Camera types used on agrobots: – RGB cameras – extensively used in agricultural machine vision applications for fruit/plant detection, yield prediction, segmentation tasks, disease detection, ripeness detection, weed detection and insects detection – Hyperspectral, thermal, or ultrasonic cameras – typically provide better results than conventional RGB color images – Stereoscopic cameras – provides 3D plant structure information (dimension of crops (depth information, crop height, leaf shape, leaf area etc.)) Critical factor is the camera’s resolution, which should be high enough to capture the details of the scene especially in the cases of insect and disease detection.

Cameras for mines and tunnels are an essential element of security and safety monitoring. The mining sector presents a number of challenges, from low lighting to connectivity issues in remote areas. These surveillance cameras observe the many processes within the mine and are mostly installed in a permanent, overt manner, with portable covert cameras being used on a temporary basis. IR thermal imaging cameras are often used as they offer the ability to see in dark, foggy or dust filled environments where there are large trucks, cranes, robotics and other moving apparatus that present danger to humans.

Wireless Z-Traps are devices used to catch pests around the plants using pheromone lure. Pest count information is wirelessly passed along from up to 1 km away using a base station to the online cloud service. This information is used to study and determine where and how much pesticides will be required. Imagery sensors capture imagery data to identify the diseases in plants – RGB sensors – have three colour channels, i.e., red, green and blue, which can be used to perceive the biometric effect in the plants – fluorescence Imagery sensors – used to distinguish the photosynthetic activities in the plants – spectral sensors – capture images containing the spatial information of objects in multiple wavebands, used to analyse crops’ health and pest attack – thermal sensors – used to measure the water status in the plant by measuring the temperature Weather condition monitoring sensors, i.e., temperature, dew, humidity and wind speed, are used to monitor weather parameters to find a correlation between pest growth with weather
