A positioning method for unmanned aerial vehicle is disclosed. A first photo and a second photo of a predetermined form are first obtained, a first color card image of a color card is recognized from the first photo, and a second color card image of the same color card is recognized from the second photo, wherein the predetermined form includes a number of color cards. A first geometric center point coordinate and a first barycentric point coordinate of the first color card image are calculated. A reference line on the color card is obtained by mapping the first geometric center point coordinate and the first barycentric point coordinate to the color card, and a rotation angle of the UAV based on the reference line is obtained. A positioning method to get the flight speed for the UAV and a positioning device is also disclosed.
