The invention discloses a steel rail fastener state dynamic visual detection method and device. The method comprises the following steps that a high-definition linear array push-broom imaging sensor and a laser visual sensor are built, and an electrical control and data processing device is built; triggering a high-definition linear array push-broom imaging sensor and a laser vision sensor to respectively carry out image acquisition; matching and fusing the data; and performing dynamic visual detection on the state of the steel rail fastener. According to the invention, two-dimensional image acquisition is carried out through the high-definition linear array push-broom imaging sensor, three-dimensional measurement is carried out through the laser vision sensor, data processing is carried out through the PLC, all-weather, all-time, multi-vehicle-type and multi-type steel rail fastener state intelligent detection is realized, and related detection results are sent to train inspection personnel in time; therefor
