Subpixel edges and geometric fitting
Sobel/Scharr/Canny edges → subpixel refinement → RANSAC line, circle or curve fitting → geometric calculation
JIVISION offers project development and technical assessment for Container Liquid Volume and Meniscus Measurement. Scope: Liquid level, meniscus, volume and foam state.
Liquid level, meniscus, volume and foam state
Define meniscus reading position, allowed tilt and temperature; volume conversion depends on container calibration.
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.
Sobel/Scharr/Canny edges → subpixel refinement → RANSAC line, circle or curve fitting → geometric calculation
U-Net, DeepLabV3+, SegFormer or Mask2Former → connected components and morphology → region measurements
Stereo calibration and rectification → BM, SGBM or RAFT-Stereo → consistency checks and hole handling
Provide drawings/datums, range and tolerances, traceable references, surface materials, working distance, camera arrangement, calibration conditions and cycle time.
Result schema, algorithm or processing configuration, example outputs and evaluation records for: Liquid level, meniscus, volume and foam state. 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.
Level/volume error; foam/clear-container failure rate
Distinguish resolution, absolute error and repeatability. Compare independent references across the working range, record calibration residuals and environmental/pose changes, and assess the measurement system where required.
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.
Agree targets, stations, inputs and responsibilities in a statement of work, separating required and excluded conditions.
Use representative samples to test critical risks, document feasibility/failures and scope the next-stage estimate.
Implement agreed functions and interfaces with configuration/change records; use offline replay before authorized device or site integration.
Retest against individual measures and hand over contracted artifacts with known limits; manage maintenance, expansion and changeovers as subsequent work packages.
Pixel resolution is not measurement accuracy. Include occlusion, reflections, vibration and thermal drift in the error budget; confirm statutory metrology obligations separately.
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.
Liquid level, meniscus, volume and foam state. Deliverables: Result schema, algorithm or processing configuration, example outputs and evaluation records for: Liquid level, meniscus, volume and foam state. Software format and source-code scope are agreed in the contract.
Define meniscus reading position, allowed tilt and temperature; volume conversion depends on container calibration.
Task-specific measures: Level/volume error; foam/clear-container failure rate. Distinguish resolution, absolute error and repeatability. Compare independent references across the working range, record calibration residuals and environmental/pose changes, and assess the measurement system where required.
After reviewing samples for liquid level, meniscus, volume and foam state, 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.
