Autonomous driving coordinate transformation and NuSences data set analysis
First, let’s briefly go over the coordinate transformation in the camera model. World coordinate system => Image pixel coordinate system A little concept: External parameters: Coordinate transformation between coordinate systems at different locations in physical space, involving translational alignment of the origin and rotational alignment of the coordinate axis The derivation process: Rotation matrix derivation […]
p5.js transformation operation
Introduction to this article Bringing the awkward monkey, I’m the director of the Moral Education Department In canvas, transformation is the basic function. Many libraries based on the canvas package have this function, such as “Fabric.js Transform Window”. Transformation is the ability to make global adjustments to the canvas. It can perform operations such as […]

GDI Fancy Exploration Based on C# Four: Image Zoom and Coordinate Transformation
1. Two lengthy sentences When playing with GDI, you cannot avoid images after all. Maybe at the beginning, I could try to assign the bitmap directly to the Image of the pictureBox to load the image, but it is a dead thing after all. Often when loading images, they basically have the function of zooming […]
[OpenCV implements geometric transformation of images]
Article directory Summary: OpenCV implements geometric transformation, image thresholding and smoothing of images transform summary Summary: OpenCV implements geometric transformation, image thresholding and smoothing of images There are three important topics for image processing using the OpenCV library: geometric transformations, image thresholding, and image smoothing. In the geometric transformation section, the translation, rotation, scaling and […]
Opencv C++ 6. Grayscale transformation: linear transformation, grayscale inversion, logarithmic transformation, gamma transformation, (adaptive) histogram equalization
1. Principle of grayscale transformation: The original image pixel gray value r is mapped to a gray value s through the transformation function T: s=T(r). 2. Grayscale transformation method: Linear transformation (brightness and contrast adjustment): Principle: Linear transformation is a simple method of adjusting brightness and contrast by applying a linear transformation formula to the […]
