Open cv and the jetson nano pi cam
I'm just a little behind on that one as I just got to the building of the servo mechanism when I got side tracked. Just not enough hours in the day, or enough hands either! ?
Thanks I must have gone code blind when I'm gazing right at the problem and can't see it a lot like when I look in the mirror lol and now it says I didn't define (dspW) in the string this isn't like the cut and dried arduino way #define what is define in python? Thanks .??
Thanks I'm going to try it fingers crossed ................Boom just kidding I didn't try it yet.but I'm going to thanks??
in the horrible long string some variables are concatenated in. The variable dspW has not been defined so it knows not what to do. This is probably because the string in the lesson 11 notes is shown as dispW ? .
I think this is code from the old and now unsupported python 2. This string could look far mor readable in the latest python 3.7 using f strings. Python 2 is fading fast away
I actually ended up with 4.1.1 in open CV and 3.6.8 in the terminal by using / will this make it work? Seems like if I can't get the camera working the nano turns into a no no lol. I'm new to python so it might take me some time.
I dont know anything about opencv, although it is on my to-do list. Just make sure you are using the opencv version that is compatible with the python version you are using. (no idea what you mean by 3.6.8 in the terminal - though I could presume you mean you are using python version 3.6.8). As with any programming language it would be worth taking a short time out to get up to speed with the basics. I suggest a few hours watching corey schafter videos will make you feel much more comfortable with python. watch
And its \ not / ?
It doesn't work with either one disp or dsp I tried both this is what it says
That's a terrible camera image 🙂
Have you tried the: <print screen> keyboard button, or even <ALT-Print Screen button> for active window capture?
I would have had to learn the basics to get to this point !and yes it means 3.6.8 in the terminal and 4.1.1 in Open cv python versions but this updated version does not install 3.3.1 using the method in the tutorials but its OK it doesn't matter I got a strait answer on hackster io .
@duce-robo - good the hear you have got the answers you were looking for. As openCV is on my list I had a quick peruse at some of P Mc's video's. As AI is not an interest to me I wont be pursuing his tutorial to get into openCV and I found I did not get along with his style of presentation. Each to his own of course but it highlights to me just how good Bill of dronebots is. And from P Mc's video in this series that introduces python I can confirm that he is using python version 3.6.8. I see from your screenshot you appear to be using PlatformIO as your IDE then don't forget the debugging and REPL facilities to assist when you hit those error messages. Have fun.
Yes open CV is something I think I'm going to just have to nibble on slowly I tend to dive in too fast and I do thank everyone for their help .I'm not much of a code writer I think even when I get a better understanding of python and open CV I still won't be able to come up with any of my own sketches.but who knows maybe??
