Issue on the ai-imu-dr with the compiling and running python main file. #67
Comments
Hello Edern Ollivier Those first few SyntaxWarnings can be explained via https://adamj.eu/tech/2020/01/21/why-does-python-3-8-syntaxwarning-for-is-literal/ |
Dear Scott, thank to you, I dont have made any progress with the Martin's program and I am using Linux Ubuntu to program in C. Best regards, Edern Ollivier. |
If you are not using Martin's program, what are you using? |
Dear Scott, I am using a simple Kalman filtering technique supported by an Aduino Due board and libraries in C++, please check the source in my github at "https://github.com/EdernOllivier/GeographicalRecalibrationDue", its payload is minimal to get the best values said to be optimal in the space of the geography and timed buffered of the IMU/GPS recalibration. Best regards, Edern Ollivier. |
Do you know of an alternative and/or competitor to Brossard's program. I still cannot get a hold of him. I need a (free) dead reckoning program that tales IMU accel + gyrp and GPS (lat,long and alt) by which to predict the path of a moving vehicle when it e.g. goes into a tunnel and GPS is no longer active? Does your program do the job? I am not using an Aduino Due Board. Mind you, I gather if we had the required inputs to your program, I'd be ok? Question: will your program still predict the path well enough when a vehicle enters tunnel and there is no more GPS? (GPS outage) |
I dont know an alternative for this program, maybe with a research center in France ? |
Actually the team of researchers of them has been doing a lot of maths for the fusion algorithm, and I am deeply impressed by the tool of the Lie Algebra. Maybe that something is going to be discovered soon. |
Dear Martin, I have been installing the software to run the EKF, I had several errors, which are :
