指令调用d435i录制并保存

您可以使用以下代码调用D435i相机录制并保存视频。同样，您需要安装相应的SDK并在代码中引用它。

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)

# Start streaming
pipeline.start(config)

# Define codec and create VideoWriter object
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('output.avi', fourcc, 30.0, (640, 480))

# Record video for 10 seconds
start_time = time.time()
while time.time() - start_time < 10:
    # Wait for a coherent pair of frames: depth and color
    frames = pipeline.wait_for_frames()
    depth_frame = frames.get_depth_frame()
    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())

    # Apply colormap on depth image (image must be converted to 8-bit per pixel first)
    depth_colormap = cv2.applyColorMap(cv2.convertScaleAbs(depth_image, alpha=0.03), cv2.COLORMAP_JET)

    # Write frames to video
    out.write(color_image)

# Stop streaming
pipeline.stop()
out.release()

在上面的代码中，我们定义了一个 VideoWriter 对象来保存录制的视频。我们等待相机捕获一组深度和彩色帧，并将它们转换为 numpy 数组。然后，我们对深度图像应用了伪彩色映射，然后将彩色图像写入视频。我们记录了10秒的视频，并在结束后停止了相机流式传输并释放视频写入器。
