在detector.c中增加如下所示代码段，即可进行批量图像测试

void test_batch_detector(char *datacfg, char *cfgfile, char *weightfile, char *filename, float thresh, float hier_thresh, char *outfile, int fullscreen)
    {
    	list *options = read_data_cfg(datacfg);
    	char *name_list = option_find_str(options, "names", "data/names.list");//home/YL/darknet-master-v3/backup/yolov3_fisheye_fullimage/1_cls_cfg/hs.names
    	char **names = get_labels(name_list);
    
    	image **alphabet = load_alphabet();
    	network *net = load_network(cfgfile, weightfile, 0);
    	set_batch_network(net, 1);
    	srand(2222222);
    	double time;
    	char buff[256];
    	char *input = buff;
    	float nms = .45;
    	
    	list *plist;
    	char **paths;
    	int m;
    	int i =0;
    	if(filename)
    	{
    		plist = get_paths(filename);
    		paths = (char **)list_to_array(plist);
    		m = plist->size;
    		i = 0;
    	}
    	for(i=0;i<m;i++)
    	{
    		if(1)
    		{
    			strncpy(input,paths[i],256);
    			printf("%s\n",paths[i]);
    			printf("Total Img Num:%d\n",m);
    			printf("Predict Img Index:%d\n",i);	
    		}
    		else
    		{
    			printf("Enter Image Path: ");
    			fflush(stdout);
    			input = fgets(input, 256, stdin);
    			if (!input) return;
    			strtok(input, "\n");
    		}
    		image im = load_image_color(input, 0, 0);
    		image sized = letterbox_image(im, net->w, net->h);
    	    //image sized = resize_image(im, net->w, net->h);
    		//image sized2 = resize_max(im, net->w);
    		//image sized = crop_image(sized2, -((net->w - sized2.w)/2), -((net->h - sized2.h)/2), net->w, net->h);
    		//resize_network(net, sized.w, sized.h);
    		layer l = net->layers[net->n - 1];
    		float *X = sized.data;
    		time = what_time_is_it_now();
    		network_predict(net, X);
    		printf("%s: Predicted in %f seconds.\n", input, what_time_is_it_now() - time);
    		int nboxes = 0;
    		detection *dets = get_network_boxes(net, im.w, im.h, thresh, hier_thresh, 0, 1, &nboxes);
    		//printf("%d\n", nboxes);
    		//if (nms) do_nms_obj(boxes, probs, l.w*l.h*l.n, l.classes, nms);
    		if (nms) do_nms_sort(dets, nboxes, l.classes, nms);
    		draw_detections(im, dets, nboxes, thresh, names, alphabet, l.classes);
    		free_detections(dets, nboxes);
    		int count = i;
    		char tmp[10];
    		sprintf(tmp,"%d",count);
    		printf("string itoa:%d\n",i);
    		char tmp_out[256];
    		strncpy(tmp_out,outfile,256);
    		strcat(tmp_out,tmp);
    		if (outfile)
    		{
    			save_image(im, outfile);
    		}
    		else 
    		{
    			save_image(im, "predictions");
    #ifdef OPENCV
    			//cvNamedWindow("predictions", CV_WINDOW_NORMAL);
    			if (fullscreen) 
    			{
    				//cvSetWindowProperty("predictions", CV_WND_PROP_FULLSCREEN, CV_WINDOW_FULLSCREEN);
    			}
    			//show_image(im, "predictions");
    			//cvWaitKey(0);
    			//cvDestroyAllWindows();
    #endif
    		}
    		free_image(im);
    		free_image(sized);
    		
    	}
    }

主函数也要做如下修改：

void run_detector(int argc, char **argv)
    {
        char *prefix = find_char_arg(argc, argv, "-prefix", 0);

        if(argc < 4){
            fprintf(stderr, "usage: %s %s [train/test/valid] [cfg] [weights (optional)]\n", argv[0], argv[1]);
            return;
        }
        char *gpu_list = find_char_arg(argc, argv, "-gpus", 0);
        char *outfile = find_char_arg(argc, argv, "-out", 0);
        int *gpus = 0;
        int gpu = 0;

        if(gpu_list){
            printf("%s\n", gpu_list);
            int len = strlen(gpu_list);
            ngpus = 1;
            int i;
            for(i = 0; i < len; ++i){
                if (gpu_list[i] == ',') ++ngpus;
            }
            gpus = calloc(ngpus, sizeof(int));
            for(i = 0; i < ngpus; ++i){
                gpus[i] = atoi(gpu_list);
                gpu_list = strchr(gpu_list, ',')+1;
            }
        } else {

            gpus = &gpu;
            ngpus = 1;
        }
    
        int clear = find_arg(argc, argv, "-clear");

        //int class = find_int_arg(argc, argv, "-class", 0);
    
        char *datacfg = argv[3];
        char *cfg = argv[4];
        char *weights = (argc > 5) ? argv[5] : 0;
        char *filename = (argc > 6) ? argv[6]: 0;
        if(0==strcmp(argv[2], "test_batch")) test_batch_detector(datacfg, cfg, weights, filename, thresh, hier_thresh, outfile, fullscreen);

            char *name_list = option_find_str(options, "names", "data/names.list");
            char **names = get_labels(name_list);
            demo(cfg, weights, thresh, cam_index, filename, names, classes, frame_skip, prefix, avg, hier_thresh, width, height, fps, fullscreen);
        }
