Abstract

The invention discloses a simulation verification method for uniform charge transfer dynamic line period imaging, relates to the technical field of simulation verification of charge transfer dynamic line period imaging, and solves the problems that charge transfer is not output, abnormity occurs and the like due to the fact that a jump edge position jumps in a working time sequence designed by adopting an existing method. According to the invention, simulation excitation and test verification are carried out, starting from a mechanism where abnormal phenomena may occur, testing is performed according to the mechanism, test cases are designed according to test conditions, possible problems in design are found in advance, the design period is shortened, and engineering risks are reduced. Through the characteristics of an imaging system, accurate positioning of a possible abnormal line period is carried out, state judgment can be carried out quickly, and the design verification period is saved; and the length of the row cycle is automatically changed at equal intervals through the controller equipment, judgment is performed through the quick-view equipment, the situation that judgment is missed due to manual fatigue is avoided, and meanwhile the judgment speed is increased.

Description

technical field [0001] The invention relates to a simulation verification system for dynamic line cycle imaging of uniform charge transfer, in particular to a simulation verification system for uniform charge transfer dynamic line cycle imaging in an asynchronous working mode while requiring camera synchronization. Background technique [0002] For surveying and mapping camera applications, it is required that the camera synchronization deviation of all detectors in the full-spectrum segment does not exceed 1 pixel clock; the camera synchronization deviation of all detectors in the multi-spectral band does not exceed 1 pixel clock; The camera synchronization between cameras is based on a fixed time delay, and the deviation does not exceed 1 pixel clock. For the CMOS detector application with serial image data output, its operating frequency is an integer multiple of the pixel clock frequency, which requires high jitter, and the use of ordinary cable transmission is prone to ...
