Review Axis reference-map replacement separately from calibration reset

Bottom line: Choose the map operation deliberately before replacing a radar background. Preserve the distinction between retaining calibration parameters and proving that the replacement image still aligns with the radar’s actual scene.

Source fact: documented behavior

Axis’s Radar image describes replaceRadarImage as replacing an already calibrated reference image while keeping its related parameters.

The separate resetCalibration operation removes the current reference map and resets the associated reference-map parameters.

For replacement images, the documented supported formats are PNG and JPEG.

What the source does not establish

Do not infer correct alignment merely because calibration parameters survived. A replacement map must still represent the intended scene, scale and orientation. Keep a background-image change separate from redesigning detection zones or proving perimeter performance, and do not reset calibration as a routine substitute for the intended replacement operation.

Applicability questions

• Is the current reference map already calibrated?
• Should this change retain its parameters or deliberately start a new calibration?
• Does the approved replacement image represent the same intended scene geometry?
• Which known landmarks and permitted target observations will confirm alignment afterward?

DSE recommendation: controlled next steps

The following steps are DSE recommendations based on the cited source.

DSE recommends documenting the intended calibration disposition before selecting the supported reference-map operation.

1. Record the current map identity and relevant calibration information through supported read operations. Have the radar owner approve the replacement image and describe what changed. Distinguish a cosmetic image revision from a scene or geometry change. Preserve an authorized recovery copy or reference to the previous configuration before editing the installed map.
2. Choose the documented replacement workflow only when retaining the existing parameters is the approved intent. Confirm the file’s supported format and review its intended scale, orientation and landmark positions. Retain the actual operation response rather than treating the uploaded filename as success evidence. If the intended work requires new calibration, plan that separate supported process explicitly with the owner.
3. Compare the resulting view against known landmarks and an approved harmless target observation. Inspect the radar-to-map relationship through the normal operator workflow. If it disagrees with the scene, stop acceptance and investigate the image and calibration rather than moving a marker solely to make the display look plausible. Restore or recalibrate through the agreed procedure when required.

Verification and evidence

Retain the previous and replacement image identities, approved operation, parameter observations, sanitized response and permitted alignment evidence. Ask another reviewer to distinguish parameter retention from verified geometric agreement. Record any scene change that requires broader detection or zone acceptance separately.

Use a proposed desk case that requests a background refresh while accidentally selecting calibration reset. Require the reviewer to reject that operation before execution. This article reports no map replacement, verified radar position or completed detection-performance result.
