Embodiment Construction

[0018] Invention idea of ​​the present invention is:

[0019] Because the task requires the image processing board to be able to receive commands from the main control computer at any time in the non-capturing and tracking state, and update the template and program online. Considering that there may be abnormal conditions such as power failure during the program update process, if the communication processing program and the FLASH erase read / write operation program are placed in the existing application program, when the FLASH read / write operation is being performed, the image processing board is powered off, it may The existing application program in the FLASH storage area is lost or wrong, and after power on, the DSP cannot obtain valid existing application program data from the FLASH storage area, causing the DSP to fail to start work.

[0020] Therefore, the present invention separates the communication processing module and the erasing and reading operation module to FLAS...

Abstract

The invention relates to a device for real-time and on-line updating of an application program and image template data. The device for real-time and on-line updating of the application program and the image template data comprises a FLASH storage chip, wherein a kernel program, the application program and the template data are stored in the FLASH storage chip, the kernel program comprises a communication processing module, a data caching module, a data storage module and a program skipping module. According to the device for real-time and on-line updating of the application program and image template data, a synchronous 422 serial interface is used for receiving uploaded data sent by a main control system, real-time and on-line updating of the template and program data in an image processing panel is achieved through temporary caching, on-line updating and program skipping, and the device for real-time and on-line updating of the application program and the image template data has been applied to a hardware platform of aircraft projects currently.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to a device for updating application programs and image template data online in real time. Background technique [0002] In the process of image guidance, it mainly automatically recognizes and tracks pre-designated strike targets by matching template images and real-time images. In the pre-war preparation stage, it is necessary to upload the pre-strike target template image to the FLASH memory chip of the image processing board in a short period of time. If the corresponding target capture and tracking algorithm, that is, the application program, is also changed, it needs to be completed together with the target template image Online real-time updates. In the test experiment stage, the image processing board can be connected through the emulator, and the FLASH data can be updated manually. In the actual application stage, the image processing board has been packaged, and t...
