Types of camera interfaces

It can be divided into 2 class , They are standard interface and onboard interface . Standard interfaces include ：usb, so . Onboard interfaces include ：mipi-csi Interface . This blog will discuss the advantages and disadvantages of various docking methods in the process of practical application .

Standard interface

usb Interface

advantage 、 Inferiority

Use usb The camera of the interface , Lowest cost ,python The access to is also the simplest , It appears in almost all beginners demo Stage . The problem is usb The way of docking , Once the heat expands and contracts , The interface will not contact well , In case of shock , The video signal will be broken , The deployment environment is required to be stable , It cannot be used in harsh environment . Of course, for this form of hardware docking , You can put usb Remove the interface , Then connect the wire directly with the welding gun , But I haven't tried this way , It can be used as a scheme .

python Code case

""" OpenCV Read camera video stream , And display   similar demo1.py Display picture in  """
