    • A three-dimensional shape measurement apparatus includes a plurality of main pattern illumination parts, a plurality of main image-capturing parts and a control part. The main pattern illumination parts obliquely illuminate grating pattern light in different directions toward a measurement target. The main image-capturing parts obtain a grating pattern image of the measurement target by receiving reflection light of the grating pattern light that is illuminated from the main pattern illumination parts to the measurement target and obliquely reflected by the measurement target. The control part produces height data of the measurement target by using grating pattern images of the measurement target, or produces height data of the measurement target by using image positions of plane images for the measurement target and texture information of the measurement target. The control part employs a grating pattern illuminated on the measurement target as the texture information to produce height data of the measurement target. Thus, a three-dimensional shape may be measured more easily and accurately.
    • 三维形状测量装置包括多个主图案照明部分,多个主图像捕获部分和控制部分。 主图案照明部分朝向测量目标以不同的方向倾斜地照射光栅图案光。 主摄像部分通过接收从主图案照明部分照射到测量目标并被测量目标倾斜反射的格栅图案光的反射光来获得测量目标的格栅图案图像。 控制部通过使用测量对象的光栅图案图像来产生测量对象的高度数据,或者通过使用用于测量对象的平面图像的图像位置和测量对象的纹理信息来产生测量对象的高度数据。 控制部分使用照射在测量目标上的光栅图案作为纹理信息来产生测量目标的高度数据。 因此,可以更容易和准确地测量三维形状。
