Example Embodiment

[0029]EXAMPLES: The surface of the battery is detected, and the solder joint is located on the metal sheet, and it is necessary to shoot to the solder joint, and it is determined whether the solder joint is soldered. Steps to automatically switch light source: The battery workpiece is transmitted to the light source device, and the industrial camera 2 acquires images under the default light source, and transmits pictures to the industrial computer 1. The image processing module in the industrial computer 1 performs image pre-processing, and then With image recognition, the resulting image is characterized and classified, the classification tag of the obtained battery workpiece is strong reflector, smooth, brightness, and classify the type signal of the battery workpiece into the decision, select high angle annular reflection The light source 4.2 and the low angle strip light source 4.4 are low-definition mode, thereby transmitting the corresponding light source control signal to the...

Abstract

The invention discloses a machine vision light source system capable of automatically switching light source forms and a dimming method, the light source system comprises an industrial camera, a detection workpiece, a switchable light source and an industrial personal computer, and the industrial camera is controlled by the industrial personal computer and transmits image information of the detection workpiece to the industrial personal computer; the detection workpiece is arranged on the transparent conveyor belt; the switchable light source can be directly controlled by an industrial personal computer, different light source combinations and brightness can be switched, and the switchable light source comprises four backlight light sources, namely a low-angle strip-shaped light source vertical irradiation annular light source and a high-angle diffuse reflection annular light source. The industrial personal computer can make decisions by detecting workpiece images, and then controls the switchable light source to select the light source combination meeting the illumination requirement. The light source system and the dimming method are suitable for product detection of multiple varieties and small-batch production modes, light source adjustment can be conducted according to different product types, and automatic switching of different light source forms such as high-angle light sources, low-angle light sources, backlight light sources, common light sources and diffuse reflection light sources is achieved.

Description

technical field [0001] The invention relates to a visual light source device and method, in particular to a light source system and a dimming method capable of adaptively switching machine vision lighting forms. Background technique [0002] The light source system is an important part that directly affects the image quality of machine vision. A suitable light source can enable industrial cameras to obtain pictures that are more suitable for image processing, which in turn can improve image recognition and detection efficiency and simplify system software complexity. However, the current enterprise competition is increasingly emphasizing the competition based on customer needs. Therefore, the production mode of enterprises is gradually shifting to the multi-variety and small-batch production mode based on flexible and automated production. The current light source technology is often only suitable for single product detection, and lacks technology that can be adjusted accord...
