Embodiment Construction
[0016] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0017] Such as figure 1 Shown: In order to reduce the cost of manual observation and reduce the difficulty of observation, it can automatically detect whether the sugarcane has entered the stem elongation stage and whether the corn has entered the jointing stage in real time from the image features, and the detection result has a high accuracy rate. The detection method of the present invention includes the following steps :
[0018] Step 1. Obtain the crop image of the complete growth period of sugarcane and the crop image of the complete growth period of corn, and preprocess the obtained crop image of the complete growth period of sugarcane and the crop image of the complete growth period of corn;
[0019] Specifically, a video camera or a camera installed in the field may be used to acquire crop images of sugarcane in a complete growth period and crop image...
