Foreword This is the first article in the Pikachu vulnerability shooting range series~~ (it should be serialized)~~. First, let’s briefly introduce the Pikachu shooting range. This shooting range was developed by Chinese people and is purely in Chinese. If you encounter difficulties during practice, you can check the tips. There are also supporting learning videos. […]

In embedded design, for a variable storage design with only two states, how to efficiently quantify the deviation of the tracking car…
Foreword (1) In embedded programming, we often need to store data from various sensors. Most of the time sensors, such as infrared light sensors, return data that is either 0 or 1. Therefore, only one bit is needed to store it. However, many people often use char array storage, so that only one-eighth of the […]

Refined solution to the bracket matching problem and ultimate stack design: uncovering the mysteries of the largest stack and the smallest stack
Directory Bracket matching problem Minimum stack Maximum stack Max stack and min stack are two important variants of extreme stack. The max stack is used to store the maximum value of the current match, and the min stack is used to store the minimum value of the current match. Bracket matching problem Let’s take a […]
vins-mono front end (1) – image optical flow tracking
Table of Contents Preface feature_tracker_node detailed explanation Preparation img_callback() detailed explanation Foreword The vins front-end mainly includes two parts: image optical flow tracking and imu pre-integration. Optical flow tracking is mainly used to track the same map point information of two adjacent frames of images, so that the back-end can solve the pose transformation between […]
This article teaches you how to use SpireCV for pod control and target detection and tracking.
Function Overview SpireCV-SDK is an edge real-time sensing SDK library specially built for intelligent unmanned systems. It can realize pod control functions and control the drone’s camera and pod, including taking pictures, recording, streaming and other functions, and can save videos. and push streaming, as well as complete target detection, identification and tracking functions. This […]
Full link tracking implementation based on Skywalking
In the previous article “Distributed application full-link tracking implementation”, several implementation methods of distributed application full-link tracking were introduced. This article will focus on the full-link implementation based on Skywalking, including the overall architecture and basic concepts and principles of Skywalking. Skywalking environment deployment, SpringBoot and Python integrated Skywalking monitoring implementation, etc. 1. Basic introduction […]
Unexpected key(s) in state_dict: “module.backbone.bn1.num_batches_tracked“
Unexpected key(s) in state_dict: “module.backbone.bn1.num_batches_tracked” When using PyTorch for deep learning model training and inference, we often use ??state_dict?? to save and load model parameters. However, sometimes when we try to load the saved state_dict, we may encounter the error “Unexpected key(s) in state_dict” and indicate the error key name. This article explains the causes […]
