python - TypeError : mat data type = 17 is not supported, 使用 realsense d435 显示红外数据

Question

我目前正在使用 d435，我想按照我的代码显示红外图像(左侧和右侧，但目前只关注一个):

import pyrealsense2 as rs
import numpy as np
import cv2

# We want the points object to be persistent so we can display the 
#last cloud when a frame drops
points = rs.points()

# Create a pipeline
pipeline = rs.pipeline()
#Create a config and configure the pipeline to stream
config = rs.config()
config.enable_stream(rs.stream.infrared, 1, 1280, 720, rs.format.y8, 30)
# Start streaming
profile = pipeline.start(config)

# Streaming loop
try:
    while True:
        # Get frameset of color and depth
        frames = pipeline.wait_for_frames()
        ir1_frame = frames.get_infrared_frame(1) # Left IR Camera, it allows 1, 2 or no input
        image = np.asanyarray(ir1_frame)
        cv2.namedWindow('IR Example', cv2.WINDOW_AUTOSIZE)
        cv2.imshow('IR Example', image)
        key = cv2.waitKey(1)
        # Press esc or 'q' to close the image window
        if key & 0xFF == ord('q') or key == 27:
            cv2.destroyAllWindows()
            break
finally:
    pipeline.stop()

一切正常，直到下线:

cv2.imshow('IR Example', image)

我得到错误:

TypeError: mat data type = 17 is not supported

我找到了这个链接: TypeError: src data type = 17 is not supported

但我仍然不知道如何显示我的图像。有没有人有一些想法？请分享，我是 opencv 的新手。

image.shape = ()
image.dtype = dtype('O')

干杯

Answer 1

您需要调用 get_data() 来从帧中获取图像。

image = np.asanyarray(ir1_frame.get_data())
