Processing device, detection system, processing method, program, and storage medium

Provided are a processing device, a detection system, a processing method, a program, and a storage medium with which it is possible to obtain the position of a welded part of a joined body with higher accuracy. A processing device according to an embodiment receives intensity data of a reflected wave obtained by transmitting an ultrasonic wave toward a joined body in a first direction. The apparatus uses the strength data to determine a weld of the joined body. The apparatus calculates a first center position of the welded portion on a first surface intersecting the first direction. 提供一种能够更高精度地得到接合体的焊接部的位置的处理装置、检测系统、处理方法、程序以及存储介质。实施方式的处理装置接收沿着第一方向朝向接合体发送超声波而获得的反射波的强度数据。所述装置使用所述强度数据来确定所述接合体的焊接部。所述装置计算与所述第一方向交叉的第一面上的所述焊接部的第一中心位置。
