# Multi-target Tracking Result
|
|
|
|
The MOTResult code is defined in `fastdeploy/vision/common/result.h`, and is used to indicate the detected target frame, target tracking id, target class and target confidence ratio in multi-target tracking task.
|
|
|
|
## C++ Definition
|
|
|
|
```c++
|
|
fastdeploy::vision::MOTResult
|
|
```
|
|
|
|
```c++
|
|
struct MOTResult{
|
|
// left top right bottom
|
|
std::vector<std::array<int, 4>> boxes;
|
|
std::vector<int> ids;
|
|
std::vector<float> scores;
|
|
std::vector<int> class_ids;
|
|
void Clear();
|
|
std::string Str();
|
|
};
|
|
```
|
|
|
|
- **boxes**: Member variable which indicates the coordinates of all detected target boxes in a single frame. `boxes.size()` indicates the number of boxes, each box is represented by 4 float values in order of xmin, ymin, xmax, ymax, i.e. the coordinates of the top left and bottom right corner.
|
|
- **ids**: Member variable which indicates the ids of all targets in a single frame, where the element number is the same as `boxes.size()`.
|
|
- **scores**: Member variable which indicates the confidence level of all targets detected in a single frame, where the number of elements is the same as `boxes.size()`.
|
|
- **class_ids**: Member variable which indicates all target classes detected in a single frame, where the element number is the same as `boxes.size()`.
|
|
- **Clear()**: Member function used to clear the results stored in the structure.
|
|
- **Str()**: Member function used to output the information in the structure as string (for Debug).
|
|
|
|
## Python Definition
|
|
|
|
```python
|
|
fastdeploy.vision.MOTResult
|
|
```
|
|
|
|
- **boxes**(list of list(float)): Member variable which indicates the coordinates of all detected target boxes in a single frame. It is a list, and each element in it is also a list of length 4, representing a box with 4 float values representing xmin, ymin, xmax, ymax, i.e. the coordinates of the top left and bottom right corner.
|
|
- **ids**(list of list(float)): Member variable which indicates the ids of all targets in a single frame, where the element number is the same as `boxes`.
|
|
- **scores**(list of float): Member variable which indicates the confidence level of all targets detected in a single frame.
|
|
- **class_ids**(list of float): Member variable which indicates all target classes detected in a single frame.
