I want to make a self driving (autonomous) wheelchair where I want to create a map for localisation of the wheelchair.
I do not want to use LIDAR as it is very expensive. Also, I do not mind if the map is not created dynamically. I want to create a virtual 3D map of my building along with a virtual wheelchair inside it.
Then, I want to use a machine learning technique as suggested by these videos:
Finally, I can apply the learnt model on my wheelchair. So, my questions are:
How can I create a virtual 3D map of my building?
Is there any other better technique I can use in making the autonomous wheelchair?
