Detect objects + estimate distance and direction | Source code attached
In this article, you demonstrate how to use computer vision to create an application that detects objects from voice commands, estimates the approximate distance of objects, and uses location information to improve the lives of blind people. The main goal of this project is to process real-time data, similar to wearable technologies like Meta and […]

ArcGIS API for Javascript calculates length, area, distance and buffer in different coordinate systems
ArcGIS API for Javascript has a variety of methods for calculating length, area, etc., which we often get confused. Today we will briefly review the applicable scenarios of each method. 1. Calculate the length import * as geometryEngine from ‘@arcgis/core/geometry/geometryEngine’ import * as geodesicUtils from ‘@arcgis/core/geometry/support/geodesicUtils’ /** Calculate length * @param {Geometry} geometry geometry * […]
lintcode3722 · Calculate the distance between two binary tree nodes [medium in-order traversal + find the nearest common ancestor of the two nodes]
Title https://www.lintcode.com/problem/3722 Given the root node root of a binary tree and the values p and q of two nodes in the tree, you need to calculate the distance between the two corresponding nodes of p and q in the binary tree, and add it return. The distance between two nodes in a binary tree […]
Gazebo simulates lidar for distance and intensity data collection range+intensity, reflector navigation
Setting a high value for some objects makes it possible to simulate a 2D lidar scanner to output high-intensity data containing the angles at which reflectors exist. Will this work? I want to simulate lidar in gazebo and record rosbag, but the online tutorials basically set and record the range, and cannot collect the reflection […]
