Abstract

The invention discloses a mechanical and visual correlation positioning experiment platform, which comprises a platform, a horizontal movement mechanism arranged on the platform, a vertical movement mechanism arranged on the horizontal movement mechanism, a camera device arranged on the vertical movement mechanism, and The calibration target relative to the imaging device and the vibration source connected with the calibration target, the imaging device is composed of left and right symmetrical cameras, the calibration target is marked with calibration points with different positions, sizes and colors, and the imaging device is connected to the computer for processing. The invention can accurately determine the space coordinate position of the variable target.

Description

technical field [0001] The invention relates to a positioning experiment platform, in particular to a mechanical and visual correlation positioning experiment platform. Background technique [0002] At present, the success rate of fruit-picking manipulators picking fruit at one time is about 50-70%. The main reason for picking failure is that it is difficult to precisely locate the fruit. [0003] The traditional method only considers the correlation correction algorithm of visual positioning, but does not study the relationship between the mechanical positioning error and the visual positioning error of variable target positioning such as biological fruits with external disturbances whose position, size and color are inconsistent. The precise positioning of variable targets by fruit-picking robotic hands is a complex system including technologies such as mechanics, vision, and control. Every picking needs to reposition the variable target, which requires accurate positioni...
