Export data about laser points automatically detected

[BastienTaormina]

Hello,

I am trying to use Biigle in order to measure the distance between two laser points on ROV recordings.
I am then using the automatic point detection on a lot of images (several thousand in each volume). The algorithm is working pretty well, except a few error.

I would like then to export the data obtained, i.e. for each of my picture in my volume , having the number of pixel calculated between my two laser points. Unfortunately, as the detected laser points are only here to calibrate the picture in Biigle (that's what I understood), these are not considered as "label". So when I am trying to export the data, my file is empty (or almost empty, there is only the points I manually annotated to help the automatic detection). Considering the high number of pictures I am working on, I cannot create manually an object in each picture of the volume.

Thus, I was wandering if there is any method to export the data obtained about the laser points detected?

Don't hesitate if any additional information are needed.

You are right, there is no report that will provide you with all detected laser points if there are no annotations on the image. However, you can fetch the points via the API. Example: https://biigle.de/api/v1/images/2746744/laserpoints

Take a look at the community scripts for Python script examples that use the API.

I am having troubles to access API from R, I thinks it is because I don't know where to find and to add the authentication token...
This is the line I am using to try to access the ID data of my volume:
res = GET("https://biigle.de/api/v1/volumes/8845/images/filter/laserpoints")
Do you have any ideas?

I found a way :)

Great, an R script is totally fine, too. If you like, you could share the final script in the community scripts.

I'm sorry but I just remembered that there is a convert laser points community script. This will transform automatically detected laser points into point annotations so they will be included in reports! It's a Python script, though.

Don't worry, I saw that script during my research but considering that it was Python, I didn't understand. I will try to clean and share my R script for people more familiar with this language!
