PhotoModeler is desktop close-range photogrammetry software from EOS Systems (Vancouver) that has been used for forensic measurement since 1993. SkyeBrowse is a cloud platform that converts standard video into complete 3D scene models using patented videogrammetry. One measures pre-selected points from calibrated photos. The other captures the entire scene and lets you measure anything after the fact.

Capture Input
PhotoModeler requires calibrated camera photos taken from multiple convergent angles. Before capture, the operator calibrates the camera using a coded calibration sheet. At the scene, coded targets are physically placed on surfaces to provide reference points. The operator photographs the scene from predetermined positions, then manually marks corresponding points across photo pairs in the software. Every measurement depends on this deliberate, multi-step capture and marking process. Miss a target placement or a photo angle, and you cannot recover the data after leaving the scene.
SkyeBrowse accepts any .MP4 or .MOV video from any device. Drone orbit, smartphone walkthrough, body-worn camera, 360-degree camera. No calibration sheets. No coded targets placed at the scene. No pre-planned photo positions. Universal Upload means the operator records a continuous video of the scene and uploads a single file. The platform builds a complete 3D model of everything captured, and measurements happen after the fact on any part of the model.
Processing Speed
PhotoModeler's workflow is operator-driven at every stage. After photo capture, the operator imports images, manually marks reference points and coded targets across photo pairs, and the software triangulates 3D coordinates. The Premium edition adds automated dense matching, but the core measurement workflow still involves manual point correspondence. A typical crash scene takes 30 minutes to several hours of desk work after the operator returns from the field.
SkyeBrowse processes in the cloud at a 1:1 ratio. Ten minutes of video returns a finished, measurable 3D model in roughly ten minutes. No manual point marking. No post-field desk work. No triangulation stage. For crash reconstructionists who currently spend hours at a desktop after every scene, SkyeBrowse returns those hours to the caseload.
Hardware Requirements
PhotoModeler runs on Windows desktop machines. While it does not demand the extreme GPU power of tools like RealityCapture, it still requires a dedicated desktop installation and local storage for projects. The operator must be at that specific machine to process data and take measurements. There is no cloud component and no web-based access.
SkyeBrowse requires a web browser and an internet connection. Processing runs in the cloud. Models are accessible from any device. An investigator can upload video from the field, review the model on a department laptop, and share it with prosecutors through a link. No desktop tethering. No local project files. The hardware requirement is the device the operator already carries.
Accuracy and Measurement
PhotoModeler produces measurements on individually marked points — but only under ideal conditions. Achieving its claimed millimeter-level precision requires a calibrated lens, well-distributed coded targets, multiple convergent angles, and an operator experienced enough to execute every step correctly. In real-world field conditions (poor lighting, rushed captures, untrained personnel, imperfect target placement), that theoretical precision routinely fails to materialize. The software reports residuals and precision estimates for each triangulated point, but those numbers are only as good as the setup. The deeper weakness: you can only measure features you anticipated needing at capture time. If you did not place a target on it or photograph it from the right angles, the measurement does not exist.
SkyeBrowse builds a complete 3D model of the entire scene and lets you measure anything within it after the fact. SkyeBrowse is survey grade without the need for GCPs. Premium Advanced delivers 0.1-inch accuracy at 16K resolution with AI moving object removal. Premium achieves approximately 0.25-inch accuracy at 8K resolution. Lite provides 2-6 inch accuracy for rapid reference. When paired with an RTK-equipped drone, these results are georeferenced with no ground control points, no coded targets, and no extra field setup. The critical advantage: measurements the investigator did not anticipate needing at capture time are still available because the entire scene geometry is preserved. No returning to a cleared intersection to measure something you missed.
Operator Training
PhotoModeler demands substantial operator investment. Users must master camera calibration procedures, coded target placement strategy, manual point correspondence across photo pairs, triangulation geometry, and error propagation analysis. Effective forensic use that survives cross-examination requires months of training and supervised casework. This training burden limits deployment to specialized reconstructionists, not patrol officers or general investigators.
SkyeBrowse trains operators in a single session. Record stable video with complete scene coverage. Upload. Review and measure. The platform handles calibration, alignment, meshing, and accuracy verification internally. An agency can train forty patrol officers to capture scenes in a day. Training forty officers on PhotoModeler would take months and produce forty frustrated officers who still prefer the old way.
Pricing
PhotoModeler Standard costs approximately $1,495 and Premium approximately $2,995 as perpetual licenses. The Scanner add-on runs approximately $995. Annual maintenance adds ongoing cost. These perpetual licenses make sense for dedicated crash reconstruction units with one or two specialists. They do not scale to agency-wide deployment where dozens of personnel need documentation capability.
SkyeBrowse uses a subscription model tiered by output quality. Every tier includes cloud processing, AWS GovCloud hosting, browser-based sharing, and 5-year guaranteed data retention. For agencies deploying documentation across all field personnel, the subscription avoids per-seat desktop licensing and eliminates the specialist bottleneck. Scene documentation drops from $360 (3 hours, 4 officers) to $25 (10 minutes, 1 operator).
Compliance and Data Security
PhotoModeler has no compliance infrastructure. Project files live on the operator's local Windows machine. CJIS compliance, FedRAMP alignment, evidence chain-of-custody controls, and secure sharing are entirely the agency's responsibility. For a tool used primarily in forensic contexts, this absence of built-in compliance is a significant gap.
SkyeBrowse is purpose-built for regulated evidentiary environments. AWS GovCloud (US) hosting with FedRAMP Moderate alignment. CJIS-compliant workflows with audit trails and controlled sharing. 5-year guaranteed data retention on Premium and Premium Advanced tiers. Exports in LAZ (forensic reconstruction software, CAD tools), GLB (interactive courtroom presentations), and GeoTIFF (GIS integration, spatial analysis). The evidence handling infrastructure is part of the platform.
Feature-by-Feature Comparison

The Bottom Line
SkyeBrowse represents what forensic photogrammetric measurement becomes when you remove the calibration sheets, the coded targets, the manual point marking, the months of training, and the limitation of measuring only what you planned to measure. With tiered accuracy from 0.1-inch on Premium Advanced to 2-6 inches on Lite, SkyeBrowse delivers consistent, survey-grade results without any of the operator dependency that PhotoModeler demands. PhotoModeler pioneered this category three decades ago, but its workflow has not kept pace. For crash reconstruction units, investigative teams, and any agency that needs complete scene documentation from field operators, SkyeBrowse captures more, measures better, trains faster, and delivers sooner.
