Best low-cost cam that can match the *still photo FOV* of a Hero 4 Black (not the quality)

    Here's the revision you asked for. I'm modifying my panohead for an extra lateral row that I hope will compensate for the limited FOV of other cameras and perhaps deal with the stitching problem that I think is caused by lens distortion at wider FOVs.

      Thanks. That means you've got the Sony IMX206 sensor under the hood. It does not really make sense for pano shooting use, but some script image quality adjustements will vary.

      So, you're making 3x4 head, right?

      So, if that sensor is not good, is there a cheap Yi that has a decent sensor?

      The IMX206 sensor is good enough for pano shooting. Newer Yi revisions have 16Mp Panasonic MN34120 which is slightly better for low-light shooting.

      Would that include the Yi Lite? I can't tell on some spec sheets if it has a Sony sensor or a Panasonic sensor.

      The Lite cam is also based on the IMX206, but the SoC provides very limited functionality comparing to the original Yi camera. First of all I'm talking about scripts.

  • #17
    Yeah. That's the dream anyway. I'll see if I've got it right this evening when I finish printing the new design.

      Indeed! I got tired of paying to get things made. Too expensive. I can rapid prototype for a fraction of the cost.

    Here's my test with the Yi: https://kuula.co/post/7Y5jF

    It almost, almost worked with the Apexcam, but there were still a few holes in the pano that needed filling. But very close and makes me think if it was 3x5, it would work.

      Here's the thing I don't understand. This Yi has a 150-degree FOV lens, right? Then why don't cameras that claim to have 170-degree FOV produce photos with even better overlap?

      Looks nice!

      Today I tried 5+1 setup (5 portrait pano shots in one row with 72-degree gaps + 1 to the zenith). Seems to be very effective (~70MP) considering only 6 shots are needed. Unfortunately it is very hard to stitch it right when using 2 cams: one with ~120 HFOV for 5 radials and another one with much wider (~150 degree) lens for the zenith.

    I finished printing my pano mount for a very cheap, limited FOV cam. The differences in ISO setting are apparent. It's clearly not a good camera, with odd solarization effects and terrible noise, but that wasn't the main aim here - it's to see if I could put practically any action cam in the mount and produce a reasonable 360x180 pano.

      This is the cam plus my latest pano head design, freshly printed. So, I'm thinking a Yi Lite as my bare minimum for photo quality. What I did like about this cheapie Apex Cam is the wristband remote. I wish Yi had them. I want simplicity for student users.

        The Yi BT remote costs ~USD 4-5 and it can be used with a Xiaomi Band bracelet for another 0.50.

        That looks great! I like the aspect as well. You've got lots of cool archaeology to capture. I'm switching back to the Yi myself, now that I've proven that a very cheap action cam can do the job with the right pano head. I'm going to start playing around with scripts and such to get better quality out of the camera. It won't quite match the GoPro, but it should do ok. What have you been using in the past to do your panos?

      I belive it's possible to leave the gopro behind.

      I'm not quite sure about what you mean. I've shot my first pano ever something like ten days ago.

        Sorry, when I looked at your pano of the ruins, it seemed to be in a set of Google Streetview images under one username that dated back quite a while. But I guess they were other people's images.

        So, what's the best script to use for better panos on the Xiaomi Yi Action Cam (for the one I'm using)? I want HDR if possible plus exposure lock.

        I think 6 exposures are not needed here. 3 or even 2 (one slightly under- and one overexposed) would be enough.

        Yes. Very easy stitching. No adjustments at all.

      DJI has released its Osmo Pocket action camera with automatic 3x3 pano shooting and stitching. The cam seems to be based on the newest Ambarella CV22 SoC and Sony IMX377 CMOS sensor.

        Yes I saw. It's clever repackaging because it's really a repurposed drone camera and gimbal.

        Oh, that's just a random link I threw up there. I'm not actually sure what wood particles are in the filament that I'm using. But it smells so much better than ABS. If I'm printing the latter I usually cover up the printer and close the door.

      BTW, I'm using your HDR-EXPO-3 script and it's excellent - it's ideal for students who just need a simple process to capture good quality shots. But I'd like to add the capability to capture RAW. Is that an easy addition?

        Adding some strings, removing some strings, adjusting delays for saving more data. Not a big deal. I'll share the script with RAW support soon.

        Cool. I have also seen someone post about a 'superview' setting in a script (or firmware?) as well. That might roughly correlate to what I'm getting out of the GoPro and might reduce the number of shots necessary.

        That's not a real 'superview'. A simple aspect ratio trick with full-frame 4:3 image resized into 16:9 ratio. Worked for videos only as we already get 4:3 for stills.

      You can try reducing the sleep X values after #data saving delay if your memory card is fast enough.

      In the meantime, here's a pano I created today. Bridge in the distance is a little blown out but I think that the HDR might give me a better chance of retrieving the detail and correcting exposures if I can do the same shots again tomorrow.
