Developing 3D models of fossils found in Thailand using photogrammetry techniques

Abstract

This research project is funded by the Fossil Management Fund, Department of Mineral Resources, Thailand, for the year 2023.The objectives of this research were: 1) to create 3D models of fossils using photogrammetry techniques, 2) to evaluate the efficiency of photogrammetry techniques in creating 3D fossil models, and 3) to assess the satisfaction with AR books and AR applications featuring 3D fossil models. The population consisted of Prathomsuksa 5 students in the Pathum Thani Primary Educational Service Area. The sample included 182 primary school students from this area, selected through purposive sampling. The research tools included: 1) 3D models of fossils found in Thailand 2) an evaluation form for the efficiency of photogrammetry techniques in creating 3D fossil models, 3) an evaluation form for the quality of 3D fossil models created using photogrammetry techniques, and 4) an evaluation form for the satisfaction with AR books and AR applications featuring 3D fossil models. Data analysis was performed using frequency distribution, percentage, mean, and standard deviation. The research findings were as follows: 1) The efficiency of photogrammetry techniques in creating 3D fossil models was evaluated at 91.52%. 2) The quality evaluation of 3D fossil models created using photogrammetry techniques showed that the highest quality aspects were the completeness of the 3D model, the color accuracy of the model surface, the completeness of the model surface, and the clarity of the model surface, with a mean score of 4.67, indicating a high level of quality. Overall quality was also high, the average was 4.54. 3) The evaluation of student satisfaction with AR books and AR applications featuring 3D fossil models showed an overall, the average was 4.31, indicating a high level of satisfaction. The clarity of audiovisual media and the interest generated by the media, which stimulated interest in the content, had the highest the average was 4.59 and 4.40, respectively, indicating a very high level of satisfaction.
