If the scene still doesn't fully match, you can continue modifying the parameters for each sensor image until you get a good fit of the scene in the Stitching view. | If the scene still doesn't fully match, you can continue modifying the parameters for each sensor image until you get a good fit of the scene in the Stitching view. | ||
You can use the transparency and lock features to help you match the scene. | |||
The transparency feature allows transparent images to match objects between the projections. The lock feature locks the image movement for an easier projection tune. | |||
