problems in "get_box3d_corners" in "model_utils.py"
line 109 in "Model_utils.py" : mean_sizes = tf.expand_dims(tf.constant(g_mean_size_arr, dtype=tf.float32), 0) + size_residuals #(B,NS,1)
-
the shape of mean_sizes shouldn't be #(B,NS,3)?
-
I do not understand why "mean_sizes" would be "g_mean_size_arr + size_residuals "? “g_mean_size_arr” isn't the ""mean_sizes" itself?
and in Line 110 why the sizes would be "mean_sizes + size_residuals"? Isn't it adds "size_residuals" for two times?
In Line 373:
mean_sizes = tf.expand_dims(
tf.constant(g_mean_size_arr, dtype=tf.float32), 0) # (1,NS,3)
what's the difference between the two "mean_sizes"?
Hoping to get some reply!Thanks sincerely !
I am also confused about the two "size_residuals" . @charlesq34
@charlesq34 i have the same confusion
