problem with kinect_v1 #45

Closed CyrillUNICA closed 2 years ago

CyrillUNICA commented 3 years ago

Hi, I'm very interested in your project connecting GemPy with an AR Sandbox. I'm running open_AR_Sandbox on Linux Mint with an kinect_v1 sensor. Via jupyter notebook I calibrated the projector and sensor. I got some problems with the kinect_v1 sensor and I would like to ask if you have some fixing advices: 1) Sensor image is flashlightning 2) Sensor image is mirror inverted (central inversion) 3) Kernel on jupyter notebook is crashing periodically despite having just one active Kernel Thanks for help!

Hi @CyrillUNICA,

Please excuse the late reply - do the problems still persist?

CyrillUNICA commented 3 years ago

Hi @flohorovicic , thank you for replying, I resolved the flashlightning and the Kernel crashing, but I have still issues with the sensor image, i'ts mirror inverted (central inversion). Probably it's quiet easy to flip the image but i don't know where I have to change the kinect parameters to do so. Some advice??

Hi @CyrillUNICA, Try commenting out line 40 and line 49 in sandbox/sensor/kinect_v1.py

unfortunately I do not have a kinect 1 for testing but if you can confirm that this works I will fix this and pull it into main.

Best regards Simon

Hi @SimonVirgo, thank you in the meantime I could find a kinect v2 which appears to be more stable. Nevertheless I got still the same issue, the sensor-image is flipped. Ho may I flip the image? Thanks for your help!! Cyrill

hello @CyrillUNICA, The flipped sensor image is indeed strange. Can you confirm that it is a mirrored image and not rotated by 180 degree? I guess the best way to fix this is for us to extent the calibration with flags for flipping and /or rotation. I cannot promise that we will manage to do do this within the next days, but I will put it on the list.

CyrillUNICA commented 2 years ago

It's actually rotated by 180 degrees. I thought that means flipped... Here an example of what I see: flip-rotate

SimonVirgo commented 2 years ago

ah, I see! Any chance you can mount the kinect the other way around in you setup? more precisely with the bottom of the kinect facing the backside of the sandbox? I must admit we did not think of this case. It makes a lot of sense to have different types of hardware setup reflected in the code, so we will implement a flag for this soon. However depending on if we want to do this in the sensor class or in the calibration this might take a while.

You were right, it was as simpole as that. Thanks a lot!
