The invention provides a single-photon distance measuring method and a single-photon distance measuring device for a moving target. The distance measuring method comprises the following steps: dividing the speed range allowed by the target into a first set number speed interval, and acquiring an echo time period detected at each time in each speed interval; detecting the target for second set number times to acquire the time of receiving an echo signal actually at each-time detection, and judging the echo time period of the time of receiving the echo signal actually at each-time detection; andcounting the speed interval corresponding to the echo time period of the time of receiving the echo signal actually at each-time detection to acquire the actual moving speed of the target, and calculating the position of the target during first-time detection and the position of the target during last-time detection according to the moving speed of the target. According to the technical scheme provided by the invention,
