Python implementation of Poisson Multi-Bernoulli Mixture Filter for Multi-Object Tracking.
Hi, @erikbohnsack . thanks for supply this code. However, I confused this algorithm is pmbm ? because I found the code about possion birth is not valid. I think this code is mbm algorithm, is it rightly?
Hi, thanks for sharing this great code. Im unsure whether its a mistake or i dont understand something. Does this correspond to the update of the undetected objects modeled by Poisson point process that are missdetected again? Shouldn't it have a factor 1 - self.detection_probability
then? My reference is the handout 5 from the edX course "Multi-Object Tracking for Automotive Systems" that describes the PMBM update.

i have tried the command pip3 install ./murty and it is not work. how can i solve the problem?
thx
When doing the command git submodule update, I cannot obtain the ./Murty file.
Hello, thanks for your wonderful work and it's so kind of you to open source.
When I try to run your code by putting all codes in runforrest.ipynb
file together, I found it may miss some files, such as the mot/fafe/showroom/showroom_all/showroom_bev_NN/logs/log-seq
specified by log_root
variable and the mot/fafe/showroom/weights_2019-05-03_14-01_epoch_110_fafe
file specified by showroom_fafe
variable.
Could you offer some help and point out some clues to run your code to get the results like yours.
Thanks a lot.
Hi,
When I read your code in detail, I'm confused about the calculation process in utils/coord_transfer.py
:
def coordinate_transform_CV(state, imu_data, dt, object_class=None):
assert state.shape == (4, 1)
# Minus as the imu_data is for the ego vehicle
angle = - imu_data.ru * dt
# minus angle holds here as well
rotation_matrix = np.array([[math.cos(angle), - math.sin(angle)],
[math.sin(angle), math.cos(angle)]])
translation = np.array([[- imu_data.vl * dt],
[imu_data.vf * dt]])
output_state = np.copy(state)
output_state[0:2] = rotation_matrix @ state[0:2] - translation
output_state[2:4] = rotation_matrix @ state[2:4]
# same argument for minus translation here as above.
return output_state
I understand that you use the IMU information to transform the objects state from last frame to current frame in ego vehicle, so we can get the absolute tracking velocity. So the equation
output_state[0:2] = rotation_matrix @ state[0:2] - translation
should be
output_state[0:2] = rotation_matrix @ (state[0:2] - translation)
when do the inverse transformation, right?
However when I correct it, the results seems the same. I'm not sure whether I'm wrong.
