Component image processing apparatus and component image processing method
View Patent ↗To image a component larger than the field of view of a camera, a range based on the shape and dimension of the component to be imaged and the field of view of the camera, a range of the component is divided, and imaging ranges of a plurality of characteristic parts to be imaged are determined. Then, images of the plurality of characteristic parts obtained by imaging the plurality of characteristic parts with the camera are combined to create a combined image of the characteristic parts of the component. Based on the combined image, the position of the component is measured.
1. A component image processing apparatus that partially images a component larger than a field of view of a camera for image processing and measures a position of the component based on a result of the image processing, the apparatus comprising:
imaging range determining means that determines imaging ranges of a plurality of characteristic parts to be imaged obtained by division from a range of the component to be imaged;
combined image creating means that combines images of the plurality of characteristic parts obtained by imaging the plurality of characteristic parts with the camera to create a combined image of the characteristic parts of the component; and
measuring means that measures a position of the component based on the combined image of the characteristic parts of the component,
wherein the imaging range determining means automatically determines the imaging ranges of the plurality of characteristic parts based on either one or both of a shape and dimension of the component to be imaged and the field of view of the camera, and
wherein the imaging range determining means determines two imaging ranges each taking two corners positioned in a diagonal direction of the component to be imaged as characteristic parts.
