## Keynote “ - [Keynote](https://github.com/dennewbie/AI_Watch_A1/blob/main/caruso_denny_tesi_bsc_cs_keynote.pdf) - [Graduation Day](https://www.youtube.com/watch?v=_YaRFdXXQnY) ## Demo ’ - [Demo #1](https://youtu.be/Ac0V8Dj0FbI) - [Demo #2](https://youtu.be/pq3m9U3hRrQ) ## Docs “ - AI Watch A1 documentation was generated using [Doxygen](https://doxygen.nl/) - Bachelor Thesis in Computer Science: [PDF TesiOnline](http://www.tesionline.it/default/tesi.asp?idt=57417) ## Installation Note: Instructions for MacOS with Intel CPU / M1 chip 1. Install [RealSense SDK 2.0](https://github.com/IntelRealSense/librealsense) and its own dependencies. The following guides are really helpful: [build RealSense for macOS Monterey (Intel + Apple Silicon)](https://lightbuzz.com/realsense-macos/), [macOS installation for Intel RealSense SDK](https://dev.intelrealsense.com/docs/macos-installation-for-intel-realsense-sdk). 2. Install [OpenPose](https://github.com/CMU-Perceptual-Computing-Lab/openpose) and its own dependencies. Useful guides: [build openpose with/without GPU support for macOS](https://medium.com/@alok.gandhi2002/build-openpose-with-without-gpu-support-for-macos-catalina-10-15-6-8fb936c9ab05#726f), [OpenPose for M1/Intel](https://blog.csdn.net/qq_27180763/article/details/126134888?utm_medium=distribute.pc_relevant.none-task-blog-2~default~baidujs_utm_term~default-0-126134888-blog-122796729.pc_relevant_layerdownloadsortv1&spm=1001.2101.3001.4242.1&utm_relevant_index=3). In order to properly choose the `GPU_MODE` during OpenPose installation and/or in order to install OpenPose on other operating systems, check out this page: [OpenPose Docs](https://cmu-perceptual-computing-lab.github.io/openpose/web/html/doc/md_doc_installation_0_index.html). If you have MacOS with Intel CPU and a GPU that matches OpenPose prerequisites, then you can set `GPU_MODE` to `OPENCL` (GPU-accelerated, it is harder to install but provides a faster runtime speed). Otherwise, if you have a MacOS with M1 chip, it's suggested to set `GPU_MODE` to `CPU_ONLY`. CMake Settings for Intel: CMake Settings for >= M1: 3. Install [Apache Kafka](https://kafka.apache.org/), [Confluent](https://www.confluent.io/) and their own dependencies. Confluent is not mandatory, but without it, you will have to set up the Kafka environment on your own. Useful guides: [how to install Apache Kafka on Mac](https://www.conduktor.io/kafka/how-to-install-apache-kafka-on-mac), [how to install Confluent](https://docs.confluent.io/4.0.1/installation/installing_cp.html). 4. Run the following command in your terminal: ``` git clone --recursive git@github.com:dennewbie/AI_Watch_A1.git ``` After that, remove all the files named `emptyFileForPadding.txt` in the cloned folder. 5. From `/AI_Watch_A1/src/AI_Watch_A1/` folder, run the following commands in your terminal: ``` mkdir build && cd build ``` 6. Copy OpenPose's `models` folder to the project's build folder. 7. Copy OpenPose's `BoostConfig.cmake`, `FindGFlags.cmake` and `FindGlog.cmake` files to the `build/cmake/modules/` folder. 8. Update `caffe lib` path inside `CMakeLists.txt`. Then run the following commands in your terminal: ``` cmake .. && make -j `sysctl -n hw.logicalcpu` ``` 9. This step is optional. Run the following command in your terminal: ``` sudo make install ``` 10. Now let's start the Kafka environment. Run the following commands in a new terminal session located on the parent folder of the `confluent` folder. Set the environment variable for the Confluent Platform home directory: ``` export CONFLUENT_HOME=confluent-7.2.1 ``` Add the Confluent Platform bin directory to your PATH: ``` export PATH=$PATH:$CONFLUENT_HOME/bin ``` Test your installation by running the confluent command: ``` confluent --help ``` Your output should show the available commands for managing Confluent Platform. Start Confluent Platform by using the Confluent CLI confluent local services start command. This command starts all of the Confluent Platform components, including Kafka, ZooKeeper, Schema Registry, HTTP REST Proxy for Kafka, Kafka Connect, ksqlDB, and Control Center. ``` confluent local services start ``` Your output should resemble: ``` Starting Zookeeper Zookeeper is [UP] Starting Kafka Kafka is [UP] Starting Schema Registry Schema Registry is [UP] Starting Kafka REST Kafka REST is [UP] Starting Connect Connect is [UP] Starting KSQL Server KSQL Server is [UP] Starting Control Center Control Center is [UP] ``` ### Important #1 “ The confluent local commands are intended for a single-node development environment and are not suitable for a production environment. The data that are produced are transient and are intended to be temporary. For production-ready workflows, check [Confluent website](https://www.confluent.io/). ### Important #2 “ The Confluent CLI requires Java version 1.8 or 1.11. See [Confluent versions interoperability](https://docs.confluent.io/current/installation/versions-interoperability.html). ### Important #3 “ In order to improve speed and general performance, you could disable images' showing and change the number of frames captured per second. In this last option, capturing too few frames per second reduces output' quality. Furthermore, it's also possible to reduce OpenPose's network resolution, but a significant drawback is reduced accuracy. ### Important #4 “ Place the camera in a way that it can "see" the left and the right wall of the room. 11. Navigate to http://localhost:9021 and create a new topic `topic1` with default settings. Now go to `/AI_Watch_A1/src/AI_Watch_A1/` and set up your [Kafka](https://github.com/edenhill/librdkafka) parameters within the `configuration_file.ini` file. At this point: - if internal OpenPose execution is chosen, then run the following command in your terminal: ``` sudo ./AI_Watch_A1.bin --num_gpu 1 --num_gpu_start 2 --image_dir rs_images/rgb --write_json op_output/op --logging_level 255 ``` - if external OpenPose execution is chosen, then set up your OpenPose parameters within the `conf.conf` file, run the following command in your terminal: ``` sudo ./AI_Watch_A1.bin ``` Note that the internal OpenPose execution is suggested. ## Known issues 1. The module can rarely get stuck on the following invocation located in `RealSenseD435Manager::23`: ``` rs2::pipeline_profile myPipelineProfile = pipelineStream.start(myConfiguration); ``` This means some errors have occurred, due to the USB connection while starting the camera's environment. In order to fix that, just exit the program, unplug the RealSense camera from the USB cable, and connect it again. ## System Structure
