On the Internet there are lots of publications concerning Baidu wrong coordinates. That misunderstanding happens because a lot of different exsisting positioning systems may have different coordinates. Here is the script, which transforms Google coordinates to Baidu coordinates.

<script type="text/javascript">
var map = new BMap.Map("container");
map.addControl(new BMap.NavigationControl());
map.addControl(new BMap.MapTypeControl({mapTypes : [BMAP_NORMAL_MAP, BMAP_SATELLITE_MAP]}));
map.enableScrollWheelZoom();
var tmp = convertWGS84toBD09(22.234327, 113.58507);
var point = new BMap.Point(tmp.lon, tmp.lat);
var marker = new BMap.Marker(point, {});
map.addOverlay(marker);
map.centerAndZoom(point, 16);

If you want to match a certain point on Google satelite view to a map view, use convertWGS84toGCJ02 function.
Different versions of Baidu maps API have small differences in algorithms. Those script is for v1.3.
