将CopyConvertedFrameDataToArray与LockRawImageBuffer进行比较的性能是什么 [英] What is the performance comparing CopyConvertedFrameDataToArray with LockRawImageBuffer

问题描述

 在Class ColorFrame中，我找到了一些将帧数据复制到数组的方法，还有一个方法-LockRawImageBuffer。在Sdk浏览器中，演示使用了lockRawImageBuffer.Is LockRawImageBuffer方法之前的复制方法在性能上？谢谢！

  In Class ColorFrame,I find some methods that copy frame data to array,also there is a method-LockRawImageBuffer.In Sdk browser,the demos use the lockRawImageBuffer.Is the LockRawImageBuffer methods prior with copy methods in performance?Thank you!

推荐答案

答案取决于您对数据的处理方式以及如何从原始缓冲区复制数据。副本是数据的优化/并行副本。如果您锁定缓冲区并按顺序访问它，则复制速度会更快。
副本将转储整个帧，并使用颜色进行转换。使用锁定，您必须进行颜色转换，但您可以访问具有偏移量的特定区域。 

The answer depends on what you are doing with the data and how you make your copy from the raw buffer as apposed to getting a copy. The copy is an optimized/parallel copy of the data. If you lock the buffer and access it sequentially then the copy is faster. The copy will dump the entire frame, and with color, do a conversion. Using the lock, you would have to do a color conversion, but you can access specific areas with an offset.
