The invention discloses a video crowd counting system and method. A front-end encoder performs feature extraction on a frame of image in a given video sequence; the common supervision module suppresses interference of a fixed background in a scene by utilizing related characteristics between a previous frame and a to-be-detected frame in a video sequence; the spatial attention module selects an attention area by utilizing shallow structure characteristics, and guides the system to distinguish foreground crowds from background interference; the multi-scale self-supervision module extracts different scale features of the crowd in the image through a multi-branch structure by using deep semantic features, adaptively integrates context feature information through a self-attention mechanism, and autonomously selects the most suitable scale branch feature; and the rear-end decoder is used for fusing the features extracted by the three modules and outputting a predicted crowd density map so as to calculate the number of people contained in the to-be-detected video frame. According to the invention, crowd number estimation is carried out on each contained frame of image according to the video sequence, and dense crowd counting for the video sequence is realized.

The invention discloses a DDR-based reading data synchronization method and system. The method uses a frequency divider to input a data strobe signal half-inpu-dqs-n as a DDR interface DQS signal, a sampling clock internal-clk serves as a sampling clock in a DDR controller, a transition clock is set up as a synchronous clock between the DDR interface DQS signal and the sampling clock in the DDR controller, and the synchronous clock achieves the synchronization of the sampling clock in the DDR controller and an input color outside the DDR and achieves asynchronous transmission of DDR interfaceDQS domain data and domain data of the sampling color in the DDR controller.

Intermediate position feedback control is executed when valve timing of an intake valve is at an intermediate lock position, an intermediate lock is needed, and an engine revolution speed is greater than a first engine revolution speed R1. Forced lock control is executed when the valve timing of the intake valve is at the intermediate lock position, the intermediate lock is needed, the engine revolution speed is less than the first engine revolution speed R1, and the intermediate position feedback control is not being executed. As a result, even when the engine revolution speed increases in the presence of a demand that the valve timing needs to be in the intermediate lock position, it is possible to maintain the valve timing at the intermediate lock position.
