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 Seven-Segment Display, Dot-Matrix Screen and Industrial-Display Recognition. Scope: Display digits, signs, decimal points, units and flicker states.
Display digits, signs, decimal points, units and flicker states
Cover minus signs, decimal points and refresh transitions; use multiframe agreement or synchronized capture to avoid magnitude errors.
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
DB/DB++ text detection → orientation and perspective correction → SVTR/CTC recognition or Tesseract → field validation
Detection and tracking → polygons, crossing, distance, time-to-collision, dwell and hysteresis rules → event state machine
Provide real text/code samples, character sets and field rules, degraded prints, item mappings, validation interfaces and handling rules for duplicate codes or unknown content.
Result schema, algorithm or processing configuration, example outputs and evaluation records for: Display digits, signs, decimal points, units and flicker states. 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.
Full-string accuracy; decimal-point misreads; refresh/flicker coverage
Measure exact-field correctness, rejection and false acceptance. Break results down by font, carrier, degradation and lighting, and reconcile outputs with business records.
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.
Recognition is not authenticity verification or quality certification. Low confidence and validation conflicts require rejection, review or rescanning.
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.
Display digits, signs, decimal points, units and flicker states. Deliverables: Result schema, algorithm or processing configuration, example outputs and evaluation records for: Display digits, signs, decimal points, units and flicker states. Software format and source-code scope are agreed in the contract.
Cover minus signs, decimal points and refresh transitions; use multiframe agreement or synchronized capture to avoid magnitude errors.
Task-specific measures: Full-string accuracy; decimal-point misreads; refresh/flicker coverage. Measure exact-field correctness, rejection and false acceptance. Break results down by font, carrier, degradation and lighting, and reconcile outputs with business records.
After reviewing samples for display digits, signs, decimal points, units and flicker states, 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.
