[0142] Aiming at the disadvantages of weak robustness, insufficient reliability and accuracy, and long drawing time in the prior art, the present invention proposes a new robot drawing method to demonstrate the intelligence of the robot. In order to extract image features, the present invention proposes a feature extraction method based on a mixture of global binarization and local binarization techniques; An optimal path planning method is proposed to generate the optimal path for drawing a picture.

[0143] figure 2 It is the overall framework of the robot portrait system proposed by the present invention. Among them, the input image is a color photo taken by a camera. However, the drawn image is a black and white image, and the drawing process is time-consuming, so the drawn image should be as concise as possible. Therefore, features that can express the source image must be extracted. The features extracted by the present invention refer to some closed areas that can ...

[0205] In order to verify the effect of the method of the present invention, the present invention proposes Figure 7 The experimental system shown is used for experimental verification. like Figure 7 As shown, the experimental system includes a camera and an ABB IRB120 industrial robot equipped with a marker pen. The markers are attached to the robot through a specially designed container that contains a spring that allows the markers to move more smoothly across the paper. The feature extraction and path planning algorithms are implemented using C#, and the corresponding programs run on a laptop.

[0206] The specific process of this embodiment is as follows:

[0207] (1) Feature extraction

[0208] The output of each step of feature extraction is as Figure 8 A-E are shown. Wherein, the source image A is a photo after face extraction using the OpenCV program; Figure 8 B and C are the results of local binarization and global binarization respectively, and the parame...

Abstract

The invention discloses an image drawing method and system for an intelligent robot. The method includes: inputting a source image to be drawn; using a method based on mixed binary image processing to extract features from the source image to obtain a region to be filled by the robot; The region to be filled of the robot adopts the path optimization algorithm for region segmentation and optimal path planning, and obtains the best drawing path of the robot; the robot performs image drawing according to the obtained best drawing path. The present invention uses a hybrid method based on local binarization and global binarization to extract features from the source image, which is robust, reliable and accurate; aiming at the shortest total rendering time, an improved path optimization algorithm is used for region segmentation And optimal path planning, get the best drawing path of the robot, and the drawing time is shorter. The invention can be widely used in the field of image processing.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image rendering method and system for an intelligent robot. Background technique [0002] Currently intelligent robots have become a hot research topic and are used in many industrial applications such as assembly, painting and grinding. With the continuous development of intelligent robot technology and drawing technology, robot drawing technology came into being. Robotic mapping technology uses industrial robots to paint images captured by cameras. Since the robot needs to be controlled in real time based on captured images, robot mapping techniques can demonstrate the robot's intelligence in response to a changing environment. [0003] In robot drawing technology, image feature extraction and drawing path determination are the two most important steps. Among the many current image feature extraction methods, the binary feature extraction method is a more commonly used met...
