Where did you get the camera module(s)?
From Arducam 1MP*4 Quadrascopic Camera Bundle Kit for Raspberry Pi, Nvidia Jetson Nano/Xavier NX, Four OV9782 Global Shutter Color Camera Modules and Camarray Camera HAT
Model number of the product(s)?
What hardware/platform were you working on?
Problems you were having?
I found huge latency from image. I use OpenCV to capture the image and show on the screen and also use visual-inertial odometry to estimate the delay.
I found the image has >150ms (near 170ms) time delay from it captures.
I use the code here to view
MIPI_Camera/arducam_displayer.py at master · ArduCAM/MIPI_Camera · GitHub
Also my own ros node for capturing
GitHub - HKUST-Swarm/arducam_ros: arducam driver for ros.
I test the time delay by capture image, as shown below:
I also use VIO (GitHub - HKUST-Aerial-Robotics/VINS-Mono: A Robust and Versatile Monocular Visual-Inertial State Estimator) to test the delay, and it’s shown to be near 170ms also
- What help do you need?
Time delay of image is critical for our UAV platform. Is this possible to reduce the delay?
