qwqwqw2088 发表于 2024-11-24 16:16 传感器的测量精度与实际值偏差比较大 可能与环境光有关系 偏差校准要扣除环境光，比如用两个测量点校 ... 我这里做的实验不够严谨，应该在黑暗条件下进行这种精度测量最好，在真正的使用中如果追求更加高的精度，还是要进行多点的线性校准； 不同的反射物体返回的信号质量是不一样，这个传感器应该也可以通过信号质量对测试精度进行部分修正和补偿

今天进行简单的精度实验测试。 由于传感器的精度和测量频率过很大关系，所以本次实验看看同一位置下、不同频率对测量精度的影响。 下面为不同频率下测距的具体数据结果图(注:匿名助手上位机有FPS统计，在图片左下角) 频率 误差 100Hz 12mm 50Hz 5mm 10Hz 4mm 5Hz 2mm 从数据来看同一目标、同一距离条件下，频率越低精度越高，后期对数据进行滤波处理的话精度会比目前高一些，在不太考虑实时性的情况下精度应该能达到2mm内，当然，测距的精度与环境光、目标属性、测量距离都有很大的关系。由于板子不是非常好固定，所以先进行本次简单的测距精度测试。从测量结果来看，与我手头上的相位式测距仪(优利德LM50A)相比,即使是在最慢频率下的测量，53L4A3精度的重复性还是不如毫米级的相位激光测距仪，但53L4A3的优势是速度可以比较快，体积很小，易于集成，总之两者的原理和应用场景还是有很大不同的。

首先感谢EEWORLD以及得捷电子给予这次测评的机会。 先了解一下VL53L4ED官方参数特性 首先运行一下官方例程，让传感器先工作起来，打开STM32CUBEMX，安装TOF扩展包 安装完成后在本地磁盘找到软件包后打开VL53L4A3的例程 例程有3个分别为多传感器测距、单传感器测距、阈值检测，由于本次测评的硬件只有1个中间传感器，所以打开第二个例程编译下载即可体验简单的测距功能。需要注意例程的波特率是460800 接下来体验一下官方的VL53L4ED_GUI软件，软件地址STSW-IMG045 - P-NUCLEO-53L4A3 pack graphical user interface (GUI) - 意法半导体STMicroelectronics 先升级STLink模式为VCP+U盘模式 然后打开VL53L4ED_GUI后点击Flash FW烧录固件等待绿灯亮起 点击开始测试 官方的软件波形图局限性能比较大，不能看更多的历史数据，还不能放大缩小，很不方便，所以接下来进行程序驱动的移植，并使用匿名助手上位机软件进行传感器的测试。 本次程序移植以官方的SimpleRangning例程为参考，并加入匿名助手的通讯协议代码，移植过程此处省略，移植后的代码结构如下 本次测试代码中使用的通讯帧是灵活格式帧（具体可以查看上位机说明书） 通讯函数定义如下 匿名助手上位机的灵活数据帧配置如下 打开数据波形控件，添加相关变量 配置完成后进行测试即可，不得不说匿名助手的波形显示功能非常的灵活方便 传感器初始化程序如下，传感器工作过程可以参考手册(UM3177)和注释 void bsp_tof_init(void) { uint32_t Id; /* reset XSHUT (XSDN) pin */ HAL_GPIO_WritePin(VL53L4A3_XSHUT_C_PORT, VL53L4A3_XSHUT_C_PIN, GPIO_PIN_RESET); HAL_Delay(2); HAL_GPIO_WritePin(VL53L4A3_XSHUT_C_PORT, VL53L4A3_XSHUT_C_PIN, GPIO_PIN_SET); HAL_Delay(2); printf("53L4A3 Simple Ranging demo application\r\n"); status = VL53L4A3_RANGING_SENSOR_Init(VL53L4A3_DEV_CENTER); if (status != BSP_ERROR_NONE) { printf("VL53L4A3_RANGING_SENSOR_Init failed\r\n"); while (1); } /*- 读取传感器ID -*/ VL53L4A3_RANGING_SENSOR_ReadID(VL53L4A3_DEV_CENTER, &Id); VL53L4A3_RANGING_SENSOR_GetCapabilities(VL53L4A3_DEV_CENTER, &Cap); /*-- 测量模式 --*/ Profile.RangingProfile = VL53L4ED_PROFILE_CONTINUOUS; /*-- 测量时间 10 ms < TimingBudget < 200 ms --*/ Profile.TimingBudget = TIMING_BUDGET; Profile.Frequency = 0; /* Induces intermeasurement period, NOT USED for normal ranging */ /*-- 测量噪声输出使能 --*/ Profile.EnableAmbient = 1; /* Enable: 1, Disable: 0 */ /*-- 测量信号强度输出使能 --*/ Profile.EnableSignal = 1; /* Enable: 1, Disable: 0 */ /* set the profile if different from default one */ VL53L4A3_RANGING_SENSOR_ConfigProfile(VL53L4A3_DEV_CENTER, &Profile); /* 阻塞模式 */ // status = VL53L4A3_RANGING_SENSOR_Start(VL53L4A3_DEV_CENTER, RS_MODE_BLOCKING_CONTINUOUS); /* 同步模式 */ status = VL53L4A3_RANGING_SENSOR_Start(VL53L4A3_DEV_CENTER, RS_MODE_ASYNC_CONTINUOUS); if (status != BSP_ERROR_NONE) { printf("VL53L4A3_RANGING_SENSOR_Start failed\r\n"); while (1); } }   Main函数 int main(void) { int32_t i = 0, status; RANGING_SENSOR_Result_t Result; bsp_init(); init_cycle_counter(true); bsp_tof_init(); while(1) { // int64_t time_stamp = get_system_ms(); VL53L4A3_RANGING_SENSOR_GetDistance(VL53L4A3_DEV_CENTER, &Result); /* polling mode status = */ while(ToF_EventDetected == 0) { } // printf("time_stamp = %lldms\r\n", get_system_ms() - time_stamp); ToF_EventDetected = 0; ano_send_custom1(Result.ZoneResult[0].Distance[0], Result.ZoneResult[0].Status[0], Result.ZoneResult[0].Ambient[0], Result.ZoneResult[0].Signal[0]); } }   在程序中我们可以通过TIMING_BUDGET参数进行测量时间的设定，其中10 ms < TimingBudget < 200 ms 通过VL53L4A3_RANGING_SENSOR_Start()函数设置模式，有四种模式可选(如下)，前两个是阻塞模式，后面两个是中断模式 通过RANGING_SENSOR_INSTANCES_NBR可以配种传感器的个数，例程中配置的是3，即默认为3个传感器，本次测评板只有1个，为了节约内存我们可以定义为1，但VL53L4A3_DEV_CENTER需要重新定义为0 接下来进行精度等方面的测试。

