BEST way to use fSpy | ALL Options explained | FULL camera matching workflow with Blender

Күн бұрын

If you’ve ever struggled with fSpy, had trouble getting a perfect match, and wondered why following tutorials doesn’t work for you - watch this.
You'll learn:
* what every single fSpy option means
* what are the common mistakes people make (both in fSpy and in Blender)
* how to deal with cropped images / shifted camera
* how to find the principal point (for 1-, 2- and 3- point perspective)
* how to determine the focal length if it's unknown
* why modeling from a 2-dimensional picture can lead to wrong object placement, and incorrect dimensions
* why setting the reference distance isn't enough
I believe this is the most complete fSpy tutorial at the moment and hope it will help you with your non-trivial images.
0:00 - Intro
1:51 - Common mistakes with vanishing points
3:09 - Proper way to establish the vanishing points
7:01 - The Principal Point
8:39 - Matching the principal point
9:09 - 3-point perspective
10:38 - 2-point perspective
14:45 - 1-point perspective
16:17 - Problem with Field of view
16:53 - FOV vs Focal Length
17:32 - Determining Focal Length
21:54 - Matching dimensions
24:52 - Draft modeling
25:19 - The biggest mistake & the importance of depth
26:26 - Modeling the right way
29:37 - Blender Snapping Tips & Tricks

Thanks to this I've been able to use fSpy on pictures of complex parts on a plain background. There are no parallel lines to speak of, so you have to draw between aspects of the part you know to be parallel (i.e. mirrored about one of the axes) using the single vanishing point method. Very happy with the accuracy of the outcome, and it makes non-orthogonal reference photos more useable e.g. for CAD even.

Really great tutorial. In the "swimming pool" image, there is a way to find the exact position of the principal point. Unfortunately this is not possible with fSpy. But with some descriptive geometry, you now can find the exact location of the principal point on the horizon line (Horizon is determined by the two vanishing points). Because the lower two sun loungers are rotated in relation with the rest. The corners of the loungers are 90 degree (assumption). This rotation gives enough information for solving the principal point. It is too complicated to explain here. You need 2d-CAD software for this. Thank you for this tutorial with explanation and no cheating. 🙂

@bpampuch Жыл бұрын

What a fantastic idea for the principal point. I’d have never thought about doing it this way. Do you know any publications with appropriate math for this? It would be great to extend fSpy with such functionality

@Hsubetakevol Жыл бұрын

@@bpampuch In this case It is a 2 point perspective (with vertical parallel lines) and something that is rotated with a straight angle. In a 2 point perspective, the principal point is always on the horizon line. How to find the location for the principal point on the horizon line in this case: Draw a continuous line through the 2 vanishing points (horizon line). Take the midpoint between the two vanishing points. From this midpoint draw a circle through the vanishing points. Now draw the vanishing lines from one of the the lower sun loungers. This two new lines will intersect with the horizon line. Take the midpoint between these intersections. From this new midpoint, draw a second circle trough these intersections. Now there are two circles. These circles intersect each other. Draw a line through the intersection of these circles perpendicular to the horizon line. This line will intersect the horizon line. This intersection is the principal point.

@Hsubetakevol Жыл бұрын

Also a publication for finding the principal point: www2.mathematik.tu-darmstadt.de/~ehartmann/dga-incl-loes.pdf (german, but with images) page 126, 127 and solve on page 181, 182 But they are different from this case.

If lines aren't parallel they'll converge at some point so you should count this as a normal vanishing point (even if it's not within the image boundaries). I hope it helps ;)
