The previous article spoke about the camera's calibration of the basic knowledge of visual measurement in four coordinate systems . The following focuses on the famous Zhang Zhengyu calibration Method . => 1. Preliminary knowledge => 1.1. From p
When repairing a Seagate hard drive, if a bad channel is badly needed to be fully repaired by calling the factory calibration program, here is the difference between the full auto-calibration of the efficiency source Seagate HDD and the F-class calibration.Let's start by explaining what a full automatic calibration is:The Seagate hard drive is shipped with a full

Assuming a sampling system, the ad part can obtain the number, and the corresponding physical quantity is voltage (or other );
① If an ad Value Point xmin is calibrated at "zero" and an ad Value Point xmax is calibrated at "maximum", based on the principle that "Two Points form a straight line, we can get a st

The LM algorithm has a total of three applications in camera calibration.(1) Single-target or double-target, in the case of internal-fixation, the best external parameters are calculated. The corresponding function in OpenCV is FINDEXTRINSICCAMERAPARAMS2.(2) The best internal and external parameters are calculated when the internal and external parameters are not fixed in a single target setting. The corresponding function in OpenCV is CALIBRATECAMERA
Camera calibration is used for mechanical arm capture and so on (points on the image are mapped to three-dimensional coordinates by calibration ),
In laboratory or engineering, we often need to calculate the two-dimensional image coordinates of the captured image.
As shown in, we have such an image. We need to calculate the three-dimensional positions of the object and the manipulator so that the manipulat

From the beginning of this small series will take you to learn the use of Android monkey, we still keep as concise and clear as possible to tell everyone. Also welcome everyone has a good article submission to us, there are red envelopes reward oh. Email: [Email protected], comment submissionWhat's monkey? monkey= Monkeys?
In the field of machine vision, camera calibration is a very basic task. At present, our frequently used calibration tools are OPENCV and MATLAB.
OpenCV's Checkerboard Corner extraction API requires us to specify the horizontal points of the checkerboard in order to extract the corner points. Its main process is to take the picture two value, morphological processing, to find a number of four-sided, to eac
An hp tx2000 notebook with built-in wacom tablet and touch screen, installed with ubuntu11, requires screen calibration.

in the laboratory or engineering, we often need to calculate the two-dimensional image coordinates of the captured image to compute three-dimensional coordinates. As shown, we have such a picture. We need to calculate the three-dimensional position of the object and the manipulator so that the manipulator can grasp the object precisely.We use the Zhang Zhengyu calibration method to calibrate the internal and external parameters and calculate the corre

The last three consecutive articles were introduced in detail, very good.
Because there are no answers to some of the questions below, those are details, but you know that sometimes it's a little bit of an hour to get stuck.
Sometimes, the same picture in other people's computer to open it feels very beautiful, and on their own computer opened on the feeling that some of the worse, this is why? In fact, this is a visual experience problem, some people's computer set up a good display effect, before the operation must remember the Win7 system screen Calibration screen calibration Adjusts, you can adjust the brightness of the scr

Monkey is a command-line tool in Android that can be run in the emulator or in the actual device. It sends pseudo-random user event streams (such as key input, touch input, gesture input, etc.) to the system, enabling stress testing of the application under development. Monkey testing is a fast and effective method to test the stability and robustness of the software.
Monkey all options available on the command lineConventional--helpLists the simple usage.-VEach-V of the command line increases the level of feedback information.Level 0 (default) provides less information than startup prompts, test completion, and end results.Level 1 provides more detailed testing information, such as events sent individually to the activity.Level 2 provides more detailed setup information, such as the activity that was selected or u
