opencv - What are Python constants for cv2.solvePnP method flag? -

-

i need use cv_p3p solvepnp method, there doesn't seem documentation of python equivalents of c++ flags, cv_iterative, cv_p3p , cv_epnp. i've tried cv2.cv_p3p, cv2.p3p, cv2.cv.p3p, etc.

i've found few questions asking this, including these:

http://opencv-users.1802565.n2.nabble.com/solvepnp-name-of-flag-constants-in-python-td7484093.html

http://answers.opencv.org/question/8861/what-opencv-constants-are-available/

but no answers, apart link source page, defines python constants. there seem no references constants i'm looking for. https://github.com/itseez/opencv/blob/e3ae36dcb3c1d523802f8642e5c3984db43637c4/modules/python/src2/defs

i tried passing integers argument, still seems using default method.

is possible other solve methods don't exist in python version of opencv?

i found following constants worked:

cv2.solvepnp_iterative

cv2.solvepnp_p3p

cv2.solvepnp_epnp

cv2.solvepnp_dls

e.g:

retval, orvec, otvec = cv2.solvepnp(object_points, image_points,              camera_matrix, none, none, none, false, cv2.solvepnp_iterative)

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i...

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
