[0019] The specific embodiments of the application will be described below with reference to the accompanying drawings. In order to fully understand the application, many details are described below, but the application can be implemented without these details for those skilled in the art.
[0020] Referring to Figure 1 An elevator inspection detection operation video recording optimization method, comprising the following steps: (1) The elevator inspection and detection work of the operation personnel is recorded by a plurality of cameras throughout the operation, and the recorded video is uploaded to a terminal system; (2) Set several key information as the recognition object, and perform frame-by-frame detection on the video content recorded by each camera through the terminal system, and when the set recognition object is detected, key information marking is performed; (3) According to the key information marking result, at least one key information is selected as a review object, the terminal system retrieves and combines the videos containing the review object recorded by each camera to form an elevator operation review video.
[0021] Referring to Figure 1 , specifically, object recognition is performed on the uploaded video content captured by each camera, and the recognized objects are labeled as key information. The key information includes elevator part information and worker identity information, such as an inspector can select a certain elevator part as a review object, and the terminal system retrieves and arranges the video containing the elevator part from the video captured by each camera to form an elevator work review video of the elevator part, and the video can display the labeled worker identity information therein. The inspector can further screen the retrieved video containing the elevator part for worker identity, and then combine them to help the inspector better determine the corresponding worker identity of the elevator part under different inspection and detection items and different inspection and detection times. For example, an inspector can select a certain worker identity as a review object, and the terminal system retrieves and arranges the video containing the worker from the video captured by each camera to form an elevator work review video of the worker, and the video can display the labeled elevator part therein. The inspector can further screen the retrieved video containing the worker for elevator part, and then combine them to help the inspector better verify whether the worker has missed any elevator part.
[0022] Referring to Figure 2 , a processing method for elevator inspection and detection work recording video, comprising the following steps: (1) recording the elevator inspection and detection work of the worker by a plurality of cameras, and uploading the recorded video to a terminal system.
[0023] The number and distribution of cameras in this step are reasonably arranged according to the actual working environment, but it should be ensured that the shooting pictures of all cameras can fully cover the whole working environment, so as to ensure that the clear and complete working video is recorded in all directions without dead angle. The cameras in the present application include fixed cameras arranged on the safety helmet of the worker and a plurality of movable cameras arranged at specified parts of the elevator. The fixed cameras on the safety helmet can be used for face recognition and recording the detection process in front of the worker, and the movable cameras can be used for recording the surrounding environment and the operation process of the worker during work. After the video is uploaded to the terminal system, the terminal system first detects the clarity of the video. If the clarity detection is not up to standard, the terminal system automatically preprocesses the clarity of the video.
[0024] (2) Set a plurality of key information as recognition objects, and detect the video content captured by each camera frame by frame through the terminal system. When the set recognition object is detected, key information labeling is performed.
[0025] Specifically, the key information includes several elevator site information and the identity information of the operating personnel. The elevator site information refers to the elevator operating site required according to the elevator inspection and detection standard, including elevator machine room, elevator shaft, elevator car and external environment, etc. The identity information of the operating personnel refers to the identity information of all relevant personnel participating in the elevator inspection and detection operation, including name, work number and seniority, etc. A large amount of historical elevator inspection and detection operation video data and operation personnel information data are pre-recorded in the terminal system as learning materials, so that the specified elevator site and the identity of the operating personnel appearing in the subsequently recorded video can be quickly identified. When the recorded video is uploaded to the terminal system, the YOLO model can be used to identify the elevator site, and the facial recognition can be used to lock the feature information of the corresponding operating personnel; then the identification results are associated, so as to accurately label the key information contained in each frame of the recorded video.
[0026] (3) According to the key information labeling result, the video recorded by each camera is cut into several sub-clips, and all the sub-clips are classified and arranged according to each key information.
[0027] For example, all sub-clips containing the key information of the elevator machine room are uniformly placed in the first storage area, and all sub-clips containing the key information of the elevator shaft are uniformly placed in the second storage area, so as to facilitate the integration processing of the next step.
[0028] The terminal system sets a blank key frame on the first frame or the last frame of each sub-clip. In the video re-ordered and synthesized by each sub-clip, the blank key frame can have a good transition effect to reduce the discontinuity between each sub-clip and improve the visual effect of watching. At the same time, placing the blank key on the first frame or the last frame of each sub-clip can clearly label the start and end of each sub-clip, making it easier to identify and segment in subsequent processing.
[0029] (4) Select at least one key information as a review object, sort and integrate all sub-clips containing the key information, so as to form a complete elevator operation review video. This step includes the following sub-steps: a. The terminal system selects information from each elevator section as the review target, sorts and integrates all sub-segments containing the same elevator section in chronological order to form elevator operation review videos for a single elevator section, and uses the name of each elevator section as the index term for its corresponding elevator operation review video. Specifically, after classifying and organizing videos from different angles captured by each camera, the terminal system can further merge sub-segments of the same elevator section from different angles. By searching for elevator operation review videos for each elevator section using the index term, the system verifies whether the operation method of each elevator section meets the requirements. In this way, inspectors only need to enter the name of the elevator section to be inspected to view all videos of the same inspection section at different operation times. Inspectors can further filter these videos by time to accurately locate the specific target inspection video, greatly improving the efficiency of the inspection work.
[0030] b. The terminal system selects the operator's identity as the review target, sorts and integrates all sub-segments containing the same operator's identity in chronological order to form a review video of the elevator operation for a single operator, and uses the operator's name as the index term for the corresponding elevator operation review video. By searching for the elevator operation review video of a single operator using the index term, the system verifies the operator's attendance and whether their operating skills meet the standards.
[0031] c. The terminal system sorts and integrates the elevator operation review videos of all elevator parts within the same date according to the elevator part inspection sequence specified in the elevator inspection and testing operation procedures, thus forming a complete elevator operation review video for that day, and uses the date as the video tag for the corresponding elevator operation review video. By searching for complete elevator operation review videos within a specified date through the video tags, the elevator inspection and testing status can be clearly and completely verified.
[0032] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
