This post will cover the concepts of image processing to generate and display image disparity or depth of field. This topic has been covered in earlier posts in regards to anaglyph imaging and OpenCV disparity mapping. The purpose of this post is to expand on this topic by demonstrating some features and limitations. Let’s start by leaving flatland.

The suggestions online point to anti virus as the cause, with disabling the anti virus or adding exceptions as the workaround. Others recommend using Visual Studio instead of the Arduino IDE. This post will…
This post will cover some use cases of the ESP-32 Cam module in low or no light conditions. The software and hardware of the ESP-32 Cam module will modified for this purpose. Some additional hardware examples will be introduced as well. Lastly, the use of FFMpeg will be demonstrated to further enhance the images gathered from the ESP-32 cam module. What are some reasons for the ESP-32 Cam module to be used in low or no light environments? The more…
