We are a university group working on a capstone project using the OpenMV Cam H7 and Wifi Shield.
We have been experiencing problems that don’t not seem to be originating with our code.
In our script we are creating TCP sockets as server to receive files from a client, and then we are using the example code snippets of snapshot on face detection and face recognition.
We have been using the OpenMV cam for about two months. Since early October, there has been issues with the computer and OpenMV IDE recognizing the camera when it is plugged in. When we plug in the camera, our Windows 10 computer tells us “There is problem with this drive. scan now and fix it.” We have not scanned/fixed it in case that would mess anything up with the camera. However, this warning message has only showed up when we have the uSD card inserted. Is there a problem?
We were having problems in our facial detection/recognition code - we have a loop that includes the example code snippets of snapshot on face detection and face recognition - there are several iterations of the loop that occurs for about 3 minutes. However, we were having problems that the camera was randomly resetting in trying to save the snapshot to the SD card. We have just updated the firmware on the camera, as well as took out the SD card and reinserted it, which has seemed to solve this problem for now.
However, in running our code again, it seems that the snapshot_on_facial_detection code is not working Nearly as well as it used to. The camera is really struggling to detect a face, even though before, under the same conditions, it could easily and quickly detect a face. Did something change in the firmware update to have caused this?
