kitti_native_evaluation

This code is based on Bo Li's repository: https://github.com/prclibo/kitti_eval with the main differences being some code cleanup and additional AHS metric described in our paper: Joint 3D Proposal Generation and Object Detection from View Aggregation

evaluate_object_3d_offline.cpp evaluates your KITTI detection locally on your own computer using your validation data selected from KITTI training dataset, with the following metrics:

• overlap on image (AP)
• oriented overlap on image (AOS)
• overlap on ground-plane (AP)
• oriented overlap on ground-plane (AHS)
• overlap in 3D (AP)
• oriented overlap in 3D (3D AHS)

Compilation:

Clone the repo using: git clone https://github.com/asharakeh/kitti_native_evaluation.git

From inside the main folder do:

1. cmake ./
2. make

Usage:

Run the evalutaion by:

./evaluate_object_3d_offline groundtruth_dir result_dir

Note that you don't have to detect over all KITTI training data. The evaluator only evaluates samples whose result files exist.

Data Format:

The detection format should be simillar to the KITTI dataset label format with 15 columns representing:

Values	Name	Description
1	type	Describes the type of object: 'Car', 'Van', 'Truck', 'Pedestrian', 'Person_sitting', 'Cyclist', 'Tram', 'Misc' or 'DontCare'
1	truncated	-1
1	occluded	-1
1	alpha	Observation angle of object, ranging [-pi..pi]
4	bbox	2D bounding box of object in the image (0-based index): contains left, top, right, bottom pixel coordinates
3	dimensions	3D object dimensions: height, width, length (in meters)
3	location	3D object location x,y,z in camera coordinates (in meters)
1	rotation_y	Rotation ry around Y-axis in camera coordinates [-pi..pi]
1	score	Only for results: Float, indicating confidence in detection, needed for p/r curves, higher is better.

Example:

type	truncated	occluded	alpha	bbox	dimensions	location	rotation_y	score
Pedestrian	-1	-1	0.29	873.70 152.10 933.44 256.07	1.87 0.50 0.90	5.42 1.50 13.43	0.67	0.99
