The occurrence of events such as small foreign matters in an elevator shaft and fine position changes of equipment can be detected with high precision and low cost. The invention relates to a maintenance device, which is used for checking and maintaining an elevator shaft based on first image data of the elevator shaft shot by a shooting device and second image data of the elevator shaft as a comparison object of the first image data when the elevator is maintained and checked. The maintenance device includes an image analysis unit that performs image analysis of the elevator shaft based on the first image data and the second image data, the image analysis unit including: a difference area calculation unit that generates a first difference image of an image included in the first image data and an image included in the second image data, calculating an area of a difference region included in the first difference image; and a deviation amount calculation unit that calculates a deviation amount between an imaging point of each image included in the first image data and an imaging point of each image included in the second image data, on the basis of the area of the difference region calculated by the difference area calculation unit.
能够高精度且低成本地检测电梯井内的小异物、设备的微细的位置变化等事件的发生。本发明是一种维护装置,基于在电梯维护检查时由拍摄装置拍摄到的电梯井的第一图像数据和成为第一图像数据的比较对象的电梯井的第二图像数据,进行电梯井的检查维护,维护装置包括基于第一图像数据和第二图像数据进行电梯井的图像分析的图像分析部,图像分析部具有:差分面积计算部,该差分面积计算部生成包含在第一图像数据中的图像与包含在第二图像数据中的图像的第一差分图像,计算包含在第一差分图像中的差分区域的面积;以及偏差量计算部,该偏差量计算部基于由差分面积计算部计算出的差分区域的面积,计算包含在第一图像数据中的各图像的拍摄点与包含在第二图像数据中的各图像的拍摄点的偏差量。