发表了主题帖： 《智能驾驶之激光雷达算法详解》5.多传感器SLAM

本书第13章是关于多传感器融合SLAM算法的相关讲解，主要介绍了多传感器融合在智能车辆定位中的应用。由于单一传感器存在工作特性和局限性，处理不了复杂路况，因此多传感器融合实现高精度、稳定、实时的定位成为学术界和工业界的热点之一。多传感器融合 SLAM 有松耦合和紧耦合两种方式，紧耦合方式精度和稳定性较高，是目前研究重点，如 LIC-Fusion 算法、基于因子图框架的算法、R2LIVE 算法及 LVI-SAM 算法等。此外，一些学者结合事先构建的高精点云地图提供全局定位信息，如百度的相关研究及图森未来的研究。 本章主要讲解了视觉、激光雷达、IMU融合的R2LIVE 算法和融合点云地图的TMFL算法。其中R2LIVE 算法由里程计模块和因子图优化模块两部分组成。里程计模块基于迭代误差状态卡尔曼滤波框架实现激光雷达、相机和 IMU 三种观测数据紧耦合，得到系统位姿状态初步估计并按各自传感器频率输出。该框架采用误差状态卡尔曼滤波器思想在误差状态空间进行状态传播，结合迭代误差状态卡尔曼滤波器更新方式，转换为最大化后验估计问题并用高斯牛顿法求解。在激光雷达侧位姿初步估计时使用基于平面特征点提取和运动补偿的方法；在相机侧位姿初步估计时使用快速角点提取和 KLT 光流跟踪的方式。因子图优化模块使用基于动态滑窗的因子图方法实现对视觉路标、关键帧位姿以及相机相对激光雷达和 IMU 时间偏差的优化。 在 L4 级智能驾驶任务中，为保证定位算法的精度、实时性和鲁棒性，一些学者考虑引入高精地图实现长距离绝对定位。图森未来的 L. Pan 等在 ICRA 2021 会议上提出基于激光雷达特征地图辅助的多传感器紧耦合定位（TMFL）算法，该算法基于因子图优化框架实现 IMU、轮速计与激光点云地图之间的紧耦合，将车辆位姿估计问题转化为优化问题，用固定延迟平滑方式在动态滑窗内求解。在 TMFL 算法中，当前帧激光点云和激光雷达特征地图的匹配实现全局位姿估计，基于车辆运动学模型和 IMU / 轮速计数据得到局部相对位姿变化，二者联合构成对车辆状态的最终约束。 其中R2LIVE 算法在github中有开源代码可以供查阅: https://github.com/hku-mars/r2live

