Tracking image/horizontal panorama

  • In most phones that have built-in cameras there is a panorama/tracking app that takes lots of slices as you move the camera and stitches them together to form one long image. Normally used to spin on the spot and create panoramas, but it inspired this idea:

    It would be cool if Enscape could create a long 'tracking' image; stitching together vertical strips as it moves the camera from point X to point Y. This could be an easy and initiative way to create long, 'flat' elevations and sections without having to adjust image width/height or trim a larger image or play with fov settings etc.

    Hey Gadget , thanks for the idea, but that would technically not be easy to implement and it would probably not gain enough demand to be considered for a implementation. What would be your use case for this?

  • It's a good/simple way to output architectural elevations, sections and plans without having to change the FOV and set up the perfect camera position (and set the canvas size). It could be set-up with two clicks.

    Technically you could do it just now by setting up the canvas size as a narrow vertical strip and making a "lossless" video, then just stitching the resulting images together. But it would involve a bit of trial and error (or math that is beyond me) to get the frame rate and width of strips to line up properly.

    Currently the panorama feature keeps the camera position static and changes the direction the camera is pointing. Then it runs a render for a strip, then stitches this strip into a combined image. The only change here is that the camera direction is static and the camera position changes.

    The 'preview' of this would be like sitting on the scanning light of a photocopier as it moved - it's designed for output rather than being interactive.

    I understand Gadget , I've filed your feature request accordingly. :) ;) Thanks for the feedback.

  • ? do you mean that if (eg) a tree is close to you in the foreground it will appear stretched along the travel plane? Sure - you might have to be careful of the foreground and perhaps add a cutting plane too but I imagine it would be like the inverse of a photo-finish camera.

  • The problem is the background. Objects far away doesn't change the position at the image, through the slit of your scanner you see nearly the same at every time. Only the foreground is changing. How will you scan a constant background? And the relation of the objects in the foreground to the background is changing. How will you see the background in relation to the foreground? ... Finally you get something like from my experiment - foreground right scanned, background nearly constant as stripe (there should be a sea and trees).

    Here an example, two images - the red object stay in the middle of the image during the foreground is moving. How should the combined image be looking?

    You could try to shot some images from a scene per moving camera and try to combine it to a single view. I think, it will not work.

    I've added your voice to the topic, thanks! :)

  • Yes, however for a parallel projection you would need to set the camera position, FOV, canvas size, active sections, etc. If you just set two end points of a line as a 'dolly rail' to push the camera down, the program would do most of the setup for you; just need to set the lighting.

    Thought I would try a stitched version to see what would happen... (the software I used to crop all the images left a watermark streak. I deliberately set a path that was *not* parallel to the building to see what the distortion looked like)
