Programmed to execute tasks with the utmost precision and accuracy. Also known as precision farming, These robots eliminate human errors commonly associated with manual farming practices. From plant spacing to pesticide application, and beyond, robots ensure uniformity and consistency. This eventually leads to improved crop health and reduced wastage.
Precise Use of Resources
These robots also enable the precise use of water, fertilizer, pesticides, and other agricultural inputs, contributing to resource conservation. Moreover, robots minimize chemical inputs and reduce the risk of overuse or pollution by employing targeted application techniques based on data-driven insights, promoting eco-friendly agricultural practices.
Key Features Required for Cameras Used in Agricultural Robots
When selecting cameras for agricultural robots, several key features are essential to ensure optimal performance in varying conditions and specific tasks. The exact requirements may vary depending on the application. But the following features are commonly sought after:
High Resolution
High-resolution cameras are essential for capturing detailed images of crops, soil conditions, and pests. Higher resolution allows for clearer visualization of small details, enabling vision algorithms to carry out more accurate analysis, such as identifying crop health issues or detecting weeds.
High Dynamic Range
Agricultural environments often experience varying lighting conditions, from bright sunlight to dull overcast conditions. HDR cameras are capable of capturing images with a wide range of brightness levels, ensuring that details are preserved in both well-lit and shadowed areas. This feature is particularly important for accurate image interpretation and analysis.
Global Shutter
In scenarios where fast-moving objects need to be captured without motion blur, such as when imaging crops from a moving robot, cameras with global shutter functionality are essential. A global shutter in a camera ensures that all pixels are exposed simultaneously. This prevents distortion and ensures that the images are clear and sharp, even in high-speed applications.
