[0044] When the processing function of the measured ISP chip 2 is abnormal and affects the quality of imaging, the image displayed by the measured display device 3 is abnormal, that is, when the measured ISP chip 2 is abnormal in the actual vehicle test, the camera 1 and the measured ISP chip 2 are no longer transmitted data, and the camera 1 directly sends the raw data to the storage medium 4, and the storage medium 4 stores the raw data. Among them, the storage medium 4 can be a portable laptop, mobile hard disk, etc., and the storage medium 4 can carry the raw data of the abnormal situation back to the infield and provide it to the R&D design personnel for abnormal situation analysis.

Figure 2As shown, the simulation test system used by the R&D personnel during the simulation test includes a storage medium 4, a simulation system 5, a simulation ISP chip 2' and a simulation display device 3'. The simulation system 5 is respectively connected to the simulation ISP chip 2' and the storage medium 4 in communication, that is, the simulation ISP chip 2' and the storage medium 4 are respectively connected to the simulation system 5 in communication, and the storage medium 4 is used to provide the simulation system 5 with the original data of the abnormal condition caused by the measured ISP chip 2 during the actual vehicle test; the simulation system 5 is used to reproduce the data stream when the measured ISP chip 2 is processed according to the original data and the camera configuration parameters; the simulation ISP chip 2' is used to provide the simulation system 5 with the camera configuration parameters, and process the data stream to reproduce the abnormal condition, and the simulation display device 3' is connected to the simulation ISP chip 2' in communication, and is used to display the abnormal condition through an image. Among them, the simulation ISP chip 2' and the measured ISP chip 2 are the same ISP chips, and the simulation display device 3' and the measured display device 3 can be the same display device or different display devices.

[0047] The simulation system 5 includes a preliminary processing module 10 , a storage module 20 , a control module 30 , a cache module 40 , a camera simulation module 50 and a parameter control module 60 .

[0049] The preliminary processing module 10 is connected to the storage medium 4 in communication, and is also connected to the storage module 20. The preliminary processing module 10 is used to call the original data from the storage medium 4, re-encode the original data to obtain transition data, and finally send the relevant parameters of the original data and the transition data to the storage module 20. The preliminary processing module 10 is, for example, database software, and the preliminary processing module 10 includes a simulation database 11. The database software is connected to the storage medium 4 in communication, and is also connected to the storage module 20. The database software is used to call the original data in the storage medium 4, and classify and organize the original data into the simulation database 11. The database software also re-encodes the original data in the simulation database 11 according to a specified format to obtain transition data, and finally sends the transition data to the storage module 20, and also sends the relevant parameters of the original data (such as image size, original data type, configuration parameters of the camera 1, etc.) to the storage module 20.

[0062] Next, when an abnormal situation occurs in the processing of the measured ISP chip 2, the camera 1 directly sends the original data to the storage medium 4, and the storage medium 4 stores the original data.

[0063] Then, step S2 is executed, wherein the simulation system 5 reproduces the data stream when an abnormal situation occurs according to the original data and the camera configuration parameters provided by the simulation ISP chip 2'.

[0064] This step specifically includes:

[0065] First, the preliminary processing module 10 calls the original data from the storage medium 4 and re-encodes the original data to obtain transition data, and then sends the relevant parameters of the original data and the transition data to the storage module 20.

[0066] Next, the control module 30 automatically reads the transition data from the storage module 20 according to the relevant parameters of the original data, and sends the transition data to the cache module 40. Next, the camera simulation module 50 automatically reads the transition data from the cache module 40, and reproduces the data flow when the actual ISP chip 2 processes an abnormal situation according to the camera configuration parameters provided by the simulated ISP chip 2' and the transition data.

[0067] Then, step S3 is performed, the simulated ISP chip 2' processes the data stream to reproduce the abnormal condition. In detail, the simulated ISP chip 2' processes the data stream to reproduce the abnormal condition, and the simulated display device 3' displays the abnormal condition through an image.
