  background-size: cover;
  transition: transform 5000ms linear 0s;

<div class="sliderimg" style="background-image: url('http://images.unsplash.com/photo-1419064642531-e575728395f2?crop=entropy&fit=crop&fm=jpg&h=800&ixjsv=2.1.0&ixlib=rb-0.3.5&q=80&w=2400')">
  <div class="carousel-caption">

我不确定转换是否发生在文档加载时。我会改用动画:

@keyframes example {
  from {transform: scale(1, 1)}
  to {transform: scale(1.05, 1.05)}
}

div.sliderimg {
  animation-name:example;
  animation-duration:5s;
  animation-fill-mode: forwards;
}
