Project 136: Thermal Imager Project Update 12: Interpolation
I have finished my interpolation code. The resolution has increased, but not to the extent that I had hoped. I am noticing increased definition in the image, which is proof of concept at least. I think in general the image quality is good enough now, I don’t think I need to look into any more […]
Project 136: Thermal Imager Project Update 11: False Colour Mapping 2
While implementing Interpolation, the next step in this project, I realised that the function I was using to convert the temperature values was not working correctly. Instead of returning smooth colour values between Red, Green, or Blue, it was returning EITHER Red, Green, or Blue. This was resulting in a very poor quality image. I […]
Raspberry Pi 2
I have just finished setting up my Raspberry Pi Single Board Computer. I am actually posting this from the PI itself. Well, technically, from a VNC connection to the PI. So far, I am finding it amazingly fast, feature rich, and easy to use. It really is a fully fledged computer which could fit into […]
Project 136: Thermal Imager Project Update 10: False Colour Mapping
I have successfully implemented the heat map, or false colour map. The quality of the resulting image isn’t fantastic, but it is quite good. I am confident that with proper post processing, such as interpolating, smoothing, etc, I can increase the quality even more. I implemented the heatmap by first converting the temperature information […]
Project 136: Thermal Imager Project Update 9: FLIR Lepton + Arduino Due: Success!
I have succeeded in interfacing with the Flir Lepton using the Arduino Due! I can now capture images from it. I actually had implemented code that was almost working (that I obtained from the Flir Dev Kit’s Google Group). But I could not understand it’s output values, so I decided to write a test program […]
Project 136: Thermal Imager Project Update 8: FLIR Lepton + Raspberry Pi 2
It may not be possible to use an Arduino device with the Lepton. Even the ARM based Arduinos, such as the Due, may not be powerful enough to properly read data from the Thermal Imaging Camera. The reason for this is that the Lepton will go “out of sync” if the data is not read […]
P-152: Virtual World Concept Update 51: Chunked Levels of Detail Using Quad Trees Part 19
This is a preliminary test of the optimised Quad Tree parsing system. The theory seems to be working ok, the terrain is being rendered more of less correctly. There are some issues with gaps in the terrain, however. I believe these are to do with the the view distance of the terrain. Sometimes a player […]
Project 136: Thermal Imager Project Update 7: FLIR Lepton + Arduino Due Integration Part 2
I have made some progress with the integration of the Lepton Module wth the Arduino Due. I found out that I was wiring Sda and Scl to the wrong pins of the Due board, I should have had them wired to Pinds 20 and 21, and I was wiring them to the “SCL1” and “SDA1” […]
