1. 本研究利用 PCA 对可见-近红外（450～1 000 nm）、可见光（450～780 nm）和近红外（780～1 000 nm）光谱区域的苹果高光谱图像数据进行降维，获得 PC 图像，通过对 PC 图像进行分析，确定可用于分割损伤和正常区域的有效光谱区域，对比分析几个光谱区域的 PCA 的效果。(but currently no practical system for detecting blood spots and dirt stains exists. In order to obtain maximum throughput, processing speeds of over 85,000 eggs per hour are common. The demanding requirements placed on the human workers result in two types of grading errors)

单片机驱动的OLED显示屏，单色绿光。C语言(Single-chip-driven OLED display, monochrome green. C language)

基于STM32F4的四轴航拍平台。以STM32F407为控制核心，四轴飞行器为载体，辅以云台的航拍系统。硬件上由飞控电路，电源管理，通信模块，动力系统，机架，云台伺服系统组成。算法上采用简洁稳定的四元数加互补滤波作为姿态解算算法，PID作为控制器，实现飞行，云台增稳等功能(Four axis aerial platform based on STM32F4. Taking STM32F407 as the control core, the four axis flying vehicle as the carrier, and the aerial camera system with ptz. The hardware is composed of flight control circuit, power management module, communication module, power system, frame and PTZ servo system. The algorithm uses a simple and stable four yuan number plus complementary filtering as the attitude calculation algorithm, and PID is used as a controller to achieve flight, PTZ stability, and other functions)
