Camera

• 新增test.cpp 使用 thread 讀buffer 但是速度一樣慢

Resource

• Camera: https://github.com/quic/sample-apps-for-Qualcomm-Robotics-RB5-platform/tree/master/camera-hal3-sample
• Image_transport: http://wiki.ros.org/image_transport/Tutorials/PublishingImages

Build

1. mkdir -r catkin_ws/src
2. cd catkin_ws/src
3. git pull ***
4. cd catkin_ws && catkin_make

Run

1. cd catkin_ws

• ( [camera id] [yuv420_8bit_previwe_weight] [yuv420_8bit_height] [jpeg_weight] [jpeg_height] )

3. ./build/stream_hal3 0 1920 1080 1920 1080

Function

• Save image flie (Streamming) to folder (build/CAPTURE/***.yuv or ***.jpg)

• Run with ROS command (rosrun) --> not working

• but use "stream_hal3" command to stream to ros

• OPENCV read image file (build/CAPTURE/***.yuv or ***.jpg) to ROS

  • Read JPG with opencv read with encode format "bgr8" is OK
  • but YUV with opencv read with encode format ---> still not working

• OPENCV read buffer(from memory to ROS)

  • although I have added code and build success, but have not tested the result yet.
