毕 业 设 计 中 文 摘 要 近些年无人机逐渐出现在很多领域，应用于很多方面，越来越频繁的出现在大 众的视野中，无人机快递，无人机外卖，无人机航拍，甚至火灾中帮助高层受灾住 户逃生的高空坠落兜网概念无人机，生活中将已越来越不可避免的与无人机接触。 正是由于无人机的越来越生活化，在无人机执行任务中，周边环境将日趋复杂，这 时就需要无人机增加避障功能，并且越来越智能化，不仅要保障机体不受损，更要 保障他人的人身安全。所以，智能避障已经成为无人机研究的热点问题之一。这个 避障技术是由激光传感器实现的，激光传感器内部的激光发射器发射激光，接收器 接收激光，根据接收发射时间差算出距离，无人机将从传感器接收的距离数据整合 后发送至PID控制器，由PID控制每一个电机的转速来躲避障碍物。 关键词 无人机 避障 飞控 激光测距 毕 业 设 计 外 文 摘 要 Title Design of UAV Obstacle Avoidance Technology Based on Single Chip Microcomputer Abstract In recent years, unmanned aerial vehicles (UAVs) have gradually appeared in ma ny fields and applied in many fields. More and more frequent UAVs appear in t he publics vision, such as UAV express delivery, UAV takeout, UAV aerial phot ography, and even the concept of High-altitude Falling net UAV, which helps hi gh-level victims escape in the fire. It will be more and more inevitable to contac t with UAVs in life. It is precisely because of the more and more life-oriented UAV, in the UAV mission, the surrounding environment will become more and more complex. At this time, UAV needs to increase the obstacle avoidance functi on and become more intelligent, not only to protect the body from damage, but also to ensure the personal safety of others. Therefore, intelligent obstacle avoida nce has become one of the hot issues in UAV research. The obstacle avoidance technology is realized by a laser sensor. The laser emitter inside the laser sensor transmits the laser and the receiver receives the
