- 104 - It is not impossible however to foresee a level of development where a hybrid approach such as Thealasermetry is made al most redundant by improvements in the laser scanner package. It should be technically possible to achieve the following im provements: A) Upgrade the laser scanner’s level of precision at both data collection and restitution stages in order to produce accu rate lines and outlines; B) Up grade the laser scanner’s built-in digital camera to a high-resolution capability minimum 5 megapixels but ide ally 12,000 x 16,000 pixels; C) Build-in u theodolite total station function into the same box as the laser scanner rendering it a hybrid machine - and thus integrating the hybrid approach into the very de sign of the system; D) Developing targets which can be used by all three sys tems; E) Develop the post-acquisition restitution software with a more refined algorithm capable of handling large ob jects/sites consisting of over 100 million points while at the same time having an advanced pattem/form- recognition function (possibly using an extensive library) which would permit automatic identification of fprms at the consolidation stage. These developments should be technically (and economically) within reach over the next 5-10 years and would result in a sin gle portable package which would enable the laser scanner cum high-reolution camera cum theodolite to supplant photogram- metry in most but not necessarily all cases of on-site documen tation in the cultural heritage sector. Acknowledgements The authors wish to thank all staff within MCR’s Documenta tion Division without whose hard work and commitment the results published in this paper would not have been possible. Anastasia Anastasi, Ivann Borg and Marcia Young of 3DID were instrumental in devising parts of new solutions Likewise MCR’s partners and service providers, MENSI of France and Photarc of the UK collaborated extensively in the work which led to the successful integration of laser scanning data with digital photogrammetry vector outlines References 'j.-A.
