Abstract
Apparatus and methods useful in surveying to provide information rich models. In particular, information not readily or possibly provided by conventional survey techniques can be provided. In some versions targets provide reference for baseline positioning or improving position information otherwise acquired. Scanning may be carried out in multiple locations and merged to form a single image. Machine mounted and hand mounted scanning apparatus is disclosed.
Claims21
A target for use in combined radar and photographic scanning, the target comprising:
- a support;
- a generally symmetrical structure mounted on the support having the same appearance to a photographic scanning device from different vantages;
- a radar reflector mounted on the support in a predetermined position with respect to the generally symmetrical structure whereby the target can be correlated between radar and photographic images.
