Problems solved by technology

In particular, as people apply machine vision technology to the recognition of characters and graphics on curved surfaces (such as cylinders and spheres), the existing visual light source devices cannot meet the requirements for a good separation of target information and background information in the image. It greatly increases the difficulty of image processing algorithm segmentation and recognition, and at the same time reduces the positioning and measurement accuracy of the system, reducing the reliability and comprehensiveness of the system

Embodiment 1

[0028] refer to Figure 1 to Figure 3 , this embodiment relates to a visual light source device, including a connecting seat 1, a connecting rod 2, a lamp holder 3 and an LED lamp bead 4, the connecting rod 2 is set in multiples, and one end of the connecting rod 2 is hinged to the connecting rod 2 On the seat; the LED lamp bead 4 is fixedly installed on the bottom surface of the lamp holder 3, the lamp holder 3 is set in multiples, and the lamp holder 3 is connected with each connecting rod 2, and the lamp holder 3 is slidable Installed on the connecting rod 2, the LED lamp beads 4 between each of the lamp sockets 3 have different spectrums.

[0029] Each lamp holder 3 of this structure adopts LED lamp beads 4 of different spectra, and the irradiation of the LED lamp beads 4 on each lamp holder 3 on the curved surface can be controlled by adjusting the luminous intensity of the LED lamp beads 4 on different lamp holders 3 At the same time, each lamp holder 3 can slide along ...

Embodiment 2

[0037]This embodiment is based on Embodiment 1, as an improvement to the lamp holder 3, such as figure 1 with Figure 8 As shown, the lamp holder 3 is a bendable arc structure, the LED lamp beads 4 are fixedly installed on the bottom surface of the lamp holder 3, and the LED lamp beads 4 between the lamp holders 3 have different spectrum.

[0038] Replace the bendable ring-shaped LED lamp holder with a bendable arc-shaped LED lamp holder 8, so that the axes formed by the multiple connecting rods 2 are perpendicular to the plane of the connecting seat, and select according to the curvature of the cylinder that needs to be illuminated actually. A connecting seat of a suitable size hinges each connecting rod 2 on the connecting seat, and finally makes the cylindrical arc surface formed by the axes of a plurality of connecting rods 2 parallel to the polished cylindrical surface. Several bendable arc-shaped LED lamp holders 8 are slidably installed on the connecting rod through b...

Abstract

The invention discloses a visual light source device which comprises a connecting base, a plurality of connecting rods, a plurality of lamp holders and LED lamp beads. One ends of the connecting rods are hinged to the connecting base; the LED lamp beads are fixedly mounted on the bottom surfaces of the lamp holders; the lamp holders are connected with the connecting rods correspondingly and are mounted on the connecting rods in a sliding mode; and the LED lamp beads between the lamp holders have different optical spectra. By adoption of the visual light source device, the requirement that target information and background information in cambered images is well separated can be met, the information can be acquired and processed by a machine vision system in the optimal state, and the image processing algorithm partitioning and identification difficulty is greatly lowered; and meanwhile, the positioning and measuring precision of the machine vision system is improved, the reliability and comprehensiveness of the machine vision system are improved, and the visual light source device has the characteristics of adjustable light source, wide application range and convenient application.

Description

technical field [0001] The invention relates to a visual light source device, in particular to a multifunctional visual light source device. Background technique [0002] The core of the machine vision system is image acquisition and processing. Since all data information comes from the image, the quality of the image itself is extremely critical to the entire vision system. The brightness, uniformity, spectral characteristics and contrast of the light source directly affect the quality of the input data and at least 30% of the application effect, which greatly affects the image quality level of the machine vision system. Therefore, a high-quality visual light source device has a great effect on improving the performance of the machine vision system. In particular, as people apply machine vision technology to the recognition of characters and graphics on curved surfaces (such as cylinders and spheres), the existing visual light source devices cannot meet the requirements f...
