Embodiment
[0133] Present embodiment data collection adopts the mode of camera overhead shooting, selects ripe stage strawberry as test object, strawberry parietal leaf and camera lens distance are about 50cm, guarantees that there is at least one complete strawberry in the multi-source image (due to the obtained by PMD camera The image resolution is 200×200 pixels, so a color picture with a spatial resolution of 320×240 pixels is used as supplementary information).
[0134] In this embodiment, the process flow of the three-dimensional modeling method suitable for greenhouse elevated strawberry plants in situ is as follows figure 1 shown, including the following steps:
[0135] Step S101, select the Harris operator as the feature corner point extraction tool, extract the corner points of the intensity image and the color image respectively, and extract 14 pairs of points with the same name according to the gray mean value of the 8 neighborhoods near the corner point as the similarity mea...
