| Abstract: | In the system of IR object recognition,it is needed to collect IR image data in realtime.It is described the collection card for IR image basede on CPCI bus.The card adop t DMA mode of FIFO in the CPCI bus controller to transmitting highspeed image data.This way assure the realtime quality and the veracity and sa tisfy the storage need of a great of data quantity for the system.The collectio n circuit has good compatibility for the multiplicate IR sensor and using this c ard to collection practice data has obtained the nice image. |
