Polycrystalline silicon block material picking method and device

The invention discloses a polycrystalline silicon block material picking method. The method comprises the following steps of acquiring an image of a block material; comparing the image of the block material with a standard block material, and judging whether the block material is a qualified block material or not according to a comparison result; and placing the block material judged to be unqualified in an abnormal material box. Correspondingly, the invention further provides a polycrystalline silicon block material picking device. According to the picking method, the picking identification degree can be improved, and the picking efficiency is improved. 本发明公开一种多晶硅块料的挑拣方法，包括：获取块料的图像；将块料的图像与标准块料进行比对，并根据比对结果判断块料是否为合格块料；将判断为不合格块料放置在异常料盒中。相应的，本发明还提供一种多晶硅块料的挑拣装置。该挑拣方法能够提高挑拣辨识度，并提高挑拣效率。
