* feat: Wake up when a person is detected * fix: Solve the problem of no sound when using WakeWordInvoke * fix: Solve the problem of triggering dialogue when the person has not left * feat(vision): 优化视觉检测逻辑并增加配置接口 本次提交旨在优化视觉检测功能,使其行为更自然、更智能,并为用户提供灵活的配置选项。 主要更新包括: 1. 引入了更精细的检测状态机: - IDLE: 空闲状态,等待检测目标。 - VALIDATING: 验证状态,在检测到目标后,持续一段时间(可配置)以确认其存在,防止误触发。 - COOLDOWN: 冷却状态,在一次成功交互后进入,避免过于频繁的打扰。 2. 新增了用于配置视觉检测的 MCP 工具: - self.vision.get_detection_config: 获取当前的检测参数(阈值、冷却间隔、验证时长、目标类型)。 - self.vision.set_detection_config: 允许用户动态修改这些参数,以适应不同场景。 3. 性能优化: - 增加了配置参数的内存缓存,避免了在检测循环中对 NVS 的频繁访问。 * feat: Inference using Model 4 * feat: default inference disable * feat: version cmd change to output json * fix: fix image display * Fix include directives for esp_check and esp_app_desc --------- Co-authored-by: Spencer <love4yzp@gmail.com> Co-authored-by: Xiaoxia <terrence@tenclass.com>
