PHP图像识别测试

PHP图像识别测试，纯粹为了好玩，无法应用到实际中，对原图要求很严格！必须是固定大小，固定间距的才好识别~ 原理比较简单，把一个图片，我这里是330px*60px，像素化，取每一个像素上的色值，根据一定规律，分为0和1 因为数字是横着排列的，我们要切割开，与样本数据做对比，原代码采用了把图片顺时针旋转90度，然后读出数据做对比~ 因为手机号有11位数字，图片大小330 X 60，即每个数字占 30 X 60的区域，    横着读（将色值转换为0和1），竖着读（方便与样本做对比），判断超过80%或90%相似度，算识别成功，得到结果！ 数字做特殊处理，例如加粗，斜体，放大，缩小都会影响识别结果，因为已有样本数据没那么多，所以对原图要求很严格~ 如果用来识别车牌号，应该能完美胜任，车牌号都是固定的尺寸，字母间距~ 实验效果如下：   添加点干扰线，效果就比较差了，不能完整识别~ 如果你有兴趣，可以用PS多做几个img.png图片，测试~ 原文地址：https://www.php.cn/php-weizijiaocheng-399377.html?_blank 代码做些了小调整~ ```php <?php /** * 电话号码识别. * @author by zsc for 2010.03.24 */ class gjPhone { protected $imgPath; // 图片路径 protected $imgSize; // 图片大小 protected $hecData; // 分离后数组 protected $horData; // 横向整理的数据 protected $verData; // 纵向整理的数据 function __construct ($path) { $this->imgPath = $path; } /** * 颜色分离转换... * * 按像素，分隔为，0和1 * @param unknown_type $path * @return unknown */ public function getHec () { $size = getimagesize($this->imgPath); $res = imagecreatefrompng($this->imgPath); for ($i = 0; $i < $size[1]; ++ $i) { for ($j = 0; $j < $size[0]; ++ $j) { $rgb = imagecolorat($res, $j, $i); $rgbarray = imagecolorsforindex($res, $rgb); if ($rgbarray['red'] < 125 || $rgbarray['green'] < 125 || $rgbarray['blue'] < 125) { $data[$i][$j] = 1; } else { $data[$i][$j] = 0; } } } $this->imgSize = $size; $this->hecData = $data; } /** * 颜色分离后的数据横向整理... * * @return unknown */ public function magHorData () { $data = $this->hecData; $size = $this->imgSize; $z = 0; for ($i = 0; $i < $size[1]; ++$i) { if (in_array('1', $data[$i])) { $z ++; for ($j = 0; $j < $size[0]; ++$j) { if ($data[$i][$j] == '1') { $newdata[$z][$j] = 1; } else { $newdata[$z][$j] = 0; } } } } return $this->horData = $newdata; } /** * 整理纵向数据... * * @return unknown */ public function magVerData ($newdata) { for ($i = 0; $i < 330; ++$i) { for ($j = 60; $j > 0; $j--) { $ndata[$i][$j] = @$newdata[$j][$i]; } } $sum = count($ndata); $c = 0; $ndatas = array(); for ($a = 0; $a < $sum; $a ++) { $value = $ndata[$a]; if (in_array(1, $value)) { $ndatas[$c] = $value; $c ++; } elseif (is_array($ndatas)) { $b = $c - 1; if (in_array(1, isset($ndatas[$b]) ? $ndatas[$b] : array() )) { $ndatas[$c] = $value; $c ++; } } } return $this->verData = $ndatas; } /** * 显示电话号码... * * @return unknown */ public function showPhone ($ndatas) { $phone = null; $d = 0; $ndArr = array(); foreach ($ndatas as $key => $val) { if (in_array(1, $val)) { foreach ($val as $k => $v) { @$ndArr[$d] .= $v; } } if (!in_array(1, $val)) { $d ++; } } foreach ($ndArr as $key01 => $val01) { $phone .= $this->initData($val01); } return $phone; } /** * 分离显示... * * @param unknown_type $dataArr */ function drawWH ($dataArr) { echo '<div style="font-size:8px;">'; $c = ''; if (is_array($dataArr)) { foreach ($dataArr as $key => $val) { foreach ($val as $k => $v) { if ($v == 0) { $c .= "<font color='#FFFFFF'>" . $v .
