Converting Focal Length from Pixels to Millimeters to use in Bentley Context Capture
The focal length field in ContextCapture requires a focal length in mm instead of pixels. To convert a known focal length in pixels to mm: F(mm) = F(pixels) * SensorWidth(mm) / ImageWidth (pixel). For an X4S, the image width in pixels is 5472. Context Capture indicates the sensor width is 13.2 mm, so the equation…
