The invention discloses a timestamp marking method and system for a visual component. The method comprises the following steps: acquiring a forming moment of a trigger signal; wherein the trigger signal is generated by the digital integrated circuit chip and is used for triggering the visual component to execute shooting operation; after the visual component executes shooting operation based on the trigger signal, acquiring an interrupt signal generated by the system-on-chip; judging whether the response moment of the interrupt signal is in a preset response time interval or not; wherein the preset response time interval is calculated by starting from the forming moment of the trigger signal, and the forming moment of the trigger signal and the shooting period of the visual component are superposed to serve as the lower limit moment of the preset response time interval; superposing the lower limit time system of the preset response time interval and the system response scheduling time period as the upper limit time of the timestamp response time interval; and if the response moment of the interrupt signal is within the preset response time interval, marking the lower limit moment of the preset response time interval as the timestamp of the shooting data.

    本说明书公开了一种视觉类组件的时间戳标记方法及系统,所述方法包括:获取触发信号的形成时刻;其中,触发信号由数字集成电路芯片产生且用于触发视觉类组件执行拍摄操作;在视觉类组件基于触发信号执行拍摄操作后,获取由系统级芯片产生的中断信号;判断中断信号的响应时刻是否处于预设响应时间区间;其中,预设响应时间区间以触发信号的形成时刻开始计算,将触发信号的形成时刻和视觉类组件的拍摄周期叠加作为预设响应时间区间的下限时刻,将预设响应时间区间的下限时刻系统和系统响应调度时段叠加作为时间戳响应时间区间的上限时刻;若中断信号的响应时刻处于预设响应时间区间内,将预设响应时间区间的下限时刻标记为拍摄数据的时间戳。
