COMPARATIVE STUDY OF ACCURACY OF THREE-DIMENSIONAL MODELS OBTAINED FROM CLOSE-RANGE PHOTOGRAMMETRY USING ACTION CAMERA AND COMPACT CAMERA

Abstract

By applying the lens distortion model proposed by [1] up to the K3 radial distortion coefficient level, this research study seeks to contrast the suitability of using action cameras versus compact cameras. The results indicate that the action camera achieved an accuracy level of ±8.7 centimeters, whereas the compact camera attained an accuracy level of ±0.2 centimeters. This significant difference in accuracy levels underscores the substantial disparity between the two types of cameras. The findings suggest that future research should focus on developing a more refined radial lens distortion model to enhance the correction level. Such advancements would enable action cameras to be utilized more effectively in engineering applications. Additionally, the study highlights that compact cameras can achieve very high accuracy, suggesting that with appropriate systematic error corrections, these cameras can yield valuable engineering results and can be applied in various practical scenarios.
