- Colorimage and depthimage:
1.一个可以运行YOLOv5的python环境
pip install -r requirements.txt
2.一个realsense相机和pyrealsense2库
pip install pyrealsense2
在下面两个环境中测试成功
win10 python 3.8 Pytorch 1.10.2+gpu CUDA 11.3 NVIDIA GeForce MX150
ubuntu16.04 python 3.6 Pytorch 1.7.1+cpu
修改模型配置文件,以yolov5s为例。
如果使用自己训练的模型,需要进行相应的修改。

分辨率好像只能改特定的参数,不然会报错。d435i可以用 1280x720, 640x480, 848x480。
pipeline = rs.pipeline() # 定义流程pipeline
config = rs.config() # 定义配置config
config.enable_stream(rs.stream.depth, 1280, 720, rs.format.z16, 30)
config.enable_stream(rs.stream.color, 1280, 720, rs.format.bgr8, 30)
profile = pipeline.start(config) # 流程开始
下方代码实现从像素坐标系到相机坐标系转换,并且标注中心点以及三维坐标信息。
for i in range(len(xyxy_list)):
ux = int((xyxy_list[i][0]+xyxy_list[i][2])/2) # 计算像素坐标系的x
uy = int((xyxy_list[i][1]+xyxy_list[i][3])/2) # 计算像素坐标系的y
dis = aligned_depth_frame.get_distance(ux, uy)
camera_xyz = rs.rs2_deproject_pixel_to_point(
depth_intrin, (ux, uy), dis) # 计算相机坐标系xyz
camera_xyz = np.round(np.array(camera_xyz), 3) # 转成3位小数
camera_xyz = camera_xyz.tolist()
cv2.circle(canvas, (ux,uy), 4, (255, 255, 255), 5)#标出中心点
cv2.putText(canvas, str(camera_xyz), (ux+20, uy+10), 0, 1,
[225, 255, 255], thickness=2, lineType=cv2.LINE_AA)#标出坐标
camera_xyz_list.append(camera_xyz)
#print(camera_xyz_list)
