Hello guys, I am trying to convert a bunch of images into a video, I got OpenCV code working perfectly fine on the Windows machine but videos I make on windows machine doesn't seem to work on pi using opencv. So I thought I'll just run the same code on pi and encode the images on the pi itself. The ...

I've upgraded my pi image to Jessie and having issues with connection via SSH to the root user. Upon trying to connect it says Access denied.

It happily connects to Pi user but not root. I've renamed root password and everything but still doesn't work.

Any ideas what's the problem?

Thanks

Thanks for the replies guys :) Paeryn the change of starting point didn't work so I wrote a for loop and changed the starting pointer on the array. This is the draw call now and it works: void Renderer::draw(pcl::PointCloud<pcl::PointXYZRGB>::Ptr pointCloud) { // Set the viewport glViewport(0, 0, th...

Yeah it seems to be the case, is it possible to make up a point cloud out of multiple 65535 point segments? e.g: glVertexAttribPointer(posAttrib, 4, GL_FLOAT, GL_FALSE, 8 * sizeof(GLfloat), (GLvoid *)segment1); glEnableVertexAttribArray(posAttrib); glDrawArrays(GL_POINTS, 0, 65535); glVertexAttribPo...

Hi guys,

Seems to have an issue with OpenGLES2.0 as it can only draw up to 65535 on my: call.
So is there any way to increase the point count for the call?

Thanks.

Hello guys, I am trying to compile Point cloud library on my Pi2 but having lots of issues with swap and so on. So I saw an advice to compile on another Linux machine using armv7 cflag and then move the files to pi2 and do make install. I was wondering how would I got about to do this? I got a machi...

Thanks drhastings, it worked nicely.

Looking more at it, it seems that It's not really possible to use quite a few features of this chip on linux.

I am trying to find some better open source alternatives.

I'd ask Víctor Mayoral who wrote the code on GitHub. Invensense have not published specs to access their motion detection though it has been reverse engineered several times, though I think for the quaternion data mainly. I think you stand a better chance talking to the author of the code for such ...

Hi guys, I am trying to figure out how to get the rotation matrix out of the MPU-9150 Nine-Axis IMU sensor, I am using the linux-mpu9150 code with imu.c which gives me the: euler_angles, fused_quaternion, calibrated_accel and calibrated_mag But on the spec it says: Digital-output 9-axis MotionFusion...

Hi guys,

Is it possible to get a newer version of code::blocks other than 10.05 on the raspberry pi for Raspbian??

sudo apt-get install codeblocks only installs 10.05 which is really old and quite slow.

Thanks

Fixed it

needed to add to my .cpp file

and to the g++ command

Hi, I am working on getting some OpenCv code working on the Pi. I got OpenCV installed using sudo apt-get install libopencv-dev and using RaspiCam: C++ API for using Raspberry camera the code I am using is quite simple : #include <ctime> #include <iostream> #include <raspicam/raspicam_cv.h> using na...

Thank you topguy it worked brilliantly

You are only missing to tell the linker that the missing libraries is located in "/opt/vc/lib/". In the guide you linked to he uses full path to those libs but I guess you should only need to add: -L/opt/vc/lib Why thank you that worked right away :) now just running the application fails. ./simple...

Hey guys, I am working on a project of porting my OpenCV code from Windows to raspberry pi but I am having hard time finding a way to get OpenCV C++ working. I've found many guides but they seemed to only have libraries and code support for only C. The only promising one I found was this: RaspiCam: ...
