xby-helmet-head: Safety Helmet and Human Detection Plugin

xby-helmet-head is an industrial safety detection plugin based on DeepSeek Harness (DSH), designed to identify human bodies, heads, and safety helmets. By wrapping the API of the official XiaoBenYang website, it supports three input methods: image URLs, BASE64 strings, and local file paths. It outputs bounding boxes, confidence scores, and labels. Users need to register to obtain an API key and configure it using `set_xby_apikey`, then call the corresponding interface to perform detection. This plugin is suitable for automated inspection and safety compliance checking scenarios, abstracting away the complexity of the underlying inference.
