Computree SimpleTree plugin - new Release Beta_14 - plot level QSM processing

Added by Hackenberg Jan over 3 years ago

Dear Users,

Short announcement

About the release:

- Improved fit quality, also for small trees again.

- I added a few steps to make plot level analysis more comfortable. There is one step included which can get rid of segmented undergrowth.

- I did not change the output csv files and try to also further not do so. Your analysis scripts should still work hopefully, if not give me feedback.

- From what I can tell my modelling is now unfortunately 20% slower. I am sorry, but the fit quality justifies this.

- If you work on plot level, outputfiles created adapt their name from your plot cloud. I hope this makes data management easier

- I created another tutorial video and 3 step configuration files.. Alexandre has also a youtube channel (https://www.youtube.com/channel/UCAs1tLPP-X-DQ-oBf71FlfQ) where you find the old tutorials in higher quality as well as the new one once uploaded.

- If you are not in the finish line of a master thesis (or something similar with heavy time constraints) I highly recommend using this version...

- You do not have to give any more a cut height in the plot level pipeline (so no csv file anymore needed). I hope my automatic prediction is more accurate than what I had to do also myself manually.... You still need the file if you go for the single modelling step...

- If you work in mountaineous areas I expect the modelling quality to drop (problematic DTM maybe). Up to you if you prefer manual segmentation in CloudCompare and work with the single tree modelling step.

- I will work on leaf denoising next. Crownprojection area and fixing the above mentioned DTM issues are also on my list.

- If you are interested in tree archtecture rather than DBH + volume + height, look at the ply files in .../my_output_folder/ply/detection. Branch angles, segment length ect are not good for the green cylinders (as you already might have observed). You should remove them in your R analysis (row in detailed file with header detection tagged with spherfollowing is fine, kick out the others). Those cylinders just give a better total volume but the topological information is bad. That is why length is still hugely overestimated and you should work with height.

Thank you to all of you

Jan

Beta 15 released, minor bug fix release

DBH, height and length (the last was unusable until now, the first two had still a minor error) are predicted now correctly. In addition cut height is added to the plot level output.
