Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional online detection, and in particular to a three-dimensional online detection method based on a monitoring folder. Background Art

[0002] With the rapid development of optical technology, industrial-grade 3D scanners can quickly capture component appearance information and import it into corresponding 3D inspection software to detect 3D features. With the advent of Industry 4.0, traditional manufacturing methods are facing the transformation and upgrading of intelligent manufacturing, and the demand for automated 3D online inspection of components is increasing. However, current 3D digital online inspection methods suffer from poor performance and low efficiency. Therefore, it is imperative to design a 3D digital online inspection method with improved performance and high efficiency. Summary of the Invention

[0003] To address the shortcomings of existing 3D digital online inspection, which suffer from poor fluency and low inspection efficiency, this invention provides a 3D online inspection method based on a monitoring folder. This method indirectly enables real-time data transmission between the scanning system and inspection software by setting a file path. By monitoring the file queue and searching for the currently scanned file and feature template file, it implements continuous 3D online scanning and automatic inspection, thereby ensuring the simplicity, fluency, and efficiency of 3D digital online inspection applications.

[0004] The above technical problems are solved through the following technical solutions:

[0005] The three-dimensional online detection method based on the monitoring folder is implemented as follows:

[0006] S1. At the scanning end, after the online detection scanning system is started, the parts to be inspected are loaded;

[0007] S2. After the parts to be inspected are loaded, scan the loaded parts;

[0008] S3. Save the scanned file after the scan is completed;

[0009] S4. When the scanned file is saved in the folder, the detection software is started, and the multi-threaded detection software monitors the folder in real time and updates the queue of scanned files or templates to be detected in the detection software in real time;

[0010] S5. After saving the scan file, continue scanning and prepare for the next part loading scan until the scanning is completed;

[0011] S6. At the detection end, the detection software monitors the file queue, which includes a queue of scanned files to be detected and a template queue;

[0012] S7. If the file queue is empty, return to monitoring the file queue;

[0013] S8. If the file queue is not empty, take out the current scan file from the file queue and monitor the corresponding feature template according to the identification monitoring template file of the scan file name;

[0014] S9. If the corresponding template file is not found in the corresponding feature template, return to the monitoring file queue;

[0015] S10. If a corresponding template file is found in the corresponding feature template, the template is loaded;

[0016] S11, import the current scan file and replace the scan data;

[0017] S12, performing recalculation detection of detection features;

[0018] S13, after recalculating the detection, return to the monitoring file queue, and cyclically monitor the detection of the next scanned file in the file queue;

[0019] S14. The online detection loop continues until the scanning end system terminates the scanning.

[0020] This solution is a simple and effective method for implementing 3D scanning online detection based on monitoring folders. The scanning data is indirectly transmitted by setting a file path between the scanning device on the scanning end and the detection software on the detection end. The scanning device and the detection software process independently and in parallel, and the overall detection efficiency is relatively high. This solution provides a reliable, simple and effective method for 3D digital online detection. The method uses the method of setting a file path to indirectly realize real-time data transmission between the scanning system and the detection software. Based on the monitoring file queue, the current scan file and feature template file to be detected are searched to realize continuous 3D online scanning and automatic detection links, thereby ensuring the simplicity, fluency and efficiency of 3D digital online detection applications.

[0021] Preferably, in step S4, after the detection software is started, the multi-threading will monitor the pre-set scan file generation folder, and the newly generated scan file will update the scan file queue or template queue to be detected in real time.

[0022] Preferably, in step S6, after the detection software is started, the generation path of the scanned file is set in advance according to the file path of the scanning system at the scanning end. The detection software monitors the folder where the scanned file is located through multiple threads, and updates the scanned file queue or template queue to be detected in real time.

[0023] The present invention can achieve the following effects:

[0024] The present invention is a simple and effective method for realizing three-dimensional scanning online detection based on monitoring folders. The transmission of scanning data is indirectly realized by setting a file path between the scanning device at the scanning end and the detection software at the detection end. The scanning device and the detection software are independently processed in parallel, and the overall detection efficiency is relatively high.

[0034] S6. At the detection end, the detection software monitors the file queue, which includes a queue of scanned files to be detected and a template queue;

[0035] S7. If the file queue is empty, return to monitoring the file queue;

[0036] S8. If the file queue is not empty, take out the current scan file from the file queue and monitor the corresponding feature template according to the identification monitoring template file of the scan file name;

[0037] S9. If the corresponding template file is not found in the corresponding feature template, return to the monitoring file queue;

[0039] S11, import the current scan file and replace the scan data;

[0040] S12, performing recalculation detection of detection features;

[0041] S13, after recalculating the detection, return to the monitoring file queue, and cyclically monitor the detection of the next scanned file in the file queue;

[0042] S14. The online detection loop continues until the scanning end system terminates the scanning.

[0043] In step S4, after the detection software is started, the multi-threaded program will monitor the pre-set scan file generation folder, and the newly generated scan files will update the scan file queue or template queue to be detected in real time.

[0044] In step S6, see Figure 2 As shown, after the detection software is started, the generation path of the scan file is set in advance according to the file path of the scanning system on the scanning end. The detection software monitors the folder where the scan file is located through multiple threads, and updates the scan file queue or template queue to be detected in real time.
