okay...
So it's better to work with a native library such as FFMPEG and use it to preprocess the video into frames.

Antoine, please also specify, if you observe the same behavior for all INSV files that are captured by your cameras, or the problem is observed only for the large files above certain file size?

same behaviour and console error for all those files showed in that attached screencap

Maybe it would be helpful to take a look at the following video:
https://www.youtube.com/watch?v=fwjS1CdGl5Q

Author suggests (at about 24 minute) to use the frames from each camera separately and split the calibration groups, also to set Fisheye camera type prior to the alignment process.
Video also includes the control and check points for the accuracy validation.
If interested, you can scroll to the end when proper processing approach is suggested (https://youtu.be/fwjS1CdGl5Q?t=1440) to check the results and error values on check points.

hello Alexey,
METASHAPE v2.2.2 ( build 21287 ) is reporting that issue when importing directly INSV file format in video importer

Error: Can't read video: La demande est incorrecte dans l'état actuel (0xC00D36B2): C:/Users/VID_20251007_105403_00_015.insv

do you have any idea ?

As a rule of thumb, generally, with insta360 product, just changing *.INSV extension to *.MP4 make it avalaible for parsing the video.

Python and Java API / Re: Changing coordinate system on all cameras

« on: May 11, 2023, 07:03:45 PM »

thank you Paul for that reply.

I am not sure I understand the  Metashape.Matrix.Diag((1, -1, -1) ... whereas on other post on the same topic it's a 4x4 matrix being used such as  Metashape.Matrix.Diag((1, -1, -1, 1)

by the way, that post https://www.agisoft.com/forum/index.php?topic=13611.msg60200 should also be helpful as we work with pandas as well.
with that code we can afterward discriminate sensor model as well in the DataFrame written.

hello Paul,
I wanted to follow up that previous reply

but I would like to slighlty change it :
I wanted to apply GNSS leverarm before printing source and target coordinates.

I already setup camera.sensor as well as camera.antenna.rerefence vector
something like that
sensor.antenna.location_ref = Metashape.Vector([0.000, -0.005, 0.068])

so how to apply GNSS leverarm ? If I am not wrong, GNSS leverarm vector is given in camera ref system model.
I understand we must work in LSE (Local Space Euclidean coordinate system) if my source coordinate are given in geographic coord (lat ; long ; ellipsoid height)

So should I do that in 2 steps ?
express antenna leverarm in LSE
apply conversion from lat,long,ellip_h into LSE ?

also , is chunk.updateTransform() needed after step 1 ? step 2 ?

thx
antoine

Hello Paulo,
 do you have any idea how we can use or adapt your script to apply modification of animation from cameras enabled in a chunk, and not using POSE of disabled cameras of the chunk.

in other word, do not consider disabled cameras of chunk when applying your script.
thank you.

Feature Requests / Re: Iterative Closest Point Algorithm

« on: February 16, 2022, 07:07:26 AM »

Dear all,
I was wondering if the alignement of the photo was automaticcally update when using that ICP script ?
I mean : if I am aligning a 3D model on a pointcloud, I guess the images (in the chunk containing that 3D model) are directly rotated and translated ?
by an additionnal command in the script ?
should we update the pose of each image ?

thanks for your comments.

Dear all
if I want to proceed to the same idea but on Pointcloud and not mesh or 3Dmodel, which argument should I use instead of chunk.model.vertices in that Seboon's SCRIPT ?

is it chunk.pointcloud.points ?

thanks

General / Export tiled model to Cesium ion

« on: October 20, 2021, 11:32:29 PM »

Hi Filsun,
I confirm, same issue with me.
In AGISOFT I am searching how we can apply a shift in Z before uploading to CESIUM
maybe the easiest way is to find in Agisoft Reference Setting WINDOW if there is an dedicated EPSG code that would correspond to your planimetric local Ref Frame + ellipsoidal height.
Cesium only accepts ellipsoidal height...
Does Agisoft understand combination of EPSG code ?  such as <planimetric EPSG code> + <altimetric EPSG code>

Hello Paul
I need to perform the same task
I wanted to ask if you can clarify your modification you pointed out in your last post

so I changed
Code: [Select]

coord = T * point.coord

with
Code: [Select]

V = chunk.transform.matrix * point.coord
V.size = 3
X, Y, Z = chunk.crs.project(V)

As you introduce

Code: [Select]

V = chunk.transform.matrix * point.coord
V.size = 3
X, Y, Z = chunk.crs.project(V)
I was wondering if  you still use

Code: [Select]

T = chunk.crs.localframe(T.mulp(chunk.region.center)) * T
THANKS
