The python script that I'm running becomes significantly slower when I try to write images and data using cv2.imwrite(twice-for raw image and segmented images) and numpy.savetxt respectively.
The other possibility I explored was to publish the images using ros and save it into a rosbag file and extract the images later using image_view. However after this process, quite a few images were missing ( I tried to save the images simultaneously using cv2,imwrite for just processed images).
Please let me know if you have leads as to how to solve this problem.
-P
cv2.imwrite(raw_img_name,cv_image_orig);
np.savetxt(depth_data_raw, depth_image_raw)
cv2.imwrite(crop_img_name, crop_img);
# Publishing the cropped image to the Jetson
msg = Image()
msg.encoding = 'bgr8'
msg.height = crop_img.shape[0]
msg.width = crop_img.shape[1]
msg.step = crop_img.shape[1] * 3
msg.data = crop_img.tostring()
self.pub_seg.publish(msg)
