PCL extracts point cloud boundary contour-AC method, plane contour

1. Overview PCL point cloud boundary feature detection (with complete code C++)_pcl calculates point cloud feature values_McQueen_LT’s blog-CSDN blog In terms of point cloud boundary feature detection (grid model boundary feature detection is already a deterministic problem, see grid model boundary detection), there is a method in PCL for point cloud boundaries that can be […]

SpringCloud GateWay custom filter GatewayFilter and AbstractGatewayFactory

1. GatewayFilter GatewayFilter is a simple interface used to define the behavior of a gateway filter. A gateway filter is a class that implements the GatewayFilter interface and can perform certain operations when a request enters the gateway or when a response leaves the gateway. Filters can be used to modify requests or responses, log, […]

Decompress zip, tar, rar, 7z, extract pictures in tif, pdf

1. Decompression interface public interface Decompress { //curFilePreDir, if the compressed package in the compressed package has the same name as the outer folder or file, problems will occur. Adding the directory prefix of the upper layer can avoid it. public<MulpartFile> decompress(File file, String curFilePredir); } 2. The decompression class implements the Decompress interface public […]

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 […]
