DIY AI Camera with ESP32-CAM That Analyzes and Describes Images DIY enthusiasts have made an AI camera that, instead of displaying images, reads the images and gives a description about them. For doing so, it sends the image to an AI, which then generates a text description of the scene. The description is displayed on a small OLED screen, giving users a fresh and creative way to "see" the world through AI’s perspective. The camera comes with multiple… |
