estworldpose giving different answers on each run.

I have the a setero camera calibration file and am using the first image from the set of images to define a target line for my application. To find this orientation I am using the estworldpose function (I have attached the calibration file, the image points and the world points in use). Each run with the function gives different rotation matrix and translation values, (I can see the error in tranlation clearly). For refrence: translation should be roughly [100,50,-1900].
Are the different values because of one/all of these reasons?:
- An image used in calibration should not be used
- The ransac method method is not working because the world points I gave are planar (I want to use the checkerboard to define the target line)
If there is another reason can you explain it please.
Thank you.

estworldpose is a RANSAC-based method. You may want to set the random seed before running the function to get persistent results.
