Current Camera Error Displays the total error that remains between the

placed screen coordinate points, the CamPoint helpers, and the camera position

after the final computation. The calculations involved in the camera match

are seldom perfect. A good error range is about 0 to 1.5.

Camera Match Helper Objects

Camera Match Helper

Create panel > Helpers > Camera Match (from drop-down list)

Create menu > Helpers > Camera Point

Camera Match helper objects (CamPoints) are used by the Camera Match

utility to reproduce in a camera the same settings (position, roll, and FOV)

that were used by a real-world camera to shoot a background image. This

allows you to view your scene from the same perspective as the background

image, which is a key step to mixing computer-generated and

photographically-generated images in a single composited shot.

Camera point objects are placed in the scene at locations that will be visible

in the background photograph. By comparing the X/Y/Z position of several

camera point objects to their analogous positions in a background image, the

Camera Match utility is able to determine the real-world camera’s settings,

and use these settings to either create a new camera or move/reset an existing

camera to match them.

CamPoint on page 5255 object type, choose CameraMatch from the

Object set list.
