Robot positioning method and device and robot

The application provides a two-dimensional code based robot positioning method and device and a robot. The method comprises the following steps: firstly, acquiring an image corresponding to a currentposition of the robot; then, determining the current position of the robot according to a coordinate corresponding to a two-dimensional code in the current image, the area of the two-dimensional codein the image and/or position information of the two-dimensional code in the image. Therefore, the coordinate, the area and/or the position of the two-dimensional code in the image can be acquired according to the current position of the robot, so that the manner of positioning the robot is simplified, and the positioning precision and accuracy are improved. 本申请提出种基于二维码的机器人定位方法、装置及机器人，首先获取机器人当前所在位置对应的图像，进而根据当前图像中二维码对应的坐标、二维码在图像中的面积和/或二维码在图像中的位置信息，确定机器人当前的位置。由此，实现了根据机器人当前所在位置获取的图像中包括的二维码的坐标、二维码在图像中的面积和/或二维码在图像中的位置，即可确定机器人当前的位置，简化了机器人定位的方式、提高了定位精度和准确度。
