Description
TECHNICAL FIELD
[0001] The utility model belongs to the industrial vision technical field, and specifically relates to an industrial top recognition device. BACKGROUND
[0002] In today's industrial assembly field, achieving high-precision and high-efficiency assembly operation has been the goal pursued by the industry. Although the traditional 2D vision technology has promoted the industrial automation process to a certain extent, it can only obtain planar image information, and has many limitations when facing complex three-dimensional structure assembly tasks. For example, for parts with complex shapes, 2D vision cannot accurately identify their posture and position, especially in complex environmental conditions such as occlusion and light changes, the recognition effect is greatly reduced, and misjudgment and assembly errors are easily caused.
[0003] 3D vision technology can obtain three-dimensional spatial information of objects, making up for the deficiency of 2D vision in depth perception. 3D vision technology realizes three-dimensional information acquisition in various ways. For example, the structured light technology projects a specific pattern onto the surface of an object through a projector, and obtains three-dimensional information according to the pattern deformation; the laser line scanning technology scans the object with a laser, and calculates the three-dimensional coordinates of the object by measuring the time or angle of reflected light; the time-of-flight (ToF) technology determines the distance of an object by measuring the time difference between the emission and reception of light signals, thereby constructing a three-dimensional model.
[0004] However, single 3D vision technology also has certain limitations in some scenarios. For example, the measurement accuracy of structured light technology is severely affected when facing transparent, black or strongly reflective surfaces; although the laser line scanning technology is fast, it may have data missing when acquiring complete three-dimensional information of complex-shaped objects; the ToF technology has relatively high cost, which limits its widespread application in some cost-sensitive application scenarios.
