assertion "bayerId && statsId" failed in tryRunPipeline() #293
Description
I have a RPi 5 and a Picamera 2 and using rospy, the camera works but after a few seconds/minutes I get the error:
assertion "bayerId && statsId" failed in tryRunPipeline()
my python code is as follows:
#!/usr/bin/env python3
import rospy
from sensor_msgs.msg import CompressedImage
from abstract_node import AbstractNode
import numpy as np
import cv2
from picamera2 import Picamera2
class VideoCameraNode(AbstractNode):
def init(self):
super().init('fish_camera', 'Fish camera')
self.camera_pub = rospy.Publisher('fish_camera/image', CompressedImage, queue_size=1)
self.camera_capture = Picamera2()
config = self.camera_capture.create_preview_configuration(
main={"size": (2464, 2464), "format": "BGR888"}
)
self.camera_capture.configure(config)
self.camera_capture.start()
self.__new_size = (640, 640)
self.msg = CompressedImage()
rospy.on_shutdown(self.__on_shutdown)
def run(self):
rate = rospy.Rate(20)
while not rospy.is_shutdown():
frame = self.camera_capture.capture_array("main")
frame = cv2.resize(frame, self.__new_size, interpolation=cv2.INTER_AREA)
frame = np.rot90(frame, k=3)
success, buf = cv2.imencode('.jpg', frame, [int(cv2.IMWRITE_JPEG_QUALITY), 80])
self.msg.data = buf.tobytes() if success else b''
self.camera_pub.publish(self.msg)
rate.sleep()
def __on_shutdown(self):
self.loginfo("Shutting down camera")
try:
self.camera_capture.stop()
except Exception:
pass
if name == "main":
rospy.init_node('video_camera_node')
cam_handler = VideoCameraNode()
cam_handler.run()
rospy.spin()
