Peach is the fourth largest fruit in China. Peach planting area in China ranks first in the world. In order to improve the utilization rate of pesticides in peach plant protection and enhance the technology of intelligent and accurate target application, human visual characteristics are used as bionic object in this study. Tree crown data is collected through Intel RealSense Depth Camera D435, which will reconstruct the 3 D model of peach tree and provide a foundation for precise and on-demand pesticides application of peach. Firstly, human eye is acted as visual bionic object to study the mechanism of human visual attention and establish a visual bionic model. Then, the depth image and RGB image of peach tree are acquired by Intel RealSense D435, and the interest region is segmented from RGB image. The brightness, direction and color features of the image are extracted by linear filtering, and a Gauss pyramid is built based on multi-resolution analysis method. Local visual contrast is calculated by "center-periphery" operator, and local saliency image is obtained based on normalized combination of normalized operator fusion. The interest region is obtained by segmenting the local saliency image based on the region splitting and merging algorithm. The simulation model of peach tree is reconstructed by matching the segmented image with the depth image based on Intel official SDK. The results showed that the established tree crown model could well retain the 3D morphological characteristics of the tree crown and could provide data support for the target and decision of precise pesticides application.
