The invention relates to an elevator lift car absolute position detection system and method. The elevator lift car absolute position detection system comprises a shaft, an elevator lift car located in the shaft, reference objects located in the shaft, an imaging device used for continuously shooting the reference objects, and a controller eclectically connected with the imaging device. The imaging device is arranged on the elevator lift car. The reference objects are arranged along the movement tracks of the elevator lift car. The imaging device and the elevator lift car move at the same time, the actual position of the lift car can be truly and reliably detected by conducting shooting and image identifying on the reference objects in the shaft, the detection deflection caused when rotating parts slip during transmission does not exist, the real-time performance is good, and the detection accuracy is improved. The reference objects are shot through the imaging device, special encoding or special image printing does not need to be conducted on the reference objects, application is easy and convenient, cost is low, installation and regulation are convenient, and the application range is wide.
