VideoPipe視覺化視訊結構化框架新增功能詳解(2022-11-4)

2022-11-04 18:01:22

VideoPipe從國慶節上線原始碼到現在經歷過了一個月時間,期間吸引了若干小夥伴的參與,現將本階段新增內容總結如下,有興趣的朋友可以加微信拉群交流。

跟蹤外掛

新增了跟蹤外掛,同時實現了預設的SORT目標跟蹤演演算法,後期擴充套件Deep SORT演演算法非常方便。下面是車輛跟蹤的效果(底部是pipe執行狀態圖):

下面是人臉跟蹤的效果:

 

錄影和截圖外掛

新增了錄影截圖外掛,同時提供了一個人工模擬錄影或截圖的介面供測試。當用戶向管道中傳送錄影、截圖控制指令時,錄影截圖外掛就開始非同步工作。下面是非同步錄影原理:

 

紀錄檔庫

新增了一個輕量級的紀錄檔庫,支援多執行緒非同步紀錄檔寫入、支援紀錄檔檔案自動拆分。紀錄檔沒使用第三方庫,下面是紀錄檔使用方法和效果:

 1 // log level
 2 VP_SET_LOG_LEVEL(_log_level);
 3 // log file dir
 4 VP_SET_LOG_DIR(_log_dir);
 5 
 6 // log to console or not
 7 VP_SET_LOG_TO_CONSOLE(_log_to_console);
 8 // log to file or not
 9 VP_SET_LOG_TO_FILE(_log_to_file);
10 // TO-DO
11 VP_SET_LOG_TO_KAFKA(_log_to_kafka);
12 
13 // include log level or not
14 VP_SET_LOG_INCLUDE_LEVEL(_include_level);
15 // include code location or not (where the log occurs)
16 VP_SET_LOG_INCLUDE_CODE_LOCATION(_include_code_location);
17 // include thread id or not (std::this_thread::get_id())
18 VP_SET_LOG_INCLUDE_THREAD_ID(_include_thread_id);
19 
20 // warn if log cache in memory exceed this value
21 VP_SET_LOG_CACHE_WARN_THRES(_log_cache_warn_threshold);

sample程式碼

新增加13個sample檔案,可以獨立執行,涵蓋pipe結構、各種外掛使用舉例。下面是1-1-1 sample程式碼和效果:

 1 #include "VP.h"
 2 
 3 #include "../nodes/vp_file_src_node.h"
 4 #include "../nodes/infers/vp_yunet_face_detector_node.h"
 5 #include "../nodes/infers/vp_sface_feature_encoder_node.h"
 6 #include "../nodes/osd/vp_face_osd_node_v2.h"
 7 #include "../nodes/vp_screen_des_node.h"
 8 #include "../nodes/vp_rtmp_des_node.h"
 9 
10 #include "../utils/analysis_board/vp_analysis_board.h"
11 
12 /*
13 * ## 1-1-1 sample ##
14 * 1 video input, 1 infer task, and 1 output.
15 */
16 
17 #if _1_1_1_sample
18 
19 int main() {
20     VP_SET_LOG_INCLUDE_CODE_LOCATION(false);
21     VP_SET_LOG_INCLUDE_THREAD_ID(false);
22     VP_LOGGER_INIT();
23 
24     // create nodes
25     auto file_src_0 = std::make_shared<vp_nodes::vp_file_src_node>("file_src_0", 0, "./test_video/10.mp4", 0.6);
26     auto yunet_face_detector_0 = std::make_shared<vp_nodes::vp_yunet_face_detector_node>("yunet_face_detector_0", "./models/face/face_detection_yunet_2022mar.onnx");
27     auto sface_face_encoder_0 = std::make_shared<vp_nodes::vp_sface_feature_encoder_node>("sface_face_encoder_0", "./models/face/face_recognition_sface_2021dec.onnx");
28     auto osd_0 = std::make_shared<vp_nodes::vp_face_osd_node_v2>("osd_0");
29     auto screen_des_0 = std::make_shared<vp_nodes::vp_screen_des_node>("screen_des_0", 0);
30 
31     // construct pipeline
32     yunet_face_detector_0->attach_to({file_src_0});
33     sface_face_encoder_0->attach_to({yunet_face_detector_0});
34     osd_0->attach_to({sface_face_encoder_0});
35     screen_des_0->attach_to({osd_0});
36 
37     file_src_0->start();
38 
39     // for debug purpose
40     vp_utils::vp_analysis_board board({file_src_0});
41     board.display();
42 }
43 
44 #endif
