Claim Text:
1. A method for determining orientation of a geodetic instrument, said method comprising: causing at least one imaging module of the geodetic instrument to capture at least one image; producing an image representation of said at least one image; detecting in the image representation, identifying means of a target and a measuring instrument; processing the image representation for determining angular information of at least one of the measuring instrument and the target with respect to at least one axis; receiving signals indicating distances and angles from the measuring instrument to the geodetic instrument and to the target; and estimating orientation of the geodetic instrument relative to a coordinate system based on said angles and distances to at least one of the measuring instrument and the target, respectively, in relation to the geodetic instrument, and the angular information.
