新建评估所需的内容如下：

1.基准数据集：用于评估指标计算的基准参考数据，如在一般模型评估场景中的：**真值数据**

基准数据目前仅支持选择TensorBay中的数据集，如需要使用本地或其他云存储上的数据，请先将数据上传至TensorBay，详情请查看

{% content-ref url="/pages/-MWSbbiz429ASW3po9Q\_" %}
[数据集准备](/guide/tensorbay/data.md)
{% endcontent-ref %}

2.评估标注类型：需要评估的数据标注类型，目前支持Box2D、POLYGON和POLYLINE2D

3.评估标注标签：需要评估的标注标签内容

4.IoU阈值：人为设定的IoU的阈值，在评估中高于该阈值的矩形框被认为是命中目标，反之则被认为未命中，需要填写一个0-1之间的两位小数

{% hint style="info" %}
目前单个评估仅支持添加一个IoU阈值进行评估，多阈值同时评估相关功能敬请期待
{% endhint %}
