Arducam UC-625 with UC506

Hi, I have managed to get to the point where 1_test.py runs however after I select the mode [7], I have an error. I have connected the board onto Raspberry PI 4 4G and have set 180Mb of memory for the GPU. I have tested on raspistill and it worked fine. I have upgrade the firmware etc. on the Pi. Please can you help?

Please ensure you have installed all the additional repositories

Hi Bin, could you please post the link because, I found one on a blog which I followed and didn’t have much success with and and I then followed steps in a readme file with which i got further but not far enough to be able to run the 1_tests.py etc.

Is there a way to find what the missing files/repositories are?

Thank you in advance.

Hi Bin, please see below output of installing libraries i thought may have been missing.

Hi,

I have searched this error. This seems to be a coding problem instead of compiling error.I think your code is right.

Can you try to delete the old file and create a new file to retry?

 

Hi Bin, and thank you for your help.

 

I am only trying to run the example code from the arducam github repository in http://github.com/ArduCAM/MIPI_Camera/tree/master/RPI/stereo_depth_demo or even just the ./video file and it crashed.

This is not my own code. Do you mean I should delete and reinstall the MIPI repository from GitHub? I can do that no problem however please confirm this is what you would like me to try.

 

Thank you.

 

Hi,

Yes, you can try to delete and reinstall the MIPI_Camera library. If the problem is still exist, I will tell our engineer to check it.

 

Hi Bin,

Ok I deleted the folder and followed the steps to download the repository and compile the files and install and i was able to run ./video this time but i am still not able to run the demos in /stereo_depth_demo and I still get the error “mmal: Failed to fix lens shading, use default mode!”

The farthest I got was to be able to run “python 1_test.py” which displayed a dual screen image upside down and in green colour I have been able to test “1_test.py” in mode 7 through to 10 all were upside down and green in colour.

I cant run any of the other demos in the folder.

 

 

Ok I was able to run ./video before from the main RPI folder but i can not do that anymore it just closes after 1 frame.

It recognises my dual camera on the board UC506 as IMX219 (i am supposed to have dual 8Mpix cameras) but in the folder lens_shading_table I can not see a folder name IMX219. Only the following.

  1. ov5647

  2. imx298

  3. imx135

  4. ar1820

Hi,

We optimized the frame rate and Angle of 219. the lens shading table we create before is not suitable for it now. When I am free, I will recreate new lens shading table again.

 

Hi Bin,

Does that mean I can now test the camera until the lens shading table is created?

Hi Bin, good morning, when would the the lens shading table for IMX219 be available? My understanding is that without it cant test all the demo casses.

 

 

Hi,

I am too busy to create the lens shading table recently. Tomorrow I will spare some time to help you fix it.

It does not affect your to test various modes.

Hi Bin, Thank you very much for making that table.

So do you think i should be able to run the stereo depth demos without updated lens shading table?

I have tested 1_test.py again just now and again the image is upside down and green, I can only run mode 7 to 10 anything higher I get “Null Pointer Access”. In addition i am not able to run 2_chess_cycle.py and get the error below still.

Hi,

Yes, the lens shading just improving the dark Angle of the lens. You can try it without lens shading.

ValueError: NULL pointer access means it does not receive image from the sensor. There is nothing to do with the lens shading. Do you use our new libarducam_mipicamera.so ?

Recently, I have updated our libarducam_mipicamera.so. You can try to download our new lib to try. Notice to run make install to install the new lib.

What’s more, you can use arducamstill demo to test each mode firstly to ensure each mode can work normally.

https://github.com/ArduCAM/MIPI_Camera/blob/master/RPI/arducamstill.c

just run ./arducamstill -t 0 -m [mode]

Let me know if you need more help.

 

Thanks, Bin. I got most of the above to work. I am still dealing with a green screen when i run all the demo python scripts which seems to be affecting the calibration? I can tune the color and brightness of the screen using ./arducamstill -t 0 but then when i run python 1_test.py it shows up as green. I found your post here which seems like a potential solution:

https://www.arducam.com/forums/search/green/

However which exact file (name and file extension) do I need to update in order to do that. If it’s a .c file, how would you compile the c code using the command line?

when i run the 4_calibration.py file, it ignores all of my 30 images.

I look forward to hearing from you.

Best,

Tom

Thanks, Bin. I am still getting a green screen when I run python 1_test.py. I played with ./arducamstill -t 0 and was able to tune the color brightness and focus. However, when I run 1_test.py, it goes back to green.

I saw in another post that you changed the register values or the set mode? Which exact file would you make those changes to and if the file is a c file, do you need to compile after? How would you compile that file on the command line?

Also, when i run 4_calibration.py, it ignores all 30 of my images. I am assuming because too dark and green?

Best,

Tom

Hi Bin,

I have just downloaded and compiled the github repository as per your instructions and I still get the results below. Is the hardware faulty?
