Determining the position of the camera in space

[Vadim_Makeev]

Dear colleagues!

I had a task to determine the angle of the camera in relation to the plane. There are 3 spheres on a plane at equal distances from each other. I have a complete set of LabVIEV and Vision. The task is next. According to the coordinates of 3 points on the 2D camera matrix, determine the angle and direction of the camera tilt, provided that the numbers of the balls are recognized. Thank you in advance!

Hi Vadim_Makeev, 

if I understand correctly what you trying to do is to detect the deviation of the camera from normal position, aren't you?

Also. I would link to know in which environment are you using LabVIEW or Vision Builder? What did you try before to solve the problem?

I think you should try to have a default value and continually compare it with different positions of camera.

Hi l.hovs! For development, I use both environments depending on the task. My question is mainly in the field of mathematics. With the help of image processing, I can determine: 1. The position of the centers of the spheres in a flat (matrix) coordinate system. 2. I can determine with good accuracy the diameters of the projections of the spheres.
The mathematics itself is needed for converting a flat image into 3D space coordinates

Hi Vadim_Makeev, 

I have found a LabVIEW code example how to convert the image into a 3D textured heightmap. 

Try to go through that article and replicate teh code in your side to see what will be the results.

Thank you! I will definitely look into this option!
