Please try the below code in your product detail page template.

For Current product category ids

<?php 
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->get('Magento\Framework\Registry')->registry('current_product');
$categories = $product->getCategoryIds(); /*will return category ids array*/

?>

Load the product by category id

     $categoryId=" Take the id from your current product categories array"
        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
        $category= $objectManager->get('Magento\Catalog\Model\CategoryFactory')->create()->load($categoryId);
        $collection = $objectManager->get('Magento\Catalog\Model\ResourceModel\Product\CollectionFactory')->create()
        $collection->addAttributeToSelect('*');
        $collection->addCategoryFilter($category);
        $collection->addAttributeToFilter('visibility', \Magento\Catalog\Model\Product\Visibility::VISIBILITY_BOTH);
       collection->addAttributeToFilter('status',\Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED);
return $collection;

Hope it will help you!
