You can use the below function to resize the product base image and get resized image URL.

public function __construct(
    ..
    \Magento\Catalog\Block\Product\Context $productContext,
    ...
) {    
    ...
    $this->productImageHelper = $productContext->getImageHelper();
    ...
}

function getImageUrl($productObject)
{
     $width = 180;
     $height = 180;

     $resizedImage = $this->productImageHelper
        ->init($productObject, 'product_base_image')
        ->constrainOnly(TRUE)
        ->keepAspectRatio(TRUE)
        ->keepTransparency(TRUE)
        ->keepFrame(TRUE)
        ->resize($width, $height)
        ->getUrl();

      return $resizedImage;
}
