In Houdini, there is no tool via which you can display the correct camera perspective in relation to the photo? In 3ds Max there is a tool Perspective Matching https://www.youtube.com/watch?v=ZX6oUj4k7II [www.youtube.com] There's really no analogue in Houdini? I searched the entire internet and did not find

No, I am afraid there isn't one, although you could build it yourself if you wish (not trivial though).
This should get you started.

Good luck!

Probably not as powerful as Perspective Matching of 3ds max but in soft you have a script that allow to find exact camera focal.

I usually use them for photo matching in soft and it simplify a lot hand matching with the exact 3d camera focal.
It can probably easily by adapted to Houdini.
Of course a complete Perspective Matching tool can be better if you have enough courage !

Thank you! I understand it can be done in softimage and then transferred to Houdini? How is the transfer going?

Hello, this script “just” compute a fixed focal in function of your kind of camera (or with the sensor size if your camera is not referenced).
After, it's just a matter of UI menus to set and autofill 3d camera values parameters.
But you always need to position and orient your camera by hand (anyway, a right focal parameter help a lot !).
Then you can export camera with fbx.
Or just copy paste focal to houdini with a mathematical conversion (cf. this thread for conversion : interesting thread [www.sidefx.com]). And then position and orient inside houdini.
I hope I'm clear.
Cheers
