Summary: | The invention discloses a plant height measuring method, which belongs to the technical field of digital agriculture and comprises the following steps of: S1, preparing a ruler with a red area at the top end; s2, placing a scale behind the plant, and ensuring that the red area is not shielded by the plant; s3, obtaining a target image containing the plant and the scale through shooting; s4, identifying a red area of the scale in the target image; s5, setting a pixel transverse range A of the scale in the target image; s6, calculating the pixel position difference of the red area; s7, calculating the real length of a single pixel; s8, searching a first green point as a plant vertex in the range A; s9, calculating the pixel position difference between the item end of the red region of the scale and the vertex of the plant in the target image; s10, calculating the actual height of the scale above the vertex of the plant; and S11, calculating the actual height of the plant. The method is suitable for a field obse |
