Document Type and Number:
Japanese Patent JP6759450
Kind Code:
B2
Abstract:
The present invention uses a recognition camera 5 to repeatedly capture one-dimensional images of image-capturing ranges Rb, Rc, respectively, by imaging light from the image-capturing ranges Rb, Rc on an image-capturing element 51 by means of a lens 52, while moving a component C (solder S) to the recognition camera 5, and captures two-dimensional images of the component C (solder S). In addition, since the lens 52 of the recognition camera 5 is non-telecentric on an object side, three-dimensional information on the component C (solder S) can be obtained on the basis of the two-dimensional images. In this way, two images viewed from different angles can be captured with one recognition camera 5, and the three-dimensional information on the component C (solder S) can be obtained. As a result, it is possible to suppress cost increase and conveniently acquire the three-dimensional information on the component C (solder S) with high accuracy.
