Liquid Leak, Splash and Floor-Pooling Detection
JIVISION offers project development and technical assessment for Liquid Leak, Splash and Floor-Pooling Detection. Scope: Visible leaks/splashes, pooled-liquid areas, spreading and persistence.
Scope and project-specific requirements
Task / output
Visible leaks/splashes, pooled-liquid areas, spreading and persistence
Critical decision conditions
Include reflective floors, wash water and shadows; RGB images alone cannot identify chemical composition or corrosive hazards.
Candidate technical approach
These are candidate implementation paths. Establish a baseline on real samples, then select or combine methods for imaging, speed and deployment constraints. Model names do not imply measured project results.
Region segmentation and quantification
U-Net, DeepLabV3+, SegFormer or Mask2Former → connected components and morphology → region measurements
Object tracking and trajectory management
Object detection → ByteTrack, OC-SORT, BoT-SORT or Norfair association → Kalman filtering and track management
Spatial rules and event state machines
Detection and tracking → polygons, crossing, distance, time-to-collision, dwell and hysteresis rules → event state machine
Inputs for assessment
Provide camera layouts, authorized video, target sizes, day/night samples, region/event definitions, concurrent streams, alert-review workflows and retention periods.
Deliverables and interface agreement
Result schema, algorithm or processing configuration, example outputs and evaluation records for: Visible leaks/splashes, pooled-liquid areas, spreading and persistence. Software format and source-code scope are agreed in the contract.
Specify input formats, output fields, coordinates/units, error states, versions and invocation methods. Define review and failure handling. The statement of work determines the exact scope of source code, executables, model files or analysis reports.
Acceptance method and measures
Task-specific acceptance measures
Leak recall; minimum area; false calls per day; discovery time
Evaluate events rather than only frames: misses, false alerts per hour, duration error, alert latency and recovery after occlusion. Include empty scenes and hard negatives.
These are measures to agree and test, not achieved-performance claims. Freeze samples, reference truth, thresholds and hardware/software versions before acceptance; report subgroup results and failures, identifying under-sampled conditions as uncovered.
Implementation and procurement stages
Define scope
Agree targets, stations, inputs and responsibilities in a statement of work, separating required and excluded conditions.
Sample validation
Use representative samples to test critical risks, document feasibility/failures and scope the next-stage estimate.
Development and integration
Implement agreed functions and interfaces with configuration/change records; use offline replay before authorized device or site integration.
Acceptance and handover
Retest against individual measures and hand over contracted artifacts with known limits; manage maintenance, expansion and changeovers as subsequent work packages.
Scope limits and licensing
Use data minimization, anonymization and access controls as needed. Do not infer sensitive traits, emotions or medical status from appearance; review alerts and retain existing safety measures.
Candidate technologies are not license clearance. Check code, model weights, training data and dependency versions separately. Replace, license or exclude components unsuitable for the intended commercial delivery. Customer data is not used for public training by default.
Project FAQs
What does this service produce?
Visible leaks/splashes, pooled-liquid areas, spreading and persistence. Deliverables: Result schema, algorithm or processing configuration, example outputs and evaluation records for: Visible leaks/splashes, pooled-liquid areas, spreading and persistence. Software format and source-code scope are agreed in the contract.
What needs to be confirmed first?
Include reflective floors, wash water and shadows; RGB images alone cannot identify chemical composition or corrosive hazards.
How is acceptance defined beyond a demonstration?
Task-specific measures: Leak recall; minimum area; false calls per day; discovery time. Evaluate events rather than only frames: misses, false alerts per hour, duration error, alert latency and recovery after occlusion. Include empty scenes and hard negatives.
How are cost and schedule assessed?
After reviewing samples for visible leaks/splashes, pooled-liquid areas, spreading and persistence, equipment conditions and interfaces, scope validation, development, deployment and acceptance separately. Data coverage, site changes and delivery rights affect the estimate; no fixed performance or schedule is promised before assessment.
