The free-form surface feature recognition method may be a feature recognition method based on boundary matching or a feature recognition method based on stereo decomposition.
可以理解，在本申请中的舵机结构，是由直流电机、变速齿轮组、可调电位器和控制电路板组成的一套自动控制***。通过发送信 号，指定输出轴旋转角度。舵机一般而言都有最大旋转角度(比如180度)。控制信号由接收机的通道进入信号调制芯片，获得直流偏置电压。它内部有一个基准电路，产生周期为20ms，宽度为1.5ms的基准信号，将获得的直流偏置电压与电位器的电压比较，获得电压差输出。最后，电压差的正负输出到电机驱动芯片决定电机的正反转。当电机转速一定时，通过级联减速齿轮带动电位器旋转，使得电压差为0，电机停止转动。若舵机稳定在初始位置点，控制电路板发出一个PWM信号，舵机全速由初始位置点转向第二位置点，在这个过程中需要一段时间，舵机才能运动到第二位置点。设保持时间为Tw，当Tw≥ΔT时，舵机能够到达目标，并有剩余时间；当Tw≤ΔT时，舵机不能到达目标。理论上：当Tw＝ΔT时，***最连贯，而且舵机运动的最快。It can be understood that the steering gear structure in the present application is an automatic control system composed of a DC motor, a shifting gear set, an adjustable potentiometer and a control circuit board. Specify the angle of rotation of the output shaft by sending a signal. The steering gear generally has a maximum angle of rotation (such as 180 degrees). The control signal enters the signal modulation chip from the channel of the receiver to obtain a DC bias voltage. It has a reference circuit inside, which generates a reference signal with a period of 20ms and a width of 1.5ms, and compares the obtained DC bias voltage with the voltage of the potentiometer to obtain a voltage difference output. Finally, the positive and negative voltage output of the voltage difference to the motor drive chip determines the forward and reverse of the motor. When the motor speed is constant, the potentiometer is rotated by the cascade reduction gear, so that the voltage difference is 0, and the motor stops rotating. If the steering gear is stable at the initial position, the control circuit board sends out a PWM signal, and the full speed of the steering gear is shifted from the initial position to the second position. In this process, it takes a period of time for the servo to move to the second position. Let the holding time be Tw. When Tw ≥ ΔT, the steering gear can reach the target and have the remaining time; when Tw ≤ ΔT, the steering gear can not reach the target. Theoretically: When Tw = ΔT, the system is the most consistent, and the steering gear is the fastest.
