  • I use houghcirlce to capture ball on plate. It take 100ms to process and return position of ball. it is too long, isn't it? could you say to me the period of system? and what algorithm did you use to capture circle on the place.

  • @tranducthien1987 To be honest , I know notthing about hough circle you just said. BTW The way I use to capture the ball was using VB.Net timer to process on the picture every 15ms(the fastest that timer in VB could). Yet, The function provided in VB.Net to process on picture aren't fast enough. So I have to create my own routine which is use the method call "Lock-bits" to process the picture faster.

    By the way I'm curious about "Hough circle" you just mention. Any details?

  • Thank you.

    But If you could introducte some reference about project to me. I'll feel very happy

  • @tranducthien1987 I use this one as reference for implementing PID control into microcontroller

    @ x-simulator.de/wiki/Implementi­ng_PID_control_in_Microcontrol­ler

  • Your project run very well. I begin doing a project like this. Could you give some documents about this topic to me.

    Thanks

  • @tranducthien1987 Thankyou for interested in our project. But unfortunately, all documents I have are scripted in Thai language. Sorry that I can't help you with the documents.

see all

  • You can read on this website to know about HoughCircle:

    aishack.in/2010/03/circle-houg­h-transform/

  • Hough Circle is a function which is supported by Library OpenCV. You can search on internet. It takes about 40ms to detect. But when i preprocess image to convert RGB into HSV then choice range of color which i want to capture, it take approximately 100ms.
