New bug :(

Hi Claude,

I’ve not investigated yet, but I note you are in the process of changing the time format. Well, it breaks it 😦

I’ve roll my Production instances to the previous version, but wanted to let you know ASAP, so sorry for the ‘raw’ bug report.

Cheers,

Richie

This is used to name sub folders and did not previously have a problem I checked my speed camera and it changed directories fine. Will do some more testing to see if I can duplicate error.

Thanks Claude - I’ll give it a try on my new rpi’s 😉

Loving the work - and you are teaching me python too - thanks!

Cheers,

Richie

Hi Richie

I have updated speed-cam.py to version 9.3. This fixes some bugs and adds some better error messaging.

Fixed Fatal error when imagesSubDirMaxHours is greater than 0. Note Normally you would set subdir creation for max files or elapsed hours but you could set both. If you set by max hours and duration is short you may may get empty folders. I still recommend using max files to create subfolders rather than elapsed time.

Also fixed DeleteOldFiles function to give better error message. Sometimes you might delete files in the media/images folder and break the symlink in recent folder. This creates an error when globbing the recent folder to delete oldest symlink file since some symlinks do not point to a file. The fix is to delete all files in the media/recent folder. This should fix the problem and new recent symlinks will be created that correctly point to existing image files.

Give this version a try and let me know if you have any issues.

You can upgrade by running the menubox.sh UPGRADE menu pick

Thanks for your feedback Regards Claude …

I accept github project push/merge requests from contributors after reviewing changes to make sure they are OK. Anyone can clone the project and send updates to the project. Some dev’s have translated speed-cam to javascript. One user rewrote speed cam project in a more package cross platform format. These were separate forks. Please note I have been retired for approx 13 years and just do this as a hobby. Speed cam started as a demo and gradually got more complex to handle python2 and 3. Use webcam, better logging and error checking Etc Claude …

Hi Claude,

Thank you for the kind words. Yes, we are processing night data at the moment. sqlite3 is great, and works really well. There are 3 cameras active in the village the moment, and I am building out 3 more at the moment, so we should have reasonable coverage soon.

On the identification part, yes, I would love to do that. I noted that the webpage tries to guess at the moment, so I am thinking about storing that info as an initial cut once I figure out where to get it from. Also, It turns out that a few folks round here are dev’s, so we might get more bells and whistles added in future. Which makes me wonder, I don’t really want to fork your project and work on it without you, so what do you think about adding more contributors? I fully understand if you say no, and of course, if that is the case you are welcome to work on the fork of course!

Look forward to hearing from you.

Cheers,

Richie

Thanks for the link to your project. Keep up the good work. I will check occasionally to see how your data looks. My camera has run for several years. That is why I added sqlite3. My Data is not always vehicles, since it can pick up birds flying by, me cutting the grass, pedestrians walking on our side of the street, etc. I have thought of adding post processing to have opencv recognize catalog objects. It would be nice to have a breakdown of vehicle, types like cars, trucks, buses, motorcycle, bicycle, backhoes, garbage trucks Etc). BTW are you processing night data?

btw - i am in the process of transferring the data from my lab up, so please excuse the lack of data!
