摘要 针对手工制作生物组织微阵列作业效率低和不易保证质量等问题,研制了一种生物组织微阵列数控加工系统。利用数控和图像识别技术,实现自动打孔、自动定位填埋和组织提取等操作,实现了生物组织微阵列制作的自动化。采用最小二乘拟合算法对目标像素点进行拟合,获得微孔的特征参数,对偏离视景范围的微孔图像进行自动纠偏精确定位处理,避免了手工操作视觉偏差,提高加工精度。 To enhance manufacture efficiency and product quality,a NC manufacture system for bio-tissue micro-array was developed. The results of experiment demonstrate that the system can accomplish the operations such as auto-punching,accurate position and filling,and abstraction of tissue by using NC and digital image recognition,thus fulfill the requirements to automatic manufacture of tissue micro-array. The characteristic parameters of microporosity were obtained through fitting the target pixel paints by using the least square fit algorithm. And the microporosity image deviating from the visual range can be automatically rectified to the proper range and be accurately positioning. The visual error of the operators was avoided,so the NC manufacture system has high accuracy.
