Wrong picture resolution and definition

[Cvalderrama97]

Hi
I am working with Lepton 3.5 with a breakout board 2.0 on a Raspberry pi 4. I am trying to get thermal pictures but pylepton is not capturing the frames properly. I used the lepton3-dev, lepton3 and the lepton libraries and I have the same output every time. The output picture has a 80*60 pixel resolution and even if I change the code to make the image bigger it is not working. Also, there are weird horizontal lines and the picture is not well define, apparently I got the same picture even if I move the camera. I have been troubleshooting for a while and I could not make it work. I appreciate any comment or changes I can make in the code to solve my problem. Thanks!

Hi, the issue is the software expects a Lepton 2 module with 80x60, but you have a Lepton 3 with 160x120 resolution. There is a Lepton 3 fork to Pylepton. Have a look at that. I've not managed to get this to work with the breakout board 2, but I've not been able to put much time into it. One issue is the software is old (8 years for some parts) and quite a lot of the installation instructions are obsolete. You should be able to get the raspberrypi_video -tl 3 to run to show that the board is connected correctly. The -tl 3 option specifies the Lepton 3.
