您可以将图像ng-repeat分组在一起，也可以将其分组。除了一些所需的样式修复之外，以下是方法：

HTML：

<carousel interval="myInterval">
  <slide ng-repeat="slideCollection in groupedSlides" active="slide.active">
    <div>
      <img ng-src="{{slideCollection.image1.image}}" style="margin:auto;">      
      <img ng-src="{{slideCollection.image2.image}}" style="margin:auto;">      
    </div>
  </slide>
</carousel>

JavaScript：

$scope.$watch('slides', function(values) {
  var i, a = [], b;

  for (i = 0; i < $scope.slides.length; i += 2) {
    b = { image1: $scope.slides[i] };

    if ($scope.slides[i + 1]) {
      b.image2 = $scope.slides[i + 1];
    }

    a.push(b);
  }

  $scope.groupedSlides = a;
}, true);
