具体地，上述两组LED发光单元110中，其中一组LED发光单元与所述体感摄像头200之间的距离相对较近，另一组LED发光单元110与所述体感摄像头200之间的距离相对较远。当需要对体感摄像头200进行精度测量时，控制单元120可以首先点亮与所述体感摄像头200之间具有较近距离的LED发光单元110，以利用该组LED发光单元110对所述体感摄像头200进行精度测试。当测试完成以后，控制单元120可以再点亮另一组LED发光单元110，以利用该组LED发光单元110对所述体感摄像头200进行精度测试。
当然，本实施例中所设置的LED发光单元110并不限于两组，其还可以包括多组LED发光单元110，该多组LED发光单元110可以与所述体感摄像头200之间具有不同的预设距离。
优选地，如图2和图3所示，所述装置还包括与所述LED发光单元110一一对应的灯柱150，每组所述LED发光单元110设置在与其所对应的所述灯柱150内。
这样，每组LED发光单元110中的所有的LED发光器件111可以间隔设置在灯柱150内，从而可以使得各LED发光器件111相对地面具有不同的预设高度。从而，可以利用LED发光单元110对体感摄像头200进行高度精度测试。
优选地，如图2和图3所示，所述装置还包括测试暗室160，所述灯柱150设置在所述测试暗室160内。
本实施例的体感摄像头的精度测量装置100，其包括一个测试暗室160，也就是说，该测试暗室160为一个不透光的测试暗室。这样，其可以解决自然光或者生产环境中的白炽灯等环境光的干扰，从而可以提高体感摄像头的测试精度。
优选地，所述控制单元120包括单片机。
优选地，所述单片机还用于与终端通信连接，以接收终端发送的测试请求；
