Perception-Coverage Assurance
A perception system does not simply see or fail to see. It turns signals from a particular sensor configuration into objects, free space, crop or animal state, terrain, machine state or confidence estimates under a limited set of scenes. Coverage assurance makes those evaluated conditions and failures visible.

HOW TO READ THIS PAGE
Visual explanationA diagram or operating scene makes the relationship visible.
Structured modelA flow, comparison, capability set, or boundary map organizes the idea.
Guided explanationOriginal prose connects the concept to its operating context.
01 / Overview
Perception evidence needs
a defined input space.
NIST assurance work focuses on measuring how test environments cover the large input spaces autonomous systems may encounter. Its robotics program also treats perception, mobility and safety performance as connected but distinct measurement problems.
Agricultural research shows machine vision integrated with robots for specific tasks. Research results support the stated task and conditions—not general recognition, safe navigation or production readiness in every field.
02 / Coverage chain
Trace from scene
to physical consequence.
01DEFINE / 01Name target and decisionPerson, animal, crop, obstacle, terrain, row, tool or machine state; required output, timing, range, uncertainty and downstream consumer
02VARY / 02Structure scene dimensionsGeometry, scale, position, motion, lighting, weather, dust, vegetation, occlusion, clutter, background, sensor condition and combinations
03TEST / 03Measure representative performanceDataset and scenario provenance, reference truth, errors, latency, confidence, blind regions, failures, subgroups, repeats and configuration
04RESPOND / 04Connect uncertainty to behaviorRestriction, speed or task limits from approved design, alert, stop, fallback, human review, event retention and change trigger
03 / Evidence layers
One metric cannot describe
the perception boundary.
LayerQuestionCommon gap
SensorWhat signals and geometry are physically available?Mount, contamination, vibration or blind-region change
DatasetWhich targets and scenes are represented?Missing rare, seasonal or combined conditions
Model outputWhich errors, latency and uncertainty occur?Headline average hides important failures
System behaviorWhat happens when perception is wrong or unknown?Detection score is treated as safety evidence
04 / Practice
Preserve failures
as first-class evidence.
Protect reference evidence
Keep annotation or measurement method, reviewer agreement, ambiguity, missing truth, exclusions and corrections attached to evaluation data.
Retain hard cases
Store false positives, misses, late outputs, uncertain states, sensor degradation, near misses and unclassified scenes for controlled review.
Trigger re-evaluation
Reassess after sensor, mount, optics, model, preprocessing, crop, site, season, task, speed, tool or operating-domain change.
05 / Boundaries
Coverage evidence is not
a safety certificate.
No metric threshold, test scenario, sensor layout or dataset size is prescribed.Qualified system teams must define decision-relevant evaluation for the exact task and consequence.
Laboratory, simulation and field evidence answer different questions.None alone establishes complete real-world performance or safe behavior.
Perception is only one layer of autonomy.Localization, planning, control, safeguards, supervision, cybersecurity, maintenance and recovery still require independent assurance.
