of the sheet before writing to it.

            New in version 1.3.0

            The only solution is to downgrade pandas (1.2.3 is working for me)

            • It's specific to Excel, so I don't know how these results will carry over to Access and other Office programs.
            • It's just a test of a variety of cases. A definitive answer would be based on knowledge of the algorithms used to calculate IsEmpty(), VarType, and TypeName(), and to assign Empty.

            I know that it's way easier to ensure single instances from the class level, and that there's the excellent Staticish module from Jonathan Stowe that does the same by using roles, but I just want to try and understand a bit better how the class higher order working can be handled, mainly for a FOSDEM talk.

            Answered 2022-Jan-16 at 16:02

            There's a few misunderstandings in this attempt.

            1. There is one instance of a meta-class per type. Thus if we want to allow a given type to only be instantiated once, the correct scoping is an attribute in the meta-class, not a my. A my would mean there's one global object no matter which type we create.
            2. The compose method, when subclassing ClassHOW, should always call back up to the base compose method (which can be done using callsame). Otherwise, the class will not be composed.
            3. The method_table method returns the table of methods for this exact type. However, most classes won't have a new method. Rather, they will inherit the default one. If we wrap that, however, we'd be having a very global effect.

            While new is relatively common to override to change the interface to construction, the bless method - which new calls after doing any mapping work - is not something we'd expect language users to be overriding. So one way we could proceed is to just try installing a bless method that does the required logic. (We could also work with new, but really we'd need to check if there was one in this class, wrap it if so, and add a copy of the default one that we then wrap if not, which is a bit more effort.)

            You can do it in only two regex passes. First extract the monetary amounts with a regex, then remove the thousands separators, finally, join the output by group keeping only the first two occurrences per original row.

            The advantage of this solution is that is really only extracts monetary digits, not other possible numbers that would be there if the input is not clean.

            THREE.JS & Reality Capture - Rotation issue photogrammetry reference camera's in a 3D space
            Asked 2022-Jan-03 at 14:57

            Thanks for taking the time to review my post. I hope that this post will not only yield results for myself but perhaps helps others too!

            Introduction

            Currently I am working on a project involving pointclouds generated with photogrammetry. It consists of photos combined with laser scans. The software used in making the pointcloud is Reality Capture. Besides the pointcloud export one can export "Internal/External camera parameters" providing the ability of retrieving photos that are used to make up a certain 3D point in the pointcloud. Reality Capture isn't that well documented online and I have also posted in their forum regarding camera variables, perhaps it can be of use in solving the issue at hand?

            Only a few variables listed in the camera parameters file are relevant (for now) in referencing camera positioning such as filename, x,y,alt for location, heading, pitch and roll as its rotation.

            Currently the generated pointcloud is loaded into the browser compatible THREE.JS viewer after which the camera parameters .csv file is loaded and for each known photo a 'PerspectiveCamera' is spawned with a green cube. An example is shown below:

            The challenge

            As a matter of fact you might already know what the issue might be based on the previous image (or the title of this post of course ;P) Just in case you might not have spotted it, the direction of the cameras is all wrong. Let me visualize it for you with shabby self-drawn vectors that rudimentary show in what direction it should be facing (Marked in red) and how it is currently vectored (green).

            Row 37, DJI_0176.jpg is the most right camera with a red reference line row 38 is 177 etc. The last picture (Row 48 is DJI_189.jpg) and corresponds with the most left image of the clustured images (as I didn't draw the other two camera references within the image above I did not include the others).

            When you copy the data below into an Excel sheet it should display correctly ^^

            Answered 2022-Jan-02 at 22:26

            At first glance, I see three possibilities:

            • It's hard to see where the issue is without showing how you're using the createCamera() method. You could be swapping pitch with heading or something like that. In Three.js, heading is rotation around the Y-axis, pitch around X-axis, and roll around Z-axis.

            • Secondly, do you know in what order the heading, pitch, roll measurements were taken by your sensor? That will affect the way in which you initiate your THREE.Euler(xRad, yRad, zRad, 'XYZ'), since the order in which to apply rotations could also be 'YZX', 'ZXY', 'XZY', 'YXZ' or 'ZYX'.

            • Finally, you have to think "What does heading: 0 mean to the sensor?" It could mean different things between real-world and Three.js coordinate system. A camera with no rotation in Three.js is looking straight down towards -Z axis, but your sensor might have it pointing towards +Z, or +X, etc.

            Edit:

            I added a demo below, I think this is what you needed from the screenshots. Notice I multiplied pitch * -1 so the cameras "Look down", and added +180 to the heading so they're pointing in the right... heading.
