Notes:

1. I made some modifications to the instructions. To use the newer version of Meshroom (Meshroom-2021.1.0-av2.4.0-centos7-cuda10.2), I needed to run the following command instead of input.sh:
   /data/Meshroom-2021.1.0-av2.4.0-centos7-cuda10.2/meshroom_batch --input input/ --output output/ --save project.mg --overrides overrides.json
   Bear in mind that for large numbers of photos this could take several hours to run, which can easily cause your spot instance to fail. If this happens, try to modify the overrides.json file with more aggressive settings so that the process can finish faster.

overrides.json (adapted from https://peterfalkingham.com/2021/03/02/meshroom-2021-1-0-whats-new-and-what-parameters-to-tweak/):
{
"FeatureExtraction_1": {
"describerPreset": "low",
"forceCpuExtraction": false,
"contrastFiltering": "AdaptiveToMedianVariance"
},
"DepthMap_1": {
"maxViewAngle": 30,
"downscale": 4,
"nbGPUs": 1
},
"DepthMapFilter_1": {
"maxViewAngle": 30
}
}

Notes:

1. Although the controller allow for idle regeneration, since I'm using a rectified supply, I can't actually push the current anywhere, so, for this test, I have extremely low regeneration set
2. The controller doesn't seem to be capable of regenerative braking in reverse. I will investigate.
3. The controller used is a Thunderstuck Dilithium VCU (https://www.thunderstruck-ev.com/dilithium-vcu.html). It is designed for the second generation EM57/inverter (for generation 1 ZE0 Nissan Leafs from 2010 to 2017. Confusing, I know), as well as UQM or Coda Motors.
