Need help - Camear overlay line animation example



  • Hello Qt people,

    I am new to Qt and working on an industrial project with linux based HMI.

    One of the requirement is to do an overlay to the front camera view of machine.

    Like car's parking assistance lines are required to be shown on camera.
    Lines changes angles and shapes based on steering angle feedback.

    Can anybody guide on how to do this lines animation?

    I am attaching an image for reference.

    And see the video link below for line animation examples.
    at 0:55 there is this animation.

    Thank you in advance for the support.

    Thanks
    Hardik



  • There is no direct way of doing this. We need to use the Qt drawing principles like QPainter etc and draw it and overlay the camera view.
