Embodiment 1
[0113] Embodiment 1: The machine vision-based image acquisition and reconstruction method provided in this embodiment includes the following steps:
[0114] 1) Using a full-frame image digital acquisition instrument, through the set image acquisition mechanism, image acquisition of the material to be tested with a specific shape or pattern information;
[0115] 2) Set up an image processing mechanism to sequentially process the collected images as follows:
[0116] a) CIS splicing processing;
[0117] b) Image consistency correction processing;
[0118] c) High-precision image resampling processing;
[0119] d) Bitmap to vector processing, and output the obtained vector data;
[0120] 3) According to the output vector data, vectorized reconstruction of the specific shape or set pattern information of the material to be tested.
[0121] See Figure 1-Figure 2 , The said full-frame image digital acquisition instrument includes a platform 1 and an image acquisition mechanism 2 arranged in rel...
Embodiment 2
[0212] Embodiment 2: The machine vision-based image acquisition and reconstruction method and device provided in this embodiment are basically the same as the embodiment 1. The machine vision-based image acquisition and reconstruction method is the same as the embodiment, and the machine vision-based The differences between the image acquisition and reconstruction methods are:
[0213] See Figure 3-6 The said full-frame image digital acquisition instrument includes a platform 1 and an image acquisition mechanism 2 set in relative motion with the platform. The image acquisition mechanism 2 is provided with an image acquisition combination camera 21 formed by successively arranging and stitching several image sensors. The image sensor is a CIS linear image sensor. The image acquisition combined camera 21 is set on the image acquisition mechanism 2 through a lifting mechanism 22, which can be moved up and down to adjust the distance relative to the platform 1. The lifting mechanism...
