A bolt positioning and posture detection method based on monocular and binocular vision cooperation

The invention discloses a bolt positioning and posture detection method based on monocular and binocular vision cooperation. Firstly, a bolt image collected and processed by a binocular vision systemunder a fixed position is used to obtain an edge contour of the bolt image, and the geometrical centroid is calculated to obtain the position coordinates of the feature points in the bolt image. Wheninstalling the two industrial cameras in the binocular system, the left camera is mounted on the left robot arm which can control the movement trajectory, and the right camera is mounted on the properheight of the fixed support of the inspection robot. The left and right camera optical axes are set to be parallel and perpendicular to the baseline, and the right camera interface is closed by the control system after work, and the end of the left manipulator is controlled to move above the acquired coordinate point, at this time, the monocular vision system is operated. The invention combines the function of positioning by using depth information of the binocular system and the flexible 3d posture matching function of the monocular system, and realizes the identification and posture detection of the bolt to be detected in the obstacle environment.

Multiple-effect super absorbent resin fertilizer and manufacturing method thereof

The invention provides a multiple-effect super absorbent resin fertilizer. In the manufacturing process, sodium hydrogen sulfite and ammonium persulfate oxidation-reduction type initiator are used as foundations, and ultraviolet initiation is used as an auxiliary means; N-N'-methylene bisacrylamide is used as a crosslinking foundation, and ethylene glycol diglycidyl ether and glycerol are used as auxiliary means; hydroxyethyl acrylate is added in the polymerized monomer, so that the colloid strength of the high molecular polymer is obviously improved; antioxidant, ultraviolet absorbent and light stabilizer are creatively introduced, thus finally manufacturing super absorbent resin having oxidation resistance, light resistance and degradation resistance; the super absorbent resin is organically combined with humic acid, microbial inoculant and an inorganic fertilizer to perform synergistic action, so that the various effective elements achieve the optimal use effect. Meanwhile, the consumption of the inorganic fertilizer is reduced, the salt content of soil is reduced, the pH value of the soil is improved, the soil environment is improved, and soil hardening is prevented, thus greatly increasing the utilization ratio of nitrogen fertilizers, phosphate fertilizers and potassium fertilizers, and achieving comprehensive effects of water saving, fertilizer saving, yield increase and outcome increase.

Pulping process for environment-friendly kraft board paper

The invention discloses a pulping process for environment-friendly kraft board paper. The pulping process includes the steps that 1, the United States waste paper, England waste paper and European waste paper are mixed uniformly by a certain ratio, wood pulp of a certain ratio is added into the waste paper mixed uniformly, repulping is carried out, and a certain amount of bio-enzyme is added into the repulping process; 2, high-concentration residue removal and screening are carried out on the pulp obtained in the step 1; 3, pulp obtained through screening in the step 2 enters a grading workshop section and is divided into long fiber pulp, middle fiber pulp and short fiber pulp; 4, the three kinds of pulp obtained through grading in the step 3 sequentially pass through respective medium and low concentration residue removal devices to be purified in a residue removal mode; 5, pulp can be obtained by carrying out concentration, heat dispersion and disk milling on the pulp obtained after residue removal. The environment-friendly kraft board paper which is bright in color, high in water resistance and light resistance and consistent in color is manufactured by improving the original pulping process and strictly controlling the beating degree, the temperature and the pH value of the pulp.
