YOLO算法的ZYNQ移植尝试(SDx方法、ARM部分)

尝试直接从官网移植
1.
需要将include/darknet.h文件copy到src
 
2.
发现老是报错,说代码有问题network net = parse_network_cfg(cfgfile);报错
(network和network*的问题),查看源代码,代码应该无问题。。。。
在windows下使用vs编译源代码,看是否能行:发现vs2015安装有问题,一打开软件就软件卡住了,并且可能会导致vs2013使用也出现问题,bug!!
装了几个版本的vs2015都不行,我已经放弃了!!!
 
3.
选用该处的代码,对不必要的代码做删减,尝试使用SDx编译,发现不行,如下的语法解释不了:
#define YOLODLL_API __declspec(dllexport)
 
...
 
       YOLODLL_API Detector(std::string cfg_filename, std::string weight_filename, int gpu_id = 0);
       YOLODLL_API ~Detector();

 

4.
还是选用原始代码,将network net都修改为network *net,然后将net.修改为net->,此类修改(发现源代码中其实也是有部分改了,如yolo.c,有部分没有改)
再将example中的代码和src内的代码都加入源中进行编译
yolo_v2_class.cpp和yolo_v2_class.h,yolo_console_dll.cpp删掉
 
编译通过,但是运行错误

研究发现正确的指令应该是:
./darknet detector test cfg/voc.data cfg/tiny-yolo-voc.cfg tiny-yolo-voc.weights data/dog.jpg

或者(二者等效)

./darknet detect cfg/voc.data cfg/tiny-yolo-voc.cfg tiny-yolo-voc.weights data/dog.jpg

才可,与某一开源代码中的运行方法不一致。

 

换成tiny-yolo.cfg不行,理论上应该将voc.data换为coco.data,但实际换了之后仍然没有检测结果。
以上均应该是cfg文件、weight文件、data文件不匹配造成的。

最后按照这里的源代码移植编译一次,将data.c中的rand_s(&Num)函数修改为Num=rand()编译通过后(rand_s是vs的函数,fpga上编译不通过),终于成功了结果如下:

小结:
使用

root@xilinx-zc706-2017_2:/mnt# ./detect.elf yolo est cfg/tiny-yolo.cfg tiny-yolo.weights data/dog.jpg

均能读出cfg文件,加载weights,运行37s,但是检测结果不显示,要么是指令有误,要么是配置文件有误。

 
使用

能读出cfg文件,加载weights,运行47s,但是检测结果不显示。可能原因是没有指明voc.data,导致的问题

 
使用

能读出cfg文件,加载weights,运行47s,但是检测结果不正确。可能原因是没有指明voc.data,导致的list name错乱,如下:
