Environment

This repo is developed under the following configurations:

  • Hareware: Centos 7, 4 NVIDIA P4 GPUs

  • Software: Python=3.6.7 GCC 5.4.0 paddle=1.7.0 CUDA=9.0

We provide a docker image for official test for track-1 datasetB.

Download via https://bj.bcebos.com/v1/baixue/liuzhongji/aicity2020_task1_counting.tar

We also provide our label of datasetA for fineturning vehicle detector.

Download via Baidu Cloud: [https://pan.baidu.com/s/1o8QMCubHCO6dTTSELCcNuA passwd: r08r]

where:

train.tar -- selected frames from datasetA

1584811984_train_final.json -- label

faster_rcnnn_r50_track1.tar -- configurations for fineturning

####How to run:

  • load the docker image and create a docker container(or prepare paddle environment follow this)

docker load < baidu_aicity2020_track1.tar

nvidia-docker run --name aicity2020_task1 --shm-size 16G -it aicity2020:track1

docker attach aicity2020_track1

the code is in the path: /home/task1_code, the cuda env file is in the path: /home/cuda

  • prepare the dataset( copy the whole dataset of "AIC20_track1" to /home/task1_code* )

  • prepare the run env: cd /home/task1_code && source set_env.sh

  • modify the path of list_video_id.txt in: (1) run_pipeline.sh ; (2) vehicle_counting/counting.py

  • run the whole pipline: sh run_pipeline.sh

the steps and related folders included in the whole pipeline:

  1. **extract_frames.sh: **extract images from videos in dataset like "AIC20_track"
  2. **run_detection.sh: ** /home/task1_code/PaddleDetection is the folder where we run detection model, the origional /tools/infer.py, which you can find at paddle detection is modified to save detection results in txt format. The detection results will be saved in /home/task1_code/det_results/
  3. **run_tracking.sh: ** /home/task1_code/tracking is the folder where we run online tracking method, the tracking results will be saved to txt files in /home/task1_code/track_results/
  4. **run_counting.sh: **/home/task1_code/vehicle_counting is the folder wher we run counting method, the final counting results will be saved to txt files in /home/task1_code/vehicle_counting_results/
