How would you determine the distance between the camera and object?

How would you determine the distance between the camera and object?

The camera is equipped with a one non-stereoscopic lens. The measured distance is determined on the basis of one view of an object presented on one image. The image is made at a constant and invariant setting of the optical path such as: focus, aperture and focal length.

How do I know if OpenCV supports CUDA?

If OpenCV is compiled with CUDA capability, it will return non-zero for getCudaEnabledDeviceCount function (make sure you have CUDA installed). Another very simple way is to try using a GPU function in OpenCV and use try-catch. If an exception is thrown, you haven’t compiled it with CUDA.

What is cv2 DNN?

cv2. dnn. : [blobFromImage] creates 4-dimensional blob from image. Optionally resizes and crops image from center, subtract mean values, scales values by scalefactor , swap Blue and Red channels.

What is a caffe model?

CAFFE (Convolutional Architecture for Fast Feature Embedding) is a deep learning framework, originally developed at University of California, Berkeley. It is open source, under a BSD license. It is written in C++, with a Python interface.

Is Caffe faster than TensorFlow?

Caffe has more performance than TensorFlow by 1.2 to 5 times as per internal benchmarking in Facebook. TensorFlow works well on images and sequences and voted as most-used deep learning library whereas Caffe works well on images but doesn’t work well on sequences and recurrent neural networks.

How do you make a caffe model?

To get a caffemodel you need to train the network. That prototxt file is only to deploy the model and cannot be used to train it. You need to add a data layer that points to your database. To use a list of files as you mention, the source of the layer should be HDF5.