IMU惯性测量单元目前是无人机、机器人、汽车领域等常用的测量运行状态的传感器，主要包含加速度计和陀螺仪，通过各种融合算法如互补滤波、卡尔曼滤波等计算车辆的实时姿态，但IMU在航向角存在积分误差，而激光里程计主要通过对环境的感知来来实现对自身的定位估计，通过激光里程计和IMU的互补性进行车辆的组合实时精确姿态计算。 根据组合方式和原理业界通常将LiDAR+IMU分为松耦合和紧耦合两个方向。LiDAR+IMU松耦合定位算法通常使激光里程计和IMU航位推算相互独立运行，并基于卡尔曼滤波框架、粒子滤波框架等实现二者信息的融合，最终输出定位估计结果。LiDAR+IMU紧耦合定位算法为对同一姿态优化问题结合激光雷达数据和IMU数据来求解。 <智能驾驶之激光雷达算法详解>中提到的具有代表性的组合定位算法有IMU-AHFLO算法和LIO-SAM算法。IMU-AHFLO算法相对比较简单，书中的推导非常的详尽，非常具有学习价值。 LIO-SAM算法书中也有详细的推导，感兴趣的小伙伴可以自己查阅研究一下。 LiDAR与IMU组合定位的松耦合和紧耦合两种技术路线各有优势，松耦合计算相对简单，但伴随着IMU的累计误差还是会导致算法精度降低；紧耦合方式通过基于因子图优化、IMU预积分等方法实现LiDAR和IMU的紧耦合，进而实现鲁棒、精确的融合定位。

发表了主题帖： 《智能驾驶之激光雷达算法详解》3.基于3D激光点云的目标检测

基于激光雷达3D点云的目标检测、多目标跟踪等算法是利用深度学习相关算法进行解决相应问题的，本书的第七章对深度学习进行了基础的讲解，主要是人工神经网络、卷积神经网络、ViT模型等进行了介绍，对于我这种深度学习小白来说，无疑撬开了我对深度学习相关基础的认知,。 激光点云的3D目标检测通常是指在点云中识别车辆、行人等目标，并给出其尺寸、位置和朝向等信息。雷达目标检测的分类方法如下所示: 本书介绍的常用的具有代表性的3D目标检测算法有MLP架构的PointNET网络算法、PointNET++网络算法、PointRCNN网络算法、基于体素的VoxelNet网络算法、PointPillars网络算法、基于深度图的RangeDet网络算法、多视角特征融合的MVF网络算法等。 每种算法有各自的优势和不足，例如: PointRCNN网络是将基于原始点云进行特征提取的方式嵌入二阶段检测架构的一次成功尝试，且该网络模型背后的将车辆位置和朝向问题等效为“分类+回归”问题的思想也被后续许多算法借鉴。但是该网络模型的流程相对比较复杂，在KITTI数据集中，该网络模型对每帧点云进行推理的耗时为0.1秒左右，较难达到实时性要求。 VoxelNet网络结构清晰，且检测性能也有较大提升，然而，由于其引入了3D卷积，VoxelNet 网络模型的推理速度较慢，很难满足智能驾驶感知模块的实时性要求。而PointPillars网络却有较好的实时性和检测性能。 总之，通过对个网络算法的公式、原理推导和图形化说明，让我对这些深度学习网络算法及在3D激光点云的应用有了了解和认识。

