Increasing horizontal_hov in gazebo will make the object looks very "far" [closed]
Hi everyone, I have a CSI camera sitting in front of my robot. It's resolution is 640x480 with 160 degree HOV. I wanted to use the same camera in gazebo environment so I got all the camera properties from the hardware and setup a csi camera in gazebo world. However, the object from this camera looked extremely far comparing to the real world scenario. I was then tuning the parameters and realized that if I decrease the horizontal_hov values, the object in the camera frame would look a lot closer but the horizontal field of view decreases accordingly. Below is my camera setting in gazebo. Am I missing some camera properties? Also, I got the distortion values from the real camera, but by adding those numbers in gazebo didn't show any barrel effect like I saw in the hardware camera.

Any help is appreciated! I was trying to upload the images but unfortunately I don't have enough point to do so.
Even though this is a ROS plugin for Gazebo, I feel that you are asking about a specific behaviour of Gazebo you've observed. That would make this a question about Gazebo, which should be asked over at
answers.gazebosim.org
.If/when you post there, please post a comment here with a link to your new question, so we keep things connected.
thanks, yeah after I posted the question here and move on searching for a possible answer, I found someone asked gazebo question here and got moved to gazebosim.org. So I have already created the same post there. Then link is here https://answers.gazebosim.org/questio...
