Only camera pose track ,But no map established

[xjtao1314]

Hello there,
Thank you for your great work. I test the whole camera XP2 and program .
The platform is
cpu i7 7700
system :Ubuntu 14.04 with kernel 4.4.0-31
Question : there is only camera trajectory show as below, and failed to save map ,instead give many log files in the given path? Is that a normal display?

Hi @xjtao1314
Can you post the command you use?
The program only displays map when you use -pb_load with the saved map.
To save map, you need to add a -pb_save xxxx option, where xxxx indicates the location of the map to be saved(eg. /tmp/room.pb). When you are done recording the map, make sure to press ESC for the program to exit normally and save the map.
Let me know if you have more questions.

I met the same problem as your.
The following is my command:
./app_tracking -sensor_type XP2 -cam_calib_path mysensor180601.yaml -pb_load data/room1.pb -path_follower walk -guide_ip 127.0.0.1 -guide_port 8887
no img_size is found in calib file. Using default value [752 x 480]

Do you have any approach to deal with this bug?
I'll appreciate you very much.

具体情况是这样的，如果运行官方编译好的程序app_tracking，没有问题，和手册中效果一样。但是自己编译出的app_tracking就没有地图，命令都是一样的，我重新存了张地图也不能读取，就是这样报错。
是不是两份代码不一样。

还有一个问题，为什么角度最大也就15，和注释里点单位不一样啊？

I solve this problem.
in line 650~700
Please modify them with the following code.Note my number of line is not same as yours possibly.
and I use cout,so add these codes
#include
using namespace std;
at the front of app_tracking.cpp

#ifdef SHOW_POSE_2D
// Use example 2D pose drawer
top_down_and_camera_canvas.create(PoseDrawer2D::imageSize,
PoseDrawer2D::imageSize + img_w, CV_8UC3);
top_down_view_canvas =
top_down_and_camera_canvas(cv::Rect(0, 0, PoseDrawer2D::imageSize,
PoseDrawer2D::imageSize));
cout<< "------------SHOW_POSE_2D"<<endl;
#else
// Use tracker drawer
// do not show trajectory history
if (FLAGS_show_both) {
top_down_and_camera_canvas.create(img_h, img_h + img_w * 2, CV_8UC3);
} else {
top_down_and_camera_canvas.create(img_h, img_h + img_w, CV_8UC3);
}
top_down_view_canvas =
top_down_and_camera_canvas(cv::Rect(0, 0, img_h, img_h));
// Trajectory view is an independent view
// Clear canvas before plotting
cout<<"---------------Use tracker drawer"<<endl;
#endif
// set to black
// 为什么要黑色
top_down_and_camera_canvas.setTo(cv::Vec3b(0, 0, 0));
cv::putText(top_down_and_camera_canvas, "Waiting for initialization",
cv::Point(15, 15), cv::FONT_HERSHEY_COMPLEX,
0.5, cv::Scalar(255, 255, 255), 1);
// Set camera_view_canvas as a sub-matrix of top_down_and_camera_canvas
// 把天眼视角和相机画布整个图的一部分给相机画布set函数画图
if (FLAGS_show_both) {
camera_view_canvas =
top_down_and_camera_canvas(cv::Rect(top_down_view_canvas.cols, 0,
img_w * 2, img_h));
} else {
camera_view_canvas =
top_down_and_camera_canvas(cv::Rect(top_down_view_canvas.cols, 0,
img_w, img_h));
}
XP_TRACKER::set_top_view_canvas(&top_down_view_canvas, false);
XP_TRACKER::set_camera_view_canvas(&camera_view_canvas);
//
cv::namedWindow("Top View & Left Camera");
cv::moveWindow("Top View & Left Camera", 0, 0);
} // FLAGS_show_simple
cv::imshow("Top View & Left Camera", top_down_and_camera_canvas);
