Introduction


Empower AI in Extreme Edge IoT Devices

ULTRALOW POWER AI PROCESSOR

WE1 Plus, an AI accelerator-embedded ASIC platform for ultralow power applications, is designed to develop and deploy CNN-based machine learning models on battery-powered AIoT applications.

Where state-of-the-art Edge AI applications continue to be faced with large constraints in computing power, embedded memory and power supply, Himax’s WE1 Plus ultralow power microprocessor is designed to address all these considerations. In addition, WE1 Plus is equipped with proprietary sensor interface that seamlessly links with Himax’s ultralow power AoS (Always-on Sensor) to support fast wake-up for quick sensor image capture.

WE1 Plus is now adapted to a wide range of computer vision applications that allows the digital world to interact with the real world. It has been well received in these user scenarios: automatic meter reading, object detection, people counter, smart doorbell, occupancy management, digital signage, smart video conference, gesture recognition, etc.

WE1 Plus – Best AIoT Processor on Battery Devices

Computation Optimization

Flexible and optimized computation architecture could make AIoT devices perfectly fit blooming IoT applications with intelligence. WE1 can enable IoT devices to be smart with following excellent features:

  • A programmable processor with an enhanced DSP
  • Power-efficient image and JPEG hardware accelerator for real-time motion detection, object detection, and image processing
  • Optimized SRAM size to support simultaneously ultralow power vision and voice detection

CMOS Image Sensor

Himax Imaging offers a broad array of small pixel image sensors for different camera applications and has been integrated by some of the world’s leading device manufacturers.

Always On Sensor

Class-leading ultra low power sensor operating in sub-milliwatt power range with autonomous features and super low latency operation that enables smart, battery powered Always On camera.

Image Sensors

High performance, low power RAW image sensors with programmable readout modes, integration time, gain, and black level with 10 bit data output over MIPI serial link interface.

運用Himax WiseEye 實現智慧停車與車牌辨識

1. 背景與挑戰

  • 都市停車場車位數量龐大，人工巡檢與傳統感測器維護成本高。
  • 車主常因車位不明、車牌資訊遺忘，造成尋車困難與管理效率低。
  • 即時掌握車格狀態 (在席/空位)、車牌辨識 (進出與尋車)，是智慧停車管理的核心需求。

2. 技術需求

  • 即時性：車格狀態需秒級更新，提供使用者即時的空位查詢。
  • 準確性：在各種光照、遮擋、不同車型下，仍能精準檢測。
  • 低功耗：停車場場域廣，設備須長時間運作，降低能源消耗。
  • 低維護成本：模組化部署，減少額外伺服器與網路建設。

3. Himax WiseEye 模組特色

  • FHD 高解析度影像擷取：確保車格細節與車牌清晰度。
  • 邊緣推論 (Edge AI)：支援在地運算，實現 離線車格再席偵測與車牌辨識，減少雲端依賴。
  • 超低功耗設計：適合長時間即時監測，不需高耗能 GPU。
  • 靈活整合：可透過標準介面 (UART/SPI/I²C/網路) 串接停車場管理系統。

4. 應用場景

  • 車格再席偵測：判斷每個車格是否有車，並即時回報空位數量。
  • 車牌辨識 (LPR)：記錄車格停放車輛資訊，支援車格管理。
  • 智慧尋車：車主輸入或掃描車牌號碼，即可透過系統快速定位車輛所在車格。
  • 異常監控：可擴充至偵測違規停車、倒車行為或車格長時間佔用等。
  • 事件記錄：根據畫面變動，如人、車移動拍照存檔。

5. 系統架構 (概念流程)

  • 影像擷取 → Himax WiseEye 模組拍攝停車場區域
  • AI 邊緣推論
    • 車格再席檢測 → 空位/佔用狀態更新
    • 車牌辨識 → 車牌號碼比對與紀錄
    • 資料上傳/介接 → 傳送結果至停車場管理系統或雲端平台
  • 應用端服務
  • 車位引導 (APP、看板)
  • 智慧尋車 (APP/自助機)
  • 營運管理 (後台監控與數據分析)
