Issue
I'm trying to integrate ARCore with ML Kit in Android Studio as suggested in ARCore documentation official. This is my JAVA code:
ObjectDetector objectDetector = createObjectDetector();
Image cameraImage = null;
try {
cameraImage = frame.acquireCameraImage();
// Process `cameraImage` using your ML inference model.
objectDetector.process(InputImage.fromMediaImage(cameraImage, getRotationCompensation("1", this, false)))
.addOnSuccessListener(
new OnSuccessListener<List<DetectedObject>>() {
@Override
public void onSuccess(List<DetectedObject> detectedObjects) {
// Task completed successfully
// The list of detected objects contains one item if multiple
// object detection wasn't enabled.
for (DetectedObject detectedObject : detectedObjects) {
Rect boundingBox = detectedObject.getBoundingBox();
Integer trackingId = detectedObject.getTrackingId();
for (DetectedObject.Label label : detectedObject.getLabels()) {
String text = label.getText();
if (PredefinedCategory.FOOD.equals(text)) {
}
int index = label.getIndex();
if (PredefinedCategory.FOOD_INDEX == index) {
}
float confidence = label.getConfidence();
}
}
}
})
.addOnFailureListener(
new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
// Task failed with an exception
Log.e("Failure Listener", e.getMessage());
}
});
} catch (NotYetAvailableException e) {
// NotYetAvailableException is an exception that can be expected when the camera is not ready
// yet. The image may become available on a next frame.
} catch (RuntimeException e) {
// A different exception occurred, e.g. DeadlineExceededException, ResourceExhaustedException.
// Handle this error appropriately.
Log.e("Error", e.toString());
} catch (CameraAccessException e) {
e.printStackTrace();
} finally {
if (cameraImage != null) {
cameraImage.close();
}
}
I'm getting the following errors:
Internal error has occurred when executing ML Kit tasks Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x4faee70000000 in tid 14906 ...
The error appears because of objectDetector.process(...)
but I'm not sure what I did wrong
Solution
It worked when I commented the initial closing of the image and closed the image in the OnCompleteListener instead. This is my modified code:
ObjectDetector objectDetector = createObjectDetector();
Image cameraImage = null;
try {
cameraImage = frame.acquireCameraImage();
// Process `cameraImage` using your ML inference model.
Image finalCameraImage = cameraImage;
objectDetector.process(InputImage.fromMediaImage(finalCameraImage, getRotationCompensation("1", this, false)))
.addOnSuccessListener(
new OnSuccessListener<List<DetectedObject>>() {
@Override
public void onSuccess(List<DetectedObject> detectedObjects) {
// Task completed successfully
// The list of detected objects contains one item if multiple
// object detection wasn't enabled.
for (DetectedObject detectedObject : detectedObjects) {
Rect boundingBox = detectedObject.getBoundingBox();
Log.d("Bounding Box", boundingBox.toString());
Integer trackingId = detectedObject.getTrackingId();
for (DetectedObject.Label label : detectedObject.getLabels()) {
String text = label.getText();
if (PredefinedCategory.FOOD.equals(text)) {
}
int index = label.getIndex();
if (PredefinedCategory.FOOD_INDEX == index) {
}
float confidence = label.getConfidence();
}
}
}
})
.addOnFailureListener(
new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
// Task failed with an exception
Log.e("Failure Listener", e.getMessage());
}
}).addOnCompleteListener(new OnCompleteListener<List<DetectedObject>>() {
@Override
public void onComplete(@NonNull Task<List<DetectedObject>> task) {
finalCameraImage.close();
}
});
} catch (NotYetAvailableException e) {
// NotYetAvailableException is an exception that can be expected when the camera is not ready
// yet. The image may become available on a next frame.
} catch (RuntimeException e) {
// A different exception occurred, e.g. DeadlineExceededException, ResourceExhaustedException.
// Handle this error appropriately.
Log.e("Error", e.toString());
} catch (CameraAccessException e) {
e.printStackTrace();
} finally {
// if (cameraImage != null) {
// cameraImage.close();
// }