本书的第三章、第四章是对标定算法的讲解，第三章着重讲解了激光雷达相对于车体的外参标定算法，将激光雷达外参算法初步分为了三类，①基于道路、标定物特征的雷达动态外参标定。②基于手眼模型的雷达外参标定③基于积累点云特征化的雷达外参标定算法。本章对分别这三个方向选取了比较有代表性的算法分析，如SSAC算法、使用Navy算法求解手眼模型、AESC-MMS算法、DyLESC算法等，让我了解了各算法的原理、概念、流程、公式推导。 第四章是基于激光雷达和相机数据相互融合的外参标定算法的讲解，基于激光雷达数据和相机视觉数据的强互补性进行精确的外参标定，3D雷达和2D相机之间的外参标定分类如下 本章分析的具有代表性的算法分别时基于标定物的L-C静态标定-ILCC算法、无标定物的L-C静态标定-PESC算法、无标定物的L-C动态在线标定-AOCCL算法。总的来说，静态、有标定物的离线标定方法通常可在高精度的标定件中使用；而动态、无标定物的在线标定方法可在自然驾驶场景中使用，并根据离线标定的结果、车辆运动等信息， 实现对离线标定结果的全部参数或部分参数的修正。

发表了主题帖： 【瑞萨RA8D1开发板，基于M85内核的图形MCU测评】3.RGB-LCD

由于LVGL不支持RGB666，触摸的I2C和j-link串口冲突，所以上个贴子中的硬件设计需要重新设计一下 在移植LVGL之前首先进行RGB LCD驱动的编写,本次实验所用屏幕为反客4.3寸800*480分辨率RGB屏幕 本次实验实在点灯工程的基础上进行的，由于实验设置的屏幕色彩模式为RGB565，并采用双缓存，所以内部RAM空间不足，需要使用外部SDRAM，先进行外部SDRAM的驱动配置，此处参考官方程序即可，下面为IO配置 Sdram文件添加到工程中 接下来进行GLCDC接口的时钟配置 然后进行GLCDC的IO口设置，色彩模式RGB565 Stacks添加GLCDC 设置属性 添加LCD背光的PWM驱动 配置完成后点击代码生成，在工程中添加LCD驱动的。下面为部分驱动代码 static uint16_t *lcd_current_working_buffer = (uint16_t *) &fb_background[0]; static uint8_t lcd_framebuffer[LCD_BUF_SIZE] BSP_ALIGN_VARIABLE(64) BSP_PLACE_IN_SECTION(".sdram"); static void bsp_lcd_backlight_init(void); /** * [url=home.php?mod=space&uid=159083]@brief[/url] 初始化 * * @param 无 * @retval 无 */ void bsp_lcd_init (void) { fsp_err_t err; // Open the GLCDC driver err = R_GLCDC_Open(&g_display0_ctrl, &g_display0_cfg); //printf("err1 %d\r\n",err); err = R_GLCDC_Start(&g_display0_ctrl); //printf("err2 %d\r\n",err); bsp_lcd_backlight_init(); } /** * @brief 初始化 * * @param 无 * @retval 无 */ static void bsp_lcd_backlight_init(void) { /* 初始化 GPT 模块 */ R_GPT_Open(&g_timer_gpt6_ctrl, &g_timer_gpt6_cfg); /* 启动 GPT 定时器 */ R_GPT_Start(&g_timer_gpt6_ctrl); /* 重新设置占空比为 80% */ lcd_set_brightness(100); } /** 自定义函数：设置PWM占空比 @param duty 占空比范围：0~100 % */ void lcd_set_brightness(uint8_t duty) { timer_info_t info; uint32_t current_period_counts; uint32_t duty_cycle_counts; if (duty > 100) duty = 100; //限制占空比范围：0~100 /* 获得GPT的信息 */ R_GPT_InfoGet(&g_timer_gpt6_ctrl, &info); /* 获得计时器一个周期需要的计数次数 */ current_period_counts = info.period_counts; /* 根据占空比和一个周期的计数次数计算GTCCR寄存器的值 */ duty_cycle_counts = (uint32_t)(((uint64_t) current_period_counts * duty) / 100); /* 最后调用FSP库函数设置占空比 */ R_GPT_DutyCycleSet(&g_timer_gpt6_ctrl, duty_cycle_counts, GPT_IO_PIN_GTIOCA); } /** * @brief 设置显示缓存 * @param index:缓存区索引 1.第一缓存数组 2.第二缓存数组 * @retval 无 */ static void lcd_set_display_buffer(uint8_t index) { /* 更改图层的帧缓冲区指针 */ R_GLCDC_BufferChange(&g_display0_ctrl, (uint8_t*)fb_background[index - 1], DISPLAY_FRAME_LAYER_1); } /** * @brief 设置当前使用的缓存 * @param index:缓存区索引 1.第一缓存数组 2.