Embodiment 1

[0081] Example 1. Reference figure 1 -4. The ring light source is composed of a main light source 2 and a back light source 3. The main light source 2 is composed of a concentric circular luminous band formed by four LED point light sources 4 fixed on the bottom plate 5, which maintains the rotation invariance of the captured tool texture. The backlight source 3 is composed of a support plate 6, a diffuse reflection plate 7, a box body 8, a light source 9 and a reflective layer 10; the box body 8 is made of a PVC board and has a rectangular parallelepiped with an opening on the top. The reflective layer is a reflective film that is uniform. Ground attached to the inner surface of the box body, the LED point light sources 4 are evenly arranged on the lower bottom plate of the box body 8 to form the light source 9, and the diffuse reflection plate 7 is located under the support plate 6 and fixed on the box body 8. The main light source 1 adopts 142 LED point light sources 4 arr...

Embodiment 2

[0082] Example 2. The specific steps of the fusion recognition method based on the tool shape texture weight using the ring light source are as follows.

[0083] In this embodiment, the shape and texture information acquisition camera 1 is an industrial camera of the MV1300 model of Weishi Digital Image Technology Co., Ltd., and the distance between the camera and the target to be measured is 30 cm.

[0084] In this embodiment, a cylindrical tool with a tool number of 0008 and a tool diameter of φ10 is selected from the tool database, and its shape and texture are photographed, and its weight information is obtained through a gravity sensor. With the support of the main light source 2 and the backlight source 3, the shutter speed is selected as 20ms, the gain adjustment is 0, the screen mode is 640*512, and the acquisition speed is high. The image collected by the MV1300 industrial camera is used as an implementation example under the reading tooling, and the image size is 640*512...

Abstract

The invention discloses a ring illuminator and a fusion recognition method utilizing ring illuminator illumination based on the shape, the grain and the weight of a tool. The ring illuminator and the fusion recognition method utilizing the ring illuminator illumination based on the shape, the grain and the weight of the tool are used for solving the technical problem that an existing ring illuminator cannot accurately obtain all the grain information of the tool. According to the technical scheme, the ring illuminator is composed of a main light source and a back light source, the main light source is composed of four concentric circle light emitting bands which are fixed to a base plate and are formed by LED point light sources, the light emitting bands are composed of LEDs with equal distances, and rotation invariance is maintained for the shot tool grain. The back light source is composed of a supporting plate a diffuse reflection plate, a box body, light sources and a reflecting layer. The box body is made of PVC plates, the reflecting layer is a reflecting film, the reflecting film is evenly attached to the inner surface of the box body, the LEDs are evenly arranged on the lower bottom plate of the box body at intervals to form the light sources, the diffuse reflection plate is arranged above the light sources and below the supporting plate, scattering light beams which are low in luminance and good in uniformity are generated, the shadow effect of the tool under natural light is eliminated, and all the grain information of the tool is obtained.

Description

Technical field [0001] The invention relates to a ring light source, and also to a fusion recognition method based on the shape and texture weight of a tool by using the ring light source to illuminate. Background technique [0002] Real-time and accurate acquisition of tool information on the bottom of the workshop of a discrete manufacturing enterprise, and real-time feedback of this information to the scheduling layer and planning layer are the keys to real-time tool tracking and efficient tool scheduling. The high degree of data sharing leads to high requirements for the timeliness and accuracy of data information in the tool management system. The lack of information will inevitably affect the efficiency of the system, and the inaccuracy of data will reduce the credibility of the system. The tool management system itself has many disadvantages. Tool identification plays an important role in tool tracking, tracing and monitoring. [0003] Document 1 "Patent Publication No. CN...
