New Tracking Algorithms, TLD, MedianFlow, and More!

kwatters's picture

So, in OpenCV 3.x there is a new opencv_tracking module that is exposed via JavaCV. 

This module contains 7 different implementation of object trackers.  There is a new "Tracker" filter that allows you to switch between any of these 7 tracking algorithms.  It should work pretty similar to how the lk tracking works in that it should publish the point that's being tracked.  Right now the filter only supports tracking a single point.  


Virtual Joysticks are Un-Breakable ! .. (mostly)

It took "too" long, but I got virtual Joysticks working ! ...  
To be precise, any device (joysticks, gamepads, keyboards, touchpads, .. etc) which the Joystick service can see can now be "virtualized".

Ok, so what the hell does that mean ? :)


Mesh Networking the LIDAR elements together ESP8266 <> ESP32

One step further in attempt to make a wireless system between the base rover station and the spinning Laser module.

 

In a Nutshell :-


Love Robo and MRL

For the past few months, Robo has been getting all my attention.  My wife and kids had to take a back seat while I made Robo strong, smart, and handsome.  I know he is not much of an Android yet, but MRL provides many features out of the box which are so neat!  For instance, the vision powers up, the wksr comes up with programAB, and then the servos power up.


MotorControl and MotorController - Range Mapping, Min Max, Input Output

GroG's picture

One of challenges with the old mapper was what to do when setting new values of min & max.
In the above diagram we see a range established by a min & max. 

e.g.  mapper = new Mapper(-1, 1, -1, 1)  

min & max input will be -1 & 1  .. min & max output will be -1 & 1

Current State of R0B-3

Hi I wanted to do this a long time ago and would wish that i would be more complete but I think I can still show what I have been doing with my robot.

Here is a photo of its current state (right arm broke and repair is in progress):

 


Stepper Motor Rover + HomeBrew Lidar

Thought it may be of interest to document a rover platform using Stepper Motors as drive linked to an ESP32 sporting a Web gui to control movement and display Sensor data.


Raspberry 3 plus cam for inmoov with mrl

Maybe a bit confusing but I was thinking about the following.

I am going to do a live build of an inmoov during the maker faire in Eindhoven, end of September 2018.
