Stereo depth estimation
Stereo calibration and rectification → BM, SGBM or RAFT-Stereo → consistency checks and hole handling
JIVISION offers project development and technical assessment for Road Rut, Pothole Depth and 3D Pavement-Topography Measurement. Scope: Rut depth, pothole volume, road cross-sections and coordinates.
Rut depth, pothole volume, road cross-sections and coordinates
Vehicle vibration, water and occlusion affect depth; record unmeasurable areas and align results with positioning and distance.
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.
Stereo calibration and rectification → BM, SGBM or RAFT-Stereo → consistency checks and hole handling
Steger/Hessian laser extraction or phase/Gray-code decoding → phase unwrapping where applicable → triangulation
Voxel sampling, normals and FPFH → RANSAC or TEASER++ initialization → ICP/GICP/NDT refinement → geometric analysis
Orthorectification and registration → high-resolution tiling → rotated-box, semantic or two-timepoint analysis → GIS output
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: Rut depth, pothole volume, road cross-sections and coordinates. 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.
Depth/volume error; coverage; geolocation error
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.
Rut depth, pothole volume, road cross-sections and coordinates. Deliverables: Result schema, algorithm or processing configuration, example outputs and evaluation records for: Rut depth, pothole volume, road cross-sections and coordinates. Software format and source-code scope are agreed in the contract.
Vehicle vibration, water and occlusion affect depth; record unmeasurable areas and align results with positioning and distance.
Task-specific measures: Depth/volume error; coverage; geolocation error. 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 rut depth, pothole volume, road cross-sections and coordinates, 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.
