Re: Get Vision Sensor intrinsic and extrinsic parameters

Hello, 1. How do I find the horizontal and vertical FOV? Can I use this formula to calculate the focal length in pixels? ''you have a right-angle triangle, with half the FOV as one of the angles (a), and half your image size as the opposite side (A). To calculate the focal length F, use tan(a) = A/F...

Get Vision Sensor intrinsic and extrinsic parameters

I have a scene with some aruco markers on it, I wish to estimate its pose for which vision_sensors intrinsic and extrinsic parameters are required. I can get focal distance and resolution of the sensor from object properties but can't use them directly since focal distance needs to be in 'pixel' (th...

B0 Remote API: destroyed all streaming functions for client after detection of inactivity

I am creating a python script that uses BlueZero Remote API to start the simulator and stream the vision sensor image, I am on windows and was successful in getting the image but after about 30sec of simulation time the script hangs and this message appears in the simulator: "B0 Remote API: des...