第二缓存数组 * @retval 无 */ static void lcd_set_working_buffer(uint8_t index) { if (index >= 1 && index <= 2) { lcd_current_working_buffer = (uint16_t *)fb_background[index - 1]; } } ///** // * @brief 使能双buffer // * @retval 无 // */ //static void lcd_enable_double_buffer(void) //{ // lcd_set_working_buffer(1); // lcd_set_display_buffer(1); //} /** * @brief lcd清屏 * @param color:RGB565 颜色 * @retval 无 */ void lcd_clear(uint16_t color) { for (uint32_t i = 0; i < (LCD_WIDTH * LCD_HEIGHT); i++) { lcd_current_working_buffer[i] = color; } } /** * @brief lcd切换帧缓冲区 * @retval 无 */ void lcd_swap_buffer(void) { if (lcd_current_working_buffer == (uint16_t *)fb_background[0]) { lcd_set_working_buffer(2); lcd_set_display_buffer(2); } else { lcd_set_working_buffer(1); lcd_set_display_buffer(1); } } /** * @brief lcd清平 * @param color:RGB565 颜色 * @retval 无 */ void lcd_draw_pixel(uint32_t x, uint32_t y, uint16_t color) { // Verify pixel is within LCD range if ((x <= LCD_WIDTH) && (y <= LCD_HEIGHT)) { switch (g_screen_rotation) { case ROTATION_ZERO: { lcd_current_working_buffer[(y * LCD_WIDTH) + x] = color; break; } case ROTATION_180: { lcd_current_working_buffer[((LCD_HEIGHT - y) * LCD_WIDTH) + (LCD_WIDTH - x)] = color; break; } default: { lcd_current_working_buffer[(y * LCD_WIDTH) + x] = color; break; } } } else { printf("draw pixel outof range:%d,%d", x, y); } } /** * @brief 填充数组 * @param x_start: * @param y_start: * @param x_end: * @param y_end: * @param pcolor: * @retval 无 */ void lcd_fill_array(uint16_t x_start, uint16_t y_start, uint16_t x_end, uint16_t y_end, void *pcolor) { uint16_t *pixel = NULL; uint16_t cycle_y, x_offset = 0; pixel = (uint16_t *)pcolor; for (cycle_y = y_start; cycle_y <= y_end;) { for (x_offset = 0; x_start + x_offset <= x_end; x_offset++) { lcd_draw_pixel(x_start + x_offset, cycle_y, *pixel++); } cycle_y++; } } void lcd_fill_rectangle(uint16_t x_start, uint16_t y_start, uint16_t x_end, uint16_t y_end, uint16_t pixcolor) { uint16_t cycle_y, x_offset = 0; for (cycle_y = y_start; cycle_y <= y_end;) { for (x_offset = 0; x_start + x_offset <= x_end; x_offset++) { lcd_draw_pixel(x_start + x_offset, cycle_y, pixcolor); } cycle_y++; } }   在LED线程中测试一下 void led_thread_entry(void* pvParameters) { FSP_PARAMETER_NOT_USED(pvParameters); bsp_dwt_init(); bsp_led_init(); bsp_uart3_init(); bsp_sdram_init(); bsp_lcd_init(); lcd_clear(BLACK); lcd_fill_rectangle(100,100,200,400,RED); lcd_fill_rectangle(200,100,300,400,GREEN); lcd_fill_rectangle(300,100,400,400,BLUE); while(1) { led_toggle(); vTaskDelay(20); } }   拍照有些失真，屏幕的实际观感效果还是很不错的。下一步移植LVGL_V9.1
