depth information from Astra camera
Hello,
I am trying to get the distance to the defined object by using Astra camera with /camera/depth/image_raw topic. By using OpenCV library and RGB image from topic /camera/rgb/image_raw I have defined the object and get the center position of the object. Now I want to get the distance to that center, I read that the depth_image with 32FC1
encoding from depth topic gives you the distance of each pixel in meters. But when I am trying to do that in that way:
depth = depth_image[self.position[0], self.position[1]]
I got strange value like 1169 or the values which are very close to it regardless of the distance.
Could someone help me regards,
