A UAV remote controller is easy to mistake for a sophisticated pair of joysticks. In an industrial drone system, however, it can sit at the center of four different information paths: flight control, drone telemetry, live video and payload interaction.
More sensors do not automatically make a better UAV payload. A single-sensor camera can be the most efficient choice for a focused daytime task, while a carefully selected dual-sensor payload may solve a specific information gap with less weight and
A camera payload can meet every imaging requirement and still be the wrong choice for an UAV platform. If its weight shifts the center of gravity, its startup current exceeds the available power rail, its video cannot pass through the
A thermal imaging camera can reveal temperature distributions that are difficult—or even impossible—to detect in an ordinary image. A visible-light camera, meanwhile, can show equipment, structures and the surrounding environment in much finer detail. During a UAV mission, operators often
A UAV camera advertised with 160× zoom does not necessarily capture 160 times more usable detail. The number may combine optical magnification, switching between cameras, cropping and image processing—each with different implications for image quality. For an industrial inspection or
A UAV laser rangefinder can add an exact-looking distance value to a live camera view. But a value displayed to the nearest 0.1 meter is not automatically accurate to 0.1 meter, and a published 1,200-meter range does not mean every
Four thermal drone payloads can use the same 640 x 512 detector resolution and still produce very different coverage and pixels on target. The reason is that pixel pitch, focal length and field of view work as one optical system.
A thermal camera for drones is often compared by four headline specifications: resolution, pixel pitch, frame rate and field of view. These numbers are related, but they do not describe the same kind of performance. Reading one in isolation can
A thermal camera can reveal an unusual heat pattern, but it may not show enough visible detail to explain what produced it. For many inspection and civilian patrol missions, the more useful question is not whether a drone has thermal
