The image position estimation module ZEN-VOMD-001 can acquire information such as the movement position simply by attaching a camera to a moving object. In addition, it is designed to reduce the error in the stopped state because it automatically judges whether it is stopped. When building a mobile robot, the coordinates of the robot are measured by measuring encoders attached to the wheels and markers attached to the robot. However, in the case of encoder measurement, there are problems such as slip and inner ring difference, and in the case of measurement with markers, problems such as the measurement range limit due to the number of cameras installed and discontinuous measurement due to occlusion due to surrounding objects.
