A video based fall detection approach and a fall detection system on ROS based on single image.

Posefall

This repository contains two fall detection projects.

The first one is a video-based fall detection approach https://arxiv.org/abs/2107.14633, which takes 300 frames of 2D poses to detect whether there is a fall behaviour. The experiments were conducted on NTU RGBD dataset, we refer to codes from https://github.com/kchengiva/DecoupleGCN-DropGraph to train and evaluate our model. Only codes for our fall detection model is provided in this repository because...I'm lazy... Cleaning up the codes is quite time-comsuming and my research interest is not action recognition.

2023.2 new! I have uploaded codes for video-based fall detection, however, I do not clean them, hope they would help. https://drive.google.com/drive/folders/1wQz-TSld67ZZljYgCtfUKhjscvpAMOr2?usp=sharing

The other is a fall detection system on ROS based on single frame 2D pose. Here is the demo: https://www.bilibili.com/video/BV1AT4y1u7t3/ Pretrained weights can be found here: https://drive.google.com/drive/folders/1s1hcetDzHP6DlVecV3Zj199TVsDVsjLI?usp=sharing

I do not plan to update this repository detaily, you can send messages to me if you are interested in this work.

Tips for "ROS_fall_detection": Remember to modify the first line in "cam.py" and "detector.py": #! /home/seanchen/anaconda3/bin/python. Change it to your own Python3 path as our rep uses pytorch with Python3, while original ros is based on Python2.

posefall's Issues

I have a quick question!

First, Thanks for your awesome work ! :) I'm really impressed on your research. I thouht this model works on vedio. Then, I have a quick question. am i able to use this model with the camera? I would like to adopt this model in my own camera. Can I ?

pre-trained weights for fall detection

Hi, @SeanChen0220

Could you share your weights and guide me ho to test my own videos with that. I may further work on fall detection task, so therefore I need some demo for my videos. Thanks!

I can't find the code for video detection

if can't locate ROS_fall_detector , rename it to lowercase

I'm new to ROS and hopefully this tip would help out someone like me :)

After I cloned this repo and ran catkin_make in my workspace, everything looked fine. However, I failed to use roslaunch to run this node or use roscd to locate it.

All problems were solved after I rename ROS_fall_detector to ros_fall_detector(or anything that is lowercase).

Incompletion of the video based fall detection

Hello
How are you?
Thanks for contributing to this project.
Did u share a model for the video based on fall detection?
Could u add a script for demo of the video based fall detection?
Thanks

Can you please guide how to implement the system?
