1.Hand-eye calibration so-calledhand-eye system, that is, when the human eye sees something and wants the hand to grab it, the brain needs to know the coordinate relationship between the eye and the hand. The camera knows the pixel coordinates, and the robot knows the spatial coordinate system, so hand-eye calibration is to obtain the coordinate transformation relationship between the pixel coordi... »

OpenCV is a cross-platform computer vision library released under the BSD license (open source). It can run on operating systems such as Linux, Windows, Android and Mac OS. OpenCV was originally composed of a series of C functions and a small number of C++ classes. It also provides interfaces in other languages such as Python. It implements many general algorithms in image processing and compute... »
Canny edge detection Canny edge detection is a method of detecting edges using a multi-level edge detection algorithm. In 1986, John F. Canny publishedThe famous paper A Computational Approach to Edge Detection is presented, which details how to perform edge detection.detection. Canny() edge detection step Canny edge detection is divided into the following steps:Step 1: Denoise. Noise will affect ... »
