In this paper, the principle of camera imaging is studied, and transformation model calibration analyzed. Based on Zhang Zhengyou’s method, an automatic method for monocular binocular cameras developed a multichannel vision platform. The parameters using human-machine interface host computer realized. vision, feasible three-dimensional positioning target points proposed evaluated to provide in ...

To investigate the detection of watermelon seeds exterior quality, a machine vision system based on least square support vector machine was developed. Appearance characteristics of watermelon seeds included area, perimeter, roughness, minimum enclosing rectangle and solidity were calculated by image analysis after image preprocess. The broken seeds, normal seeds and high-quality seeds were dist...

The detection of plants based on a machine vision system is one of the most important parts of plants simulation. The calibration of the machine vision system is a basic step for nondestructive detection. We discuss common methods such as traditional calibration techniques, active vision based calibration techniques, and self-calibration techniques. The results show that it is feasible to apply...

farmers are now more interested in application of weed control methods and tools with less environmental side effects. flame weeding using propane gas is an approach with almost no any chemical residue on the soil and plant surfaces or underground water. in this research, a flame weeding machine with the ability of uniform and also discrete flaming was developed and evaluated in laboratory and ...
