Perception, from sensor to estimate

Technical articles and worked tutorials on sensor hardware, deep-learning mathematics, and navigation systems, connected as one perception pipeline.

Three pillars

Three domains, one pipeline

Hardware sensors

Cameras, IMUs, and lidar: what each sensor measures, its noise characteristics, and calibration.

Deep-learning math

Derivations behind neural networks, built step by step from foundational definitions.

Navigation systems

Localization, mapping, and state estimation architectures for autonomous platforms.

Our approach

Start with the measurement

Every article begins with what the sensor actually measures, then works outward through the filters, models, and assumptions that turn raw data into a state estimate. Tutorials make each step explicit, so you can see where an idea depends on the hardware.

Worked examples, explicit assumptions, and clear trade-offs, written for engineers who want the mental model as well as the equations.
