Requesting Update to OpenCV 4.5.3

Windwoes commented 3 years ago

Any specific thing you're looking to gain from a newer version? Not all improvements apply to the Android build.

We are going for obstacle detection using intel realsense cameras. depth frames can be processed to remove ground point so that obstacles like other robots can be detected and avoided. Something similar to this: http://www.sayef.tech/post/ground-detection-and-removal-from-point-clouds/ OpenCV 4.5 has an update to RANSAC that might perform well enough on control hub hardware: https://opencv.org/evaluating-opencvs-new-ransacs/

Hmm, I am looking into this, but when I locally test 4.5.3, I am getting a dynamic linker error at runtime:

dlopen failed: library "libc++_shared.so" not found

Windwoes commented 3 years ago

Okay, managed to get past that by using a dummy target to have gradle pull that in.

If you add this maven staging repo:

repositories {
    maven { url 'https://oss.sonatype.org/content/repositories/orgopenftc-1008/'}
}

You should be able to give my test build for 4.5.3 a try by doing the following:

dependencies {
    implementation ('org.openftc:easyopencv:1.4.4') {
        exclude group: "org.openftc", module: "opencv-repackaged"
    }
    implementation 'org.openftc:opencv-repackaged:5.4.3-B'
}

Edit: whoops, I typoed the version number when I uploaded to the staging repo, (5.4.3 instead of 4.5.3). Doesn't really affect anything, I'll fix that before releasing.

Here's the updated native library.

libOpenCvAndroid543.zip

Sweet - It Works!!!

Do you want me to close it now or once you release it?

Windwoes commented 3 years ago

Once I release it. Does the new version provide the improvements you were hoping for?

IronReignRobotics commented 3 years ago

It does. Not that we've been able to implement yet, but it has the ransac/usac improvements introduced in 4.5.0. Thank you!
