嗨,大家好,
事实上,我们正在使用CyPress StuffER从控制中心写入FX3到PC的数据。我们从感测器捕获图像并发送到FX3@ 100MHz频率,并且感测器以4帧/秒的速度捕获帧,当我们从数据写入时,每个帧是(752×480,i,360960)。Stuffer-to文件在写入文件时速度非常快,有些数据丢失了。所以我们想减少流线型的写入速度,我们想解决这个数据丢失或移位问题。我已经把输入的图像附加到FX3和写入文件后的图像。F问题请告诉我。 谢谢, 韦伦德拉 小文件名30.JPG 50.9 K 小文件名32.JPG 33.3 K 151.JPG 13 K 以上来自于百度翻译 以下为原文 hi every one, actually we are using cypress streamer to write data from FX3 to Pc in the presense of control center .we are capturing the images from senser and sending to fx3 @ 100Mhz frequency and senser captures the frames at the rate of 4 frames/s each frame is of (752*480 i.e 360960) when we write data from streamer to file it is very fast and some data is missing while writing to the file .so we want reduce the streamer writing speed and we want to solve that data missing or shifting issue .i have attached the input image coming to FX3 and image after writing to files .can any one sorted such kind of issues please let me know. thanks regards , veerendra

你修改了拖缆应用程序直接写在磁盘上吗?如果是这样,可能会有数据丢失。
参考任何在线视频流应用程序,它们是开源的,并在此基础上创建自己的应用程序。 如果数据以100 MHz时钟速率流逝,则很难将其存储在磁盘上。帧率需要降低。对于大多数帧速率和分辨率来说,实时存储可能是不可能的。 (以高数据速率传输视频是可能的,但以正确的速率存储在硬盘上只会导致数据丢失)。 以上来自于百度翻译 以下为原文 Have you modified the streamer application to write directly on disk? If so, there might be data loss. Refer to any online video streaming Applications that are open source and based on that create your own. If the data is streamed at 100 Mhz clock rate, it might be difficult to store it on disk. The frame rate needs to be reduced. Real time storage may not be possible for most of the frame rates and resolutions. (streaming a video is possible with high data rate, but storing on hard disk at such a right rate will only result in data loss) |

shinovo 发表于 2018-10-24 16:22 你好, 这条流线型是由CyPress的员工修改的,我想我得到了这条流线型代码,它只有CyPress中的“保存到磁盘”的选项。我得到了这样的情况,你能告诉我如何降低拖缆速度来获得正确的数据吗? 谢谢, 韦伦德拉 以上来自于百度翻译 以下为原文 hello, this streamer was modified by cypress employees i think i got this streamer code which has save to disk option in that from cypress only .and i am getting such situation can you tell me how to reduce the streamer speed in order to get correct data thanks regards , veerendra |

路YWXZ 发表于 2018-10-24 16:31 嗨,Veerendra, 改性后的流光应用商店传入的数据到磁盘,但它不能用于实时图像或视频捕获。写硬盘需要大量时间和USB传输等以前完成转移。图像采集应用中,流量控制可能与应用程序的当前版本这是不可接受的。目前我们没有任何计划来探讨这样一个应用程序或创建一个可行性。 当做, -马杜 以上来自于百度翻译 以下为原文 Hi Veerendra, The modified streamer app stores the incoming data to the disk, but it cannot be used for real time image or video capture. Writing to harddisk takes considerable time and a USB transfer has to wait until a previous transfer is completed. This is not acceptable for image capturing applications in which flow control may not be possible with the current version of the app. Currently we do not have any plans to investigate the feasibility of such an app or creating one. Regards, - Madhu |

dfzvzs 发表于 2018-10-24 16:45 你好,Madhu Lakshmipathy, 谢谢你的回复,如果我将空洞数据写入单个文件,那么数据也在移动。 至少在单个文件中,它应该写入空洞数据,然后Y在单个文件中移动。 谢谢, 韦伦德拉 以上来自于百度翻译 以下为原文 hello Madhu Lakshmipathy, thanks for you reply ,if i am writing hole data to single file then also data is shifting atleast in single file it should write hole data ,then y it is shifting in a single file thanks regars , veerendra |

路YWXZ 发表于 2018-10-24 16:53 你好,Madhu Lakshmipathy, 再次感谢您把最宝贵的时间献给我的职位,我能得到一些关于FX3和Telever接口的应用笔记吗? 拖缆和控制中心应用说明。如果你发送这些,可能会对我有帮助,因为 6个月的工作我一直牢记Telever是现在写数据到PC现在突然离开希望意味着它非常可怕,所以如果你发送了有关滑行和控制中心的接口申请与FX3接口,以获得数据到PC,我可以进一步按照我们的要求。了解我的处境。 谢谢, 韦伦德拉 以上来自于百度翻译 以下为原文 hello Madhu Lakshmipathy, thanks once again to you to giving your most valuable time towards my posts .Can i get some application notes regarding fx3 and streamer interface and streamer and control center application notes . if u sent those it may be helpful to me because around 6 months i worked keeping in mind streamer is there to write data to pc now suddenly leaving hopes mean its very horrible ,so if u sent sompe application notes regarding streamer and control center for interfacing with fx3 to get data to pc i can move further as per our requirement .I hope you will understand my situation . thanks regards, veerendra |
