Like using old vacation photos to figure out how tall a building looked or how far apart people were standing, photogrammetry uses pictures or video to measure real-world distances, angles, speed, and positions. In legal and insurance cases, it is a method for turning images from a crash scene, surveillance footage, dashcams, or phone cameras into scaled measurements that help show what likely happened. Accident reconstruction experts use it to estimate vehicle paths, impact points, sight lines, skid distances, and whether a driver or pedestrian could have seen a hazard in time.

That matters because crash scenes change fast. Cars get moved, debris is cleared, and injuries may keep a person from documenting the scene right away. When good photos exist, photogrammetry can help fill in gaps and support or challenge a police report, witness statement, or insurer's version of events. On Oahu, that can be especially useful when the Honolulu Police Department investigates a serious collision but later disputes arise over speed, lane position, or fault.

For an injury claim, photogrammetry can strengthen proof of negligence, causation, and damages by giving objective measurements instead of guesswork. But the results are only as good as the images, camera angles, and assumptions used. A weak analysis can be attacked by the other side, while a strong one may help in settlement talks or at trial.
