# Target Detection Result
|
|
|
|
The DetectionResult code is defined in `fastdeploy/vision/common/result.h`, and is used to indicate the target frame, target class and target confidence level detected in the image.
|
|
|
|
## C++ Definition
|
|
|
|
```c++
|
|
fastdeploy::vision::DetectionResult
|
|
```
|
|
|
|
```c++
|
|
struct DetectionResult {
|
|
std::vector<std::array<float, 4>> boxes;
|
|
std::vector<float> scores;
|
|
std::vector<int32_t> label_ids;
|
|
std::vector<Mask> masks;
|
|
bool contain_masks = false;
|
|
void Clear();
|
|
std::string Str();
|
|
};
|
|
```
|
|
|
|
- **boxes**: Member variable which indicates the coordinates of all detected target boxes in a single image. `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.
|
|
- **scores**: Member variable which indicates the confidence level of all targets detected in a single image, where the number of elements is the same as `boxes.size()`.
|
|
- **label_ids**: Member variable which indicates all target categories detected in a single image, where the number of elements is the same as `boxes.size()`.
|
|
- **masks**: Member variable which indicates all detected instance masks of a single image, where the number of elements and the shape size are the same as `boxes`.
|
|
- **contain_masks**: Member variable which indicates whether the detected result contains instance masks, which is generally true for the instance segmentation model.
|
|
- **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).
|
|
|
|
```c++
|
|
fastdeploy::vision::Mask
|
|
```
|
|
```c++
|
|
struct Mask {
|
|
std::vector<int32_t> data;
|
|
std::vector<int64_t> shape; // (H,W) ...
|
|
|
|
void Clear();
|
|
std::string Str();
|
|
};
|
|
```
|
|
- **data**: Member variable which indicates a detected mask.
|
|
- **shape**: Member variable which indicates the shape of the mask, e.g. (h,w).
|
|
- **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.DetectionResult
|
|
```
|
|
|
|
- **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.
|
|
- **scores**(list of float): Member variable which indicates the confidence level of all targets detected in a single image.
|
|
- **label_ids**(list of int): Member variable which indicates all target categories detected in a single image.
|
|
- **masks**: Member variable which indicates all detected instance masks of a single image, where the number of elements and the shape size are the same as `boxes`.
|
|
- **contain_masks**: Member variable which indicates whether the detected result contains instance masks, which is generally true for the instance segmentation model.
|
|
|
|
```python
|
|
fastdeploy.vision.Mask
|
|
```
|
|
- **data**: Member variable which indicates a detected mask.
|
|
- **shape**: Member variable which indicates the shape of the mask, e.g. (h,w).
