简介： 在Jetson Nano上编译 pyrealsense2库包，并在Intel的tof相机上进行测试

1 编译librealsense中python相关的库

1、创建build目录

mkdir build

注意：

build目录是在librealsense目录下创建的

2、进入build目录

cd build

3、cmake

cmake ../ -DBUILD_PYTHON_BINDINGS:bool=true -DPYTHON_EXECUTABLE=/usr/bin/python3

zhihui@zhihui-desktop:~/librealsense/build$ cmake ../ -DBUILD_PYTHON_BINDINGS:bool=true -DPYTHON_EXECUTABLE=/usr/bin/python3
-- Checking internet connection...
-- Failed to identify Internet connection
CMake Warning at CMakeLists.txt:16 (message):
  No internet connection, disabling BUILD_WITH_TM2


CMake Warning at CMakeLists.txt:22 (message):
  No internet connection, disabling IMPORT_DEPTH_CAM_FW


-- Info: REALSENSE_VERSION_STRING=2.41.0
-- Setting Unix configurations
-- using RS2_USE_V4L2_BACKEND
-- pybind11 v2.2.1
-- Could NOT find apriltag (missing: APRILTAG_INC APRILTAG_LIB) 
-- Unable to find apriltag library, skipping pose-apriltag example
-- Configuring done
-- Generating done
-- Build files have been written to: /home/zhihui/librealsense/build
zhihui@zhihui-desktop:~/librealsense/build$

注意：

  • 在cmake的时候最好把网断掉，要不在编译的时候可能会检测网络是否连接，会很慢
  • 如果不指定，默认是生成python2的动态库，这里我们指定为python3：-DPYTHON_EXECUTABLE=/usr/bin/python3

纠正一下：

一定要联网，一定要联网，一定要联网，在cmke的时候，会去克隆github上的pybind11仓库，大小大概9MB，因此必须联网，耐心等待一下即可！

4、make编译

make -j3

这个编译会久一点，大概半个小时左右，耐心等一下！

zhihui@zhihui-desktop:~/librealsense/build$ make -j3

zhihui@zhihui-desktop:~/librealsense/build$

编译完成之后，你会在：/usr/local/lib下发现编译生成的librealsense2动态库文件

zhihui@zhihui-desktop:/usr/local/lib$ ls
cmake       librealsense2-gl.so       librealsense2-gl.so.2.41.0  librealsense2.so.2.41    librealsense-file.a  python2.7
libglfw3.a  librealsense2-gl.so.2.41  librealsense2.so            librealsense2.so.2.41.0  pkgconfig            python3.6
zhihui@zhihui-desktop:/usr/local/lib$

image.png

同时在python3的库包存放位置/usr/local/lib/python3.6/pyrealsense2，你也会看到生成的pyrealsense2相关的动态库文件

zhihui@zhihui-desktop:/usr/local/lib/python3.6/pyrealsense2$ ls
pybackend2.cpython-36m-aarch64-linux-gnu.so    pybackend2.cpython-36m-aarch64-linux-gnu.so.2.41.0  pyrealsense2.cpython-36m-aarch64-linux-gnu.so.2.41
pybackend2.cpython-36m-aarch64-linux-gnu.so.2  pyrealsense2.cpython-36m-aarch64-linux-gnu.so       pyrealsense2.cpython-36m-aarch64-linux-gnu.so.2.41.0
zhihui@zhihui-desktop:/usr/local/lib/python3.6/pyrealsense2$ ^C

image.png

zhihui@zhihui-desktop:/usr/local/lib/python3.6/pyrealsense2$ ls
pybackend2.cpython-36m-aarch64-linux-gnu.so    pybackend2.cpython-36m-aarch64-linux-gnu.so.2.41.0  pyrealsense2.cpython-36m-aarch64-linux-gnu.so.2.41
pybackend2.cpython-36m-aarch64-linux-gnu.so.2  pyrealsense2.cpython-36m-aarch64-linux-gnu.so       pyrealsense2.cpython-36m-aarch64-linux-gnu.so.2.41.0
zhihui@zhihui-desktop:/usr/local/lib/python3.6/pyrealsense2$

但是，此时如果你在命令行中导入pyrealsense2，虽然可以正确导入，但是并没有任何接口可以使用

zhihui@zhihui-desktop:~$ python3
Python 3.6.9 (default, Oct  8 2020, 12:12:24) 
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyrealsense2 as rs
>>> dir(rs)
['__doc__', '__loader__', '__name__', '__package__', '__path__', '__spec__']
>>>

6、添加动态库相关环境变量

vim ~/.bashrc

export PYTHONPATH=$PYTHONPATH:/usr/local/lib:/usr/local/lib/python3.6/pyrealsense2

再次导入pyrealsense2可以成功运行编译的库包

zhihui@zhihui-desktop:~$ python3

2 使用pyrealsense2获取Intel 的tof相机视频流用例

import pyrealsense2 as rs
import numpy as np
import cv2

# Configure depth and color streams
pipeline = rs.pipeline()
config = rs.config()
# config.enable_stream(rs.stream.depth, 640, 480, rs.format.z16, 30)
# config.enable_stream(rs.stream.color, 640, 480, rs.format.bgr8, 30)

config.enable_stream(rs.stream.depth, 640, 480, rs.format.z16, 30)
config.enable_stream(rs.stream.color, 640, 480, rs.format.bgr8, 30)

# Start streaming
pipeline.start(config)

try:
    while True:

        # Wait for a coherent pair of frames: depth and color
        frames = pipeline.wait_for_frames()
        # 深度图
        depth_frame = frames.get_depth_frame()
        # 正常读取的视频流
        color_frame = frames.get_color_frame()
        if not depth_frame or not color_frame:
            continue

        # Convert images to numpy arrays
        depth_image = np.asanyarray(depth_frame.get_data())
        color_image = np.asanyarray(color_frame.get_data())
        # print(f"depth_image shape: {depth_image.shape} color_image shape: {color_image.shape}")
        print(f"depth_image value: {depth_image}")   # 里面0值很多，还有很多1900左右的值      300mm 单位是毫米=30厘米=0.3米
        # depth_image shape: (480, 640) color_image shape: (480, 640, 3)
        # 深度图是单通道  颜色图是三通道的

        # Apply colormap on depth image (image must be converted to 8-bit per pixel first)
        # 在深度图像上应用colormap(图像必须先转换为每像素8位)
        depth_colormap = cv2.applyColorMap(cv2.convertScaleAbs(depth_image, alpha=0.03), cv2.COLORMAP_JET)

        # Stack both images horizontally
        images = np.hstack((color_image, depth_colormap))

        # Show images
        cv2.namedWindow('RealSense', cv2.WINDOW_AUTOSIZE)
        cv2.imshow('RealSense', images)
        cv2.waitKey(1)

finally:

    # Stop streaming
    pipeline.stop()

通过定时器实现视频流，用while循环获取视频流的方式，是第一帧获取完之后，立马去获取第二帧，这种方式会很消耗CPU资源，因此通过定时器获取视频流可以解决资源！
