A few days ago bought a micro-vision V411 acquisition card, initially want to use OPENCV to directly collect video stream, using the teacher's multi-camera acquisition program. Unfortunately, no image is collected, simply use the SDK provided by micro-vision to develop. SDK Scenario One: Mv_capturesingle Dcardnum = Mv_getdevicenumber () HWND Hwnd=getsafehwnd (); DWORD i; for (i=0;iThis line is

experience? Precisely because the concept of user experience is virtual, intangible, then the seoer are crazy to do? The answer, the seoer. Visible SEO1.0 and 2.0 times, a lot of seoer reduced to SEO migrant workers (of course, there are some more flexible brain people embarked on the Black Hat seo "no way"). And the SEO3.0 era is not just rely on a "crazy" can change the era of harvest, although the search engine in the user experience of the algorithm technology is not perfect, but this is a

The study of binocular vision has been a certain time, but always feel very vague, especially in the specific algorithm, so want to seriously study the calibration of the principle of matching and the implementation of the program, welcome to criticize correct, to start from the principle and then the program to achieve. From the definition, the camera calibration is essentially a process of determining the internal and external parameters of the cam

Machine Vision Learning Notes (8)--Bouguet stereo correction based on OPENCV In Machine Vision Learning notes (7)--based on OPENCV's binocular camera calibration, we have calculated the Matrix R and T, which describes the relationship of two {camera} coordinate systems, and the stereo correction is mainly the function of these two parameters. Binocular camera System is the main task is ranging, and paral

Sobel operator of approximate derivative Sobel operators are similar to Prewitt, but they are better than Prewitt operators.The Sobel operator in the x direction isThe Sobel operator in the y direction isThe

In the previous article, we explained the edge gradient computing function. This article describes the image pyramid. Image pyramid is widely used in computer vision applications. Image pyramid is an image set, all the images in the set are derived from the same original image and obtained through continuous downsampling of the original image. Preface In the previous article, we explained the edge gradient computing function. This article is about im

ObjectiveIn the field of computer vision CV, visual tracking is one of the important sub-problems. From my point of view, visual tracking is used on robots, on mobile devices, so why not put some tracking algorithms on the iphone to see the actual tracking effect. This is the most realistic comparison, the use of some video is not practical, and the key is not very good comparison of real-time. For mobile devices, real-time is the most important thing

Enterprises should have a hard saying "goal". We hear more and more-but what does that mean? Isn't there enough labels to describe the enterprise's direction? Do we need another tag? I think we need it, and I have summarized clustering to help distinguish all these labels. What is an image saying that a company wants to become in the future? This is typically illustrated by advanced management, and is accomplished by working hard to think about things outside of everyday activities in a clear an

The Lego stalls are so big that they need money in different directions to support their strategic direction across smart hardware (from TV to car), film and television (f

I recently read Du Lala's title escalation and recommended this book to you in my spare time. Here we will copy a section in the book "Realizing the ideal of retirement as soon as possible-you need your vision and qualifications" to share with you. How can I find a good position? First, you have to understand what kind of job is a good job. Then, you have to make yourself qualified to seek that job. 1. What kind of job is a good job. 1. You h

I just read a blog post about the startup story of Jing zhixun, president of sanyang Motor Co., Ltd.. one of the stories is about Song Xixing (originally, Jing zhixun was from Panasonic) the story of improving bicycle lights. At that time, Mr. Panasonic proposed the following requirements for new bicycle lights:Bright, durable, no flameout in the middle, inexpensive, easy to use.This is a very good example of a product vision. He did not describe the

In the past, problems occurred during binocular vision transplantation:Http://blog.csdn.net/b5w2p0/article/details/39101499It is a problem with the right camera to correct the image, and the left camera is normal.I tried the following methods to solve the problem:1. Camera hardware adjustment, high and low, according to the image2. apply different cvstereovision or CV: stereovision, which is the correction and remap functions of the C and C ++ interfa

On the last point, the core task of robot vision is estimation, and the theoretical framework is projective geometry theory. The great power of the single-should transform was demonstrated in previous assignments. However, the first condition of the entire estimation is the known pixel coordinates, especially the pixel coordinates of the corresponding points in multiple graphs.Single image processing methods are da Lu Huo, do not repeat.

From http://blog.csdn.net/jtop0/article/details/6167432Typically, CMake is the Engineering building tool for cross-platform software development and maintenance processes. "Build your project on every system without caring about how to create executable files and dynamic libraries."CMake compared to other similar tools (shell scripts, makefiles, jam files, projects based on complex scripts like autoconf and Automake), CMake makes less assumptions about the underlying system. CMake is implemented

According to foreign media reports, researchers at MIT earlier this year reported that the human brain has an amazing ability to identify or dispose of an image in a short period of 13 milliseconds. This is much faster than the previous study. Previous studies have suggested that the brain's time to identify or dispose of an image is about 80 milliseconds to 100 milliseconds. These latest findings suggest that vision will be able to consume "facts" mo

Key detection is often required and feature extraction together, the key point of the detection of an important property is rotational invariance, that is, the object can be rotated to detect the corresponding key points. But honestly, I think this requirement is a bit of a chicken's eye for robot vision. Because the three-dimensional point cloud that the robot collects is not a complete object, no camera has the perspective function. The point cloud
