Provided are an elevator and an elevator diagnostic method that do not require strict adjustment of the angle of a camera. A camera (14) provided on a car (8) of an elevator (1) captures a feature point that moves in a hoistway (2) as the car (8) moves. In an elevator (1), the relative position of a feature point is calculated on the basis of the position of a car (8) acquired by a car position detector. The relative position of the feature point is the position of the feature point when the car (8) is located at the first car position, and the position of the feature point when the car (8) is located at the second car position, based on the position of the feature point when the car (8) is located at the first car position. The position of the feature point when the car (8) is located at the reference car position is calculated on the basis of the relative position of the calculated feature point, the position of the car (8) acquired by the car position detector, and the images of the feature point captured by the camera (14) when the car (8) is located at the first car position and the second car position. The state of the elevator (1) is determined on the basis of the calculated position of the feature point.
提供不需要严格调整照相机的角度的电梯及电梯的诊断方法。设置在电梯(1)的轿厢(8)上的照相机(14)拍摄随着轿厢(8)的移动而在升降通道(2)中移动的特征点。在电梯(1)中,基于轿厢位置检测器取得的轿厢(8)的位置,计算特征点的相对位置。特征点的相对位置是以轿厢(8)位于第一轿厢位置时的特征点的位置为基准的、轿厢(8)位于第二轿厢位置时的特征点的位置。基于计算出的特征点的相对位置、轿厢位置检测器取得的轿厢(8)的位置、以及轿厢(8)位于第一轿厢位置和第二轿厢位置时照相机(14)拍摄到的特征点的图像,计算轿厢(8)位于基准轿厢位置时的特征点的位置。基于计算出的特征点的位置,判定电梯(1)的状态。
