8. An electronic device comprising:
a processor; and
a storage device storing a plurality of instructions, which when executed by the processor, cause the processor to:
obtain a color image and a depth image of a plant to be detected;
obtain a target image by performing a mapping processing on the color image and the depth image;
detect the color image by using a pre-trained mobilenet-ssd network, and obtain a detection box comprising the plant to be detected;
extract a target contour of the plant to be detected from the detection box;
determine a depth value of each of pixel points in the target contour according to the target image; and
perform a denoising processing on depth values of the pixel points, obtain target depth values, and determine a height of the plant to be detected according to the target depth values.
