检查装置以及铸造系统
摘要：
检查装置是检查对象物的外观的装置，其具备：拍摄装置，其从第1方向拍摄对象物；照明部，其以从第1位置照射光的第1照射模式以及从与第1位置不同的第2位置照射光的第2照射模式，向对象物照射光；以及控制器，其通过使拍摄装置拍摄以第1照射模式被照射光的对象物而取得第1检查图像，通过使拍摄装置拍摄以第2照射模式被照射光的对象物而取得第2检查图像，并基于第1检查图像、第2检查图像以及预先设置的基准图像来检查对象物的外观，第1位置与第2位置在从第1方向观察时相互重叠。
摘要（英）：

This inspection device is for inspecting the appearance of an object. The inspection device is provided with: an imaging device for imaging the object from a first direction, an illumination unit forirradiating the object with light using a first irradiation pattern in which light is irradiated from a first position and a second irradiation pattern in which light is irradiated from a second position different from the first position, and a controller for acquiring a first inspection image by causing the imaging device to image the object when the object is irradiated with light using the first irradiation pattern, acquiring a second inspection image by causing the imaging device to image the object when the object is irradiated with light using the second irradiation pattern, and inspecting the appearance of the object on the basis of the first inspection image, second inspection image, and a preset reference image. The first position and second position overlap when viewed from the first direction.
