摘　　要：以杂交水稻秧苗位置检测为目标,结合农田生长环境,要求学生设计一款基于红外检测的探测装置。该装置采用抗干扰对射型红外传感器,并创新性地增加了人造纤维丝毛刷结构,通过接触式感应原理增强了探测效果,提升了对细小农作物的探测能力。该课程实验包括硬件设计和软件算法设计,并通过实验测试验证了探测装置的有效性。Taking the position detection of hybrid rice seedlings as the target and combining with the farmland growth environment, students are required to devise a detection device based on infrared detection. The device adopts anti interference infrared sensor, and innovatively uses the structure of fiber of rayon brush. As a result, the detection effect is enhanced through the contact induction principle, and the detection ability for small crops is improved. The course includes hardware design and software algorithm design, and the effectiveness of the detection device is verified through experimental tests.
