例23：LCD1602显示

基于单目相机和激光测距仪, 文章提出从一幅图像中识别出非合作目标物体上的矩形面,并提取出 4 个顶点坐标的特征提取方法,为位姿的测量提供必要的信息 提出以激光点为参考, 距离激光点最近的 4 条边 界为矩形面边界的判定准则,并根据激光点到直线的垂足和边界端点约束排除干扰线段 该方法能有效地判 定出矩形面且顶点定位准确,在空间机器人视觉伺服控制半物理仿真系统上得到了验证。(An approach to identi fying the rectangular plane of the object w i thout markers and extracting i t s ape- xes which are needed for pose measurement from an image is proposed in this paper. A cri terion is put forw ard that the edges w hich have the minimum distances around the laser point are regarded as the edges of the rec- tangular plane, and the interferent ial lines are eliminated according to the pedal between the laser point and the edge and two endpoints of the edge. The validity of the method is verified by experiments performed on a sem- i physical simulation system for visua- l serving cont rol of space robot s.)

说明：  单片机上电以后LCD屏上显示欢迎回家， 先验证指纹再验证密码 ，同时验证成功开锁 指纹和密码分别可以验证3次 3次都错蜂鸣器响 ，按下manage键进入管理员模式 可以修改密码 删减指纹，指纹用开关量表示(After the microcontroller is powered on, the LCD screen shows welcome home. First verify the fingerprint and then verify the password. At the same time, verify the successful unlocking fingerprint and password can verify that the buzzer rings three times and three times respectively. Press the management key to enter the administrator mode to modify the password and delete the fingerprint. The fingerprint is expressed by the switch.)
