    • A personal computer scanner for scanning the three-dimensional (3D) objects has a frame with an axis, and a front plate. The front plate has a large array of axial pinholes that each contain a slidably movable pin to form a bed of pins. A detection device is slidably mounted near the rear of the frame. A stepper motor is used to move the detection device relative to frame. The detection device has a sensor plate on its front surface with an array of sensors that correspond one-to-one with the pins. The user selects an object to be scanned and inserts it into the bed of pins to form an impression. The pins readily move and comply to the contours of the object. After the impression is made, the detection device is slowly incremented by the stepper motor toward the pins. The individual sensors are monitored by a host computer until they have been contacted by their respective pins. When a sensor has been touched by its pin, the sensor is scanned by the computer to record the displacement of the pin. This step is repeated until each paired sensor and pin make contact. With this information, the host computer digitally reconstructs the surface of the object scanned based on the displacements of the pins.
    • 用于扫描三维(3D)物体的个人计算机扫描器具有带轴的框架和前板。 前板具有大的轴向针孔阵列,每个轴孔都包含一个可滑动的销钉,以形成一个针脚。 检测装置可滑动地安装在框架的后部附近。 使用步进电机相对于框架移动检测装置。 检测装置在其前表面上具有传感器板,其具有与销一一对应的传感器阵列。 用户选择要扫描的对象并将其插入针脚以形成印象。 销易于移动并符合物体的轮廓。 在进行印象之后,检测装置由步进电机缓慢地向销引脚。 各个传感器由主机监控,直到它们被相应的引脚接触。 当传感器被其引脚触摸时,传感器被计算机扫描以记录引脚的位移。 重复此步骤,直到每个成对的传感器和引脚进行接触。 使用这些信息,主机基于引脚的位移数字地重建扫描的物体的表面。
