SLAM结果评测工具——TUM Banchmark & EVO

1.TUM评估工具：

absolute trajectory error (ATE) and the relative pose error (RPE)

python associate.py rgb.txt depth.txt > associate.txt

python generate_pointcloud.py rgb.png depth.png  res.ply

ATE：

python evaluate_ate.py groundtruth.txt estimated.txt --plot PLOT

python evaluate_ate.py groundtruth.txt estimated.txt --max_pairs 10000 --plot figure.png --offset 0 --scale 1 --verbose

RPE：

python evaluate_rpe.py groundtruth.txt estimated.txt --fixed_delta --plot figure.png --offset 0 --scale 1 --verbose

2.EVO评估工具：

evo_ape - absolute pose error (APE) and evo_rpe - relative pose error (RPE)
安装：
pip install evo --upgrade --no-binary evo

pip install evo --upgrade --no-binary evo --user

使用：

cd /home/hong/Desktop/drawtrajectory/EVO

评测轨迹：

evo_traj tum groundtruth.txt estimated.txt --ref groundtruth.txt -va -p 
--plot_mode=xz

evo_ape - absolute pose error：

evo_ape tum groundtruth.txt estimated.txt  -va -p 

evo_rpe - relative pose error：

(保存结果为ZIP文件)

mkdir results 

evo_rpe tum groundtruth.txt estimated.txt  -va -p --save_results results/result1.ZIP

将ZIP结果存为table.txt

evo_res result/result1.ZIP -p --save_table results/table.txt

evo_traj kitti KITTI_00_ORB.txt KITTI_00_SPTAM.txt --ref=KITTI_00_gt.txt -p --plot_mode=xz

不同格式的轨迹文件及相互转换：
Examples：

evo_traj euroc data.csv --save_as_tum
