Budget is tight and I'm looking at OpenDroneMap/WebODM as an alternative to Pix4D or DroneDeploy. I know it's free but how does the accuracy actually compare?
Running on a decent workstation (Ryzen 9, 64GB RAM, RTX 4080). Mostly doing construction topo and stockpiles.
Anyone made the switch? Or tried both side by side?

Sign inThe accuracy is there if you configure it right. Default settings won't give you survey grade. You need to tweak the processing parameters. Happy to share my settings if you want.
I ran the same dataset through WebODM and Pix4D last month. Results were surprisingly close - within 2cm on checkpoints. WebODM took about 40% longer to process though.
The real difference is workflow and export options. Pix4D just has more polish and better Civil3D integration.
For stockpiles it's totally fine. I switched to WebODM for routine volume work and kept Pix4D for the complex stuff. Saves about $3k/year in subscription fees.
