PoseMetric vs Overlap Camera

Capture precise 3D positioning data for photogrammetry. PoseMetric logs GPS, altitude, orientation, and compass data, enhancing your photogrammetry workflow. Calibrate your reference point for unparalleled accuracy. This application addresses a critical gap for photographers using Mirrorless/DSLR cameras, which lack the comprehensive sensor data available on smartphones. By placing the smartphone atop the camera, users can capture essential orientation and sensor information. A unique feature of our app is its sophisticated calibration system. This allows users to precisely “reset” the orientation once the phone is positioned, ensuring accurate data capture. This calibration, implemented using robust numerical methods to overcome the inherent instability of Quaternions for small rotations, is a significant technical achievement. The primary use case is to enhance photogrammetry workflows. Leading photogrammetry software packages support CSV data import. Our app exports calibrated sensor data in this format, enabling seamless integration with image sets to dramatically improve 3D reconstruction accuracy. Technical notes: Altitude is shown as orthometric height, which is the height above the approximate mean sea level. Conversion is done with the Earth Gravitational Model 2008 (EGM 2008) geoid associated with the World Geodetic System 1984 (WGS84) standard. User Manual available on our website

The biggest heartbreak in photogrammetry (3D modeling): you get home, start processing on your computer, and find out the photo overlap (lap rate) was too low. The model falls apart, and you have to go all the way back to reshoot. Overlap Camera lets anyone try photogrammetry, 3D scanning, and fixed-point observation with nothing but the phone in your pocket. No special gear, no professional equipment, no complicated setup. It overlays your previous photo semi-transparently on the live capture screen and shows a real-time overlap rate (LAP%) powered by your phone's IMU sensor. Because you can see the overlap as you shoot, you keep enough overlap every time, so your models don't break and you don't have to reshoot. Just point, line up the overlay, and capture. It's that easy to get started. New: choose any photo in a project as the reference. The app keeps overlaying that one shot, so you can return weeks later and line up on the very first frame. Free trial: every feature is free for 30 days after you install the app. To keep using them after that, an auto-renewing monthly or yearly subscription is required.
