Embodiment Construction
[0054] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0055] a. Overall description
[0056] Because the depth of field of common cameras is limited, and the position and size of workpieces vary greatly, the fixed-position cameras cannot capture all workpieces clearly. A reasonable method is to set different camera positions for different workpieces, which requires the assistance of the front module 1 . The present invention proposes as figure 1 The workpiece shooting system shown (also called: camera system) is composed of two module systems working together, wherein the front module 1 is used to: detect the position and size of the workpiece 7, and the rear module 2 is based on the detection of the front module 1 As a result, the camera 3 5 is adjusted to the optimal shooting position through the displacement platform 6 .

The invention belongs to the technical field of workpiece measurement, and relates to a workpiece adaptive shooting method, which comprises the following steps: S1, a front module detects the position and the size of a workpiece, and transmits a detection result to a rear module; and S2, the rear module adjusts a third camera to an optimal shooting position through a displacement platform according to a detection result of the front module. The system has the following beneficial technical effects: a, a very large space distance can be reserved between the front module and the rear module, so that the rear module can have enough time to adjust the position of the camera III through the displacement platform, and the image focusing is accurate; and b, the displacement platform has a quite large displacement adjustment range, so that the focusing range of the third camera is quite large, which is an outstanding advantage compared with a common zoom lens. And c, through the pre-detection of the front module, the optimal shooting position can be set for each workpiece on the conveying belt.
Description
technical field [0001] The invention belongs to the technical field of workpiece photography, and relates to a workpiece self-adaptive photography method. Background technique [0002] At this stage, on the production line of the manufacturing industry represented by the automobile industry, there are various types of parts and complex processes, and most of the process links require manual intervention. This has caused difficulties in production management and high labor costs. On the other hand, Also frequently due to human factors lead to production quality problems. Continuously improving the automation of the production process is the best choice to deal with these problems, and it is also the goal that the manufacturing industry continues to pursue. In particular, for the detection of manufacturing defects of auto parts, manual visual inspection is mainly used at present. Considering the rapid development of computer vision methods based on deep learning technology in...
