The invention provides a double-camera synchronous counting method and device, and the method comprises the steps: S1, receiving data, and enabling the data of double cameras to enter two video interface controller VIC modules; s2, counting synchronization
processing is carried out in the two VIC modules, wherein a double-counter synchronization mechanism is adopted, and each VIC module comprises an 8-bit counter count 8 and a 32-bit counter count 32; timestamps are added, the timestamps are added into the two data streams, and after a
specific time period, the corresponding timestamps can be hit into the heads of the data streams; the
timestamp is divided into 8-bit counting and 32-bit counting, and when the 8-bit counting reaches the maximum value, the 8-bit counting will carry to the 32-bit counting, S3, outputting the counted and synchronized data to an ISP module for
image processing; s4, after
processing is completed, data of the double cameras are output to a
bus; and S5, merging the two pictures as long as the difference between the two timestamps is within a reasonable threshold range. Accurate image synchronization, high-resolution
timestamp generation and accurate
time information are realized. The low-power-consumption design is stable and reliable.
