We are developing a system to estimate the position of rice seedlings throughout a paddy field as part of a control system for a rice-duck farming robot. In this paper, we propose an inexpensive and easy method for mapping rice seedling positions in an entire paddy field using a video taken from the ground with a monocular camera, and verify the accuracy of rice seedling position estimation using this method. Although some problems were observed in the validation of the method, the estimated positions of rice seedlings generally reflected the actual arrangement of rice seedlings, indicating that the method was capable of estimating rice seedling positions.
