Get the Depth Data

[fshamsafar]

Thank you for this python library for Kinect Azure.

I could run the example.py successfully. But how can I get access to the depth data? I want the depth information to further be processed by some other algorithms.

I added depth = k4a.capture_get_depth_image(capture) and k4a.image_release(depth). But it did not obtain the depth.

Thanks

I think you're missing a k4a.image_get_buffer() call. We're using something like: capture = k4a.Capture() res = k4a.device_get_capture(dev, capture, 1000) if res == k4a.K4A_WAIT_RESULT_SUCCEEDED: img = k4a.capture_get_depth_image(capture) if img: imx = np.array(k4a.image_get_buffer(img)) ... del capture To access the depth image and manage the capture. Hope this helps!

Thanks :) It worked :) The output for K4A_COLOR_RESOLUTION_720P is an array of dimension 245520. But why it does not match with the image_get_height_pixels(img), which is 720 and image_get_width_pixels(img), which is 1280. I mean totally it should have 720*1280*3=2764800 values and not 245520. What is missing here for reshaping the flattened data to an image?

I don’t think depth and color image are the same camera — and I don’t think depth is square — check the documentation here: https://docs.microsoft.com/en-us/azure/Kinect-dk/hardware-specification

If it is depth value, how to transform the values to mm? The values looks look grey values from 0 to 255.
And the depth returns a vector, how to transform it to array(image)?
